Ask Figlet about what love really is.

I’ve spent over 17 years sitting across from couples in crisis, couples in love, couples who thought love had died and couples who discovered it was never really alive to begin with. And what I can tell you, after thousands of sessions and more tears than I can count (theirs and mine), is that almost everything our culture teaches us about love is wrong. Not slightly wrong. Fundamentally, structurally, dangerously wrong.

So let me give you a different answer. One rooted not in greeting cards or romantic comedies, but in neuroscience, attachment theory, and the lived reality of what happens when two nervous systems try to make a life together.

What Is Love, Really? The Nervous System Answer

Here is the clinical truth: love is an attachment bond. It is a biological imperative rooted in human survival. It is not primarily a feeling, though feelings are part of it. It is not primarily a choice, though choices matter enormously. Love is what happens when your nervous system identifies another person as home.

That might sound cold. It is actually the warmest thing I know.

Because when you understand that love is biological, not just emotional, everything changes. The panic you feel when your partner pulls away? That is not you being “needy” or “codependent.” That is the predictable response of a mammalian nervous system that has detected a threat to its primary bond. Your body, at the deepest level of wiring, equates the loss of your primary attachment figure with a literal risk of death. Not metaphorically. Literally. We are not a species built for isolation. We are built for connection, and when that connection is threatened, our entire system mobilizes.

This is why breakups feel like dying. This is why silent treatments destroy people. This is why the question “what is love” matters so much, because if you define it wrong, you will spend your life chasing the wrong thing.

The Neuroscience of Love: What Your Brain Does When You Bond

If love is biological, then it has a biology. And that biology is far more intricate, more ancient, and more powerful than most people realize. Love is not one system in the brain. It is a cascade of overlapping systems, each evolved for a different purpose, each activated at different stages of a relationship.

Your Brain on Early Attraction

When you first fall for someone, your brain lights up like a city grid coming online after a blackout. The ventral tegmental area (VTA), a small region deep in the midbrain, floods your system with dopamine. This is the same region activated by cocaine, by gambling, by anything that creates the experience of “I need more of this.” Dopamine is not the chemical of pleasure exactly. It is the chemical of wanting. Of craving. Of “I cannot stop thinking about this person.”

Simultaneously, your norepinephrine levels spike. This is the chemical behind the racing heart, the sweaty palms, the inability to eat or sleep when you are newly infatuated. Your body is in a state of heightened arousal, and it is not an accident. It is your nervous system saying: pay attention. This matters.

And here is the part nobody tells you: your serotonin levels actually drop. Serotonin is the neurotransmitter associated with calm, with contentment, with the ability to put things in perspective. In the early stages of attraction, your serotonin profile looks remarkably similar to someone with obsessive-compulsive disorder. That is not a metaphor. Brain imaging studies have confirmed this. The reason you cannot stop thinking about someone new is that your brain has literally lost its ability to regulate obsessive thought.

This is what our culture calls “falling in love.” It is neurochemical weather. It is powerful, it is real, and it is temporary. Every single time.

The Bonding Chemicals: Oxytocin and Vasopressin

If dopamine is the chemical of craving, oxytocin and vasopressin are the chemicals of staying. These are the neurochemicals that build the actual bond, the durable, structural connection between two nervous systems that allows love to survive long after the dopamine storm has passed.

Oxytocin is released during skin-to-skin contact, during eye gazing, during orgasm, during breastfeeding, during moments of genuine emotional vulnerability. It is sometimes called the “love hormone,” but that label undersells it. Oxytocin does not just make you feel warm. It literally rewires your brain’s threat detection system. It tells your amygdala (the brain’s alarm center) to stand down. It says: this person is safe. You can lower your defenses here.

Vasopressin operates differently. It is more associated with long-term pair bonding, with protective behavior, with the drive to stay and guard the relationship. Studies on prairie voles (one of the few monogamous mammals) have shown that vasopressin receptor density in the brain is what separates monogamous species from promiscuous ones. Block the vasopressin receptors, and pair bonding collapses. The chemistry of commitment is not a metaphor. It is a receptor.

Here is what matters clinically: these bonding chemicals are not produced by thinking about your partner. They are produced by being with your partner. By touching. By looking into each other’s eyes. By being physically and emotionally present. This is why long-distance relationships are so hard. This is why couples who stop touching each other start feeling like roommates. The bond is not sustained by memory or intention. It is sustained by repeated, embodied, neurochemical experience.

The Amygdala and the Prefrontal Cortex: Why Fights Hijack Your Brain

Your amygdala is the brain’s smoke detector. It fires before your conscious mind even registers what is happening. When your partner says something that hits an old wound, your amygdala fires instantly, triggering a fight, flight, or freeze response before the rational brain even knows something happened.

When this happens, your prefrontal cortex, the part of your brain responsible for logic, perspective, empathy, and impulse control, goes offline. This is not a failure of character. It is neurobiology. You literally do not have access to your best thinking when your attachment system is in alarm. No access to logic. No access to the communication skills you learned in therapy last week. No access to perspective.

This is why couples in conflict say things they do not mean. Why they cannot hear each other. Why the same fight happens over and over with different content but identical emotional choreography. The amygdala does not care about content. It cares about threat. And in an attachment bond, emotional distance IS threat.

Understanding this neuroscience is not academic. It is the difference between seeing your partner as malicious and seeing them as hijacked. Between asking “why are you doing this to me?” and asking “what just got activated in you?” That shift in frame changes everything.

Love vs. Limerence: The Distinction That Could Save Your Relationship

If I could teach every person one distinction before they made a major relationship decision, it would be the difference between love and limerence.

Limerence is a term coined by psychologist Dorothy Tennov in 1979 to describe the intense, involuntary, obsessive state of romantic infatuation. It is characterized by intrusive thinking about the object of your desire, a desperate need for reciprocation, fear of rejection, idealization of the other person, and physical symptoms like heart pounding and stomach churning.

Limerence feels like love. It feels like the most real thing you have ever experienced. And that is precisely what makes it dangerous.

Limerence Is a Neurochemical Event, Not a Relationship

Limerence is what happens when your dopamine and norepinephrine systems are in overdrive and your serotonin is suppressed. It is a state of neurochemical intoxication. And like all intoxication, it distorts perception. The person you are limerent for is not the person standing in front of you. They are a projection, a screen onto which your nervous system has projected every unmet need, every childhood longing, every fantasy of finally being seen and chosen.

This is why limerence is so often confused with “knowing.” People in a limerent state will say things like: “I have never felt this way before.” “I just know this is different.” “This must be what real love feels like.” They are sincere. They are also neurochemically impaired.

How to Tell the Difference

Love and limerence feel different in the body, but only if you know what to look for.

Limerence feels like urgency. Love feels like arrival. Limerence is anxious, scanning, hypervigilant. Love is settled, grounded, present. Limerence needs constant reassurance. Love has internalized safety. Limerence cannot tolerate ambiguity. Love can hold uncertainty without collapsing. Limerence is about what this person does for my nervous system. Love is about who this person actually is.

The simplest diagnostic I offer clients: limerence makes you feel alive. Love makes you feel safe. If you can only feel alive and never safe, you are in limerence. If you can only feel safe and never alive, you may be in a bond that needs more vitality. But if you must choose one, choose safe. You can build alive on top of safe. You cannot build safe on top of alive.

Why People Leave Love for Limerence

This is the tragedy I see in my office more often than I care to admit. A person in a stable, loving relationship meets someone new. The dopamine hits. The obsessive thinking starts. Suddenly, their partner of ten years seems boring, predictable, insufficient. The new person seems to understand them in ways their partner never did.

What is actually happening is a neurochemical comparison between a mature bond (characterized by oxytocin, vasopressin, and calm) and a new limerent state (characterized by dopamine, norepinephrine, and chaos). Of course the limerent state feels more “real.” It is louder. It is more consuming. It hijacks every waking thought.

But it is not more real. It is more stimulating. And stimulation is not love. Stimulation is the match. Love is the fire that burns long after the match is spent.

What Culture Tells You Love Is (And Why It’s Wrong)

Our culture has sold us a story about love that goes something like this: You meet someone. There are sparks. You feel alive, seen, electric. If you’re compatible enough and communicate well enough, those sparks stay. If the sparks die, the love is dead. Move on. Find new sparks.

This is a catastrophically bad model of love.

It treats love as a consumer product. Something you shop for, evaluate, and replace when it stops performing. It confuses the neurochemical cocktail of early attraction (dopamine, norepinephrine, serotonin suppression) with the thing itself. It is like confusing the match with the fire, or the ignition with the engine.

In calm weather, everyone looks securely attached. In the early days, when your representative is doing all the talking and you have not yet been triggered by this person’s particular way of loading the dishwasher or forgetting to text back, love feels effortless. That effortlessness is not love. That is the absence of any real test of love.

Real love starts when the calm weather breaks.

The Seven Cultural Myths About Love That Destroy Relationships

After 17 years of clinical work, I have identified seven myths about love that cause the most damage. Each one sounds reasonable. Each one is wrong.

Myth 1: “You’ll just know.” The idea that real love is self-evident, that if you have to question it, it is not real. This myth causes people to abandon solid relationships the moment doubt enters (which it always does) and to cling to limerent highs because the certainty of obsession feels like “knowing.”

Myth 2: “Love should not be this hard.” This is the myth of effortless love, and it kills more good relationships than infidelity does. Love is not hard because something is wrong. Love is hard because you are trying to get two nervous systems, each shaped by different families, different wounds, different survival strategies, to co-regulate. That is inherently difficult. Difficulty is not a sign of failure. It is a sign of depth.

Myth 3: “You need to love yourself before you can love someone else.” This sounds wise. It is actually a barrier to connection dressed up as self-help. You do not learn to love yourself in isolation and then export that skill to a relationship. You learn to love yourself because someone else loved you first. Because someone showed you that you were lovable. The capacity for self-love is a relational achievement, not an individual one.

Myth 4: “Communication is the key to a good relationship.” Communication is important, but it is not the key. The key is safety. You can teach a couple every communication technique in existence, but if their nervous systems do not feel safe, they will not use any of them in the moments that matter. Safety first. Skills second.

Myth 5: “If they really loved you, they would change.” This myth confuses love with compliance. Your partner’s resistance to change is not evidence that they do not love you. It is evidence that change is terrifying, that their defenses are doing exactly what they were built to do (protect a wounded child), and that dismantling those defenses requires safety, not pressure.

Myth 6: “Your partner should be your best friend.” Your partner should be your primary attachment figure. That is different from a best friend. A best friend is someone you enjoy spending time with. An attachment figure is someone whose emotional availability is wired to your sense of survival. The expectations are different. The stakes are different. Treating your romantic partner like a friendship with benefits misses the entire biological architecture of what you are building together.

Myth 7: “The right relationship won’t trigger you.” This is perhaps the most damaging myth of all. The right relationship WILL trigger you. It will trigger you precisely because it matters enough to activate your deepest attachment wounds. A relationship that never triggers you is a relationship where you have never let the walls down far enough for real bonding to occur.

Fiat Intimacy: The Counterfeit Version of Love

I have a term for what most people mistake for love in the early stages of a relationship: fiat intimacy. Like fiat currency, it has no intrinsic value. It is intimacy by declaration rather than by earned experience.

Fiat intimacy is what happens when two people share their stories, their traumas, their “deep truths” on date three and feel like they have known each other forever. It feels real. It feels profound. But it has not been tested by anything. No conflict has threatened it. No trigger has exposed it. No real vulnerability (the kind that risks rejection, not the curated vulnerability of a first-date confession) has been required.

The problem with fiat intimacy is that it creates an illusion of depth without any of the structural integrity of real bonding. And when the first real storm hits, when the first fight reveals that this person is not your fantasy but an actual human with their own wounds and defenses, the fiat bond collapses. People mistake this collapse for falling out of love. They were never in love. They were in a shared fantasy.

Real intimacy, like a cryptocurrency built on proof of work, cannot be faked. It can only be earned through the caloric cost of genuine vulnerability over time. Through conflict survived. Through repair completed. Through the slow, unglamorous process of two nervous systems learning that the other is safe.

This is why the question “what is love” is so poorly served by romantic culture. Romantic culture celebrates fiat intimacy. It puts the high of early connection on a pedestal and treats everything after as decline. The truth is the opposite. Everything after is where love actually begins.

The Mango Problem: Why You Cannot Think Your Way Into Love

Here is something I tell my clients that tends to land hard: you cannot logic your way back into connection. You cannot read a book about mangos, analyze a mango’s texture and origin for an hour, describe its sweetness in perfect detail, and call that the same thing as tasting the mango.

Sound love is not intellectual. It is experiential. It is felt in the body. It is a physiological reality that two people create together, in real time, in the present moment.

This matters because most people who are struggling in their relationships are trying to think their way out of the problem. They read articles (like this one, yes, the irony is not lost on me). They listen to podcasts. They buy workbooks. They compile a mental database of communication techniques and attachment styles and love languages.

And then, in the moment when their partner says something that hits an old wound, all of that intellectual knowledge vanishes. The nervous system takes over. The younger self inside the adult body runs the show.

Understanding what is love intellectually is a starting point. But it is only a starting point. The real work happens in the body, between two bodies, in the messy and terrifying space of actual vulnerability.

Love as Proof of Work: What It Actually Takes

There is a concept I use with my clients that I call “proof of work.” It comes from cryptography, but it applies perfectly to relationships.

In cryptography, proof of work means you cannot fake the output. You have to actually do the computational work to produce a valid result. There is no shortcut.

Love works the same way.

You cannot shortcut your way to secure attachment. You cannot hack trust. You cannot fake safety. You have to actually do the work, which means showing up, rupturing, repairing, rupturing again, repairing again, over and over, until your nervous systems learn that this bond can survive conflict. That this person will still be there on the other side.

Our culture pushes a narrative that says you need to heal yourself first. Become emotionally self-regulated. Get your act together. Then you will be ready for love.

I am going to push back on that hard.

Individual sovereignty and emotional self-regulation are not prerequisites to connection. They are emergent properties that arise exclusively through the grueling proof of work of being safely met while dysregulated.

Read that again.

You do not get regulated alone so you can show up regulated in love. You get regulated because someone met you in your dysregulation with compassion instead of contempt. That is how love rewires the nervous system. That is how love heals.

We do not become sovereign alone. We become sovereign in relationship. In repair.

What Proof of Work Looks Like in Practice

Let me make this concrete, because “proof of work” can sound abstract if you have never seen it in action.

Proof of work is the caloric cost of paying attention when you are tired, triggered, and wanting to check your phone. It is crossing the bridge into your partner’s reality when every cell in your body wants to defend your own. It is letting go of being right. That burns calories. That costs ego.

Your body is the original distributed ledger. It records every trauma, every betrayal, every moment of safety. Your nervous system operates as a strict proof-of-work protocol. It will only validate the transaction when the safety is real. You cannot talk your way past this system. You cannot promise your way past it. You have to demonstrate, repeatedly, through embodied action, that you are a safe person to need.

An “I love you” without behavior change is quantitative easing for the heart. An apology without true empathy is an artificial cherry on a cake that does not exist. Your partner’s nervous system knows the difference, even if their conscious mind wants to believe you.

The Time Machine: Why Your Fights Are Never About What They’re About

If you want to understand what is love at the deepest level, you have to understand this: every fight you have with your partner is a time-travel event.

When your partner criticizes you and your chest tightens and your jaw locks, that is not a 38-year-old responding to feedback. That is a 6-year-old who learned that criticism means “you are not enough.” When your partner withdraws and you feel the panic rising, that is not an adult experiencing a normal pause in conversation. That is a child who learned that silence means abandonment.

Partners in conflict are just two younger selves inside adult bodies. Their triggers are time machines, catapulting them back to replay childhood survival strategies. One learned to pursue, to chase, to demand, because in their family, if you did not fight for attention, you disappeared. The other learned to withdraw, to shut down, to go internal, because in their family, showing emotion was dangerous.

Neither strategy is wrong. Both made perfect sense at the time. Both are devastating in an adult relationship when they collide.

Love, real love, is the act of recognizing this. Of seeing past the adult armor to the child underneath. And then doing something radical: providing the missing experience.

The Missing Experience: How Love Actually Heals

The missing experience is the clinical heart of what makes love transformative. Here is how it works.

When your partner is triggered, when they are flooded with old pain and their younger self is running the show, you have a choice. You can meet them with your own trigger (which is what happens in most fights). Or you can hold steady, stay present, and offer them something they never got.

If their wound is “I am too much,” you tell them, with your words and your body and your nervous system: you are never too much.

If their wound is “I am a disappointment,” you tell them: you could never disappoint me.

When this happens, something remarkable occurs neurologically. The brain writes a new file. A new experience that contradicts the old one. And over time, with enough repetitions, that new file begins to overwrite the old trauma. The nervous system literally rewires. New neural pathways form. The body learns, at a cellular level, that this bond is safe.

This is not a metaphor. This is neuroscience. This is what love does when it is working.

Empathy Cubed: The Framework for Real Connection

To actually provide the missing experience, you need a specific kind of empathy. Not just empathy for your partner (which is what most therapy teaches). Not just empathy for yourself (which is what most self-help teaches). You need what I call Empathy Cubed: compassion for me, compassion for you, and compassion for the tragic system we co-create together.

That third piece is the game-changer.

Because most couples are stuck in a binary. Either I’m the problem or you’re the problem. Either my pain matters or yours does. Empathy Cubed breaks that binary. It says: your hurt makes sense. Your reaction makes sense. My hurt makes sense. My protector makes sense. And the pattern we fall into together, the cycle that consumes us both, that makes sense too.

When both partners can hold all three dimensions of empathy simultaneously, something shifts. The war ends. Not because the problems are solved, but because the frame has changed. You are no longer two opponents. You are two wounded people caught in a system that is bigger than either of you. And that system can be changed.

Love and the Nervous System: The Polyvagal Connection

To fully understand what is love, you need to understand the nervous system that makes it possible. And that means understanding polyvagal theory.

Stephen Porges’ polyvagal theory describes three states of the autonomic nervous system, each of which profoundly shapes how you experience love.

Ventral Vagal: The State of Connection

When your ventral vagal system is active, you are in what Porges calls the “social engagement system.” Your face is expressive. Your voice is warm and melodic. Your heart rate is regulated. You can make eye contact without feeling threatened. You can hear your partner’s words without filtering them through a threat lens.

This is the state in which love happens. Not just romantic love, but all forms of genuine human connection. Your body is sending and receiving signals of safety. Your partner’s nervous system picks up those signals (often unconsciously) and begins to co-regulate. Two ventral vagal systems in contact create what I call “the field.” It is palpable. Couples in this state often describe feeling “at home” with each other, and they are describing a literal neurophysiological event.

Sympathetic Activation: Fight or Flight

When your nervous system detects a threat (real or perceived), you shift into sympathetic activation. Heart rate increases. Muscles tense. Vision narrows. Adrenaline floods the system. In a relationship, this state manifests as pursuit, as criticism, as desperate bids for connection that come out as attacks.

The pursuer in a relationship cycle is almost always in sympathetic activation. They are not “nagging.” They are in fight mode because their attachment system has detected emotional distance and interpreted it as danger. Their body is saying: do something. Fix this. Get them back. Now.

Dorsal Vagal: Freeze and Shutdown

When sympathetic activation does not resolve the threat, or when the threat feels overwhelming, the nervous system drops into dorsal vagal shutdown. This is the freeze response. The body goes still. Emotion goes flat. The person “checks out.” They may be physically present but emotionally gone.

The withdrawer in a relationship cycle is often in dorsal vagal shutdown. They are not “stonewalling.” They are not “being cold.” Their nervous system has decided that the threat is too great to fight, so it has chosen the only remaining option: play dead. Go numb. Wait for it to pass.

When one partner is in sympathetic activation (pursuing, critical, panicking) and the other is in dorsal vagal shutdown (withdrawing, shutting down, going blank), you have the most common pattern in couples therapy. It is not a communication problem. It is a nervous system mismatch. And solving it requires not better words, but co-regulation: one nervous system helping the other find its way back to safety.

Co-Regulation: The Nervous System’s Definition of Love

If I had to define love in purely neurobiological terms, I would define it as co-regulation. The capacity of one nervous system to help another nervous system return to a state of safety.

This is what the baby needs from the parent. It is what the adult needs from the partner. It is, in the most literal sense, what love IS at the level of the body. Not a feeling. Not a choice. A regulatory function.

When you hold a crying baby and they calm in your arms, that is co-regulation. When your partner is spiraling and you hold them steady and they begin to breathe again, that is co-regulation. When your partner says “I’m here, I’m not going anywhere” and your chest unclenches, that is co-regulation.

Every act of love you have ever witnessed, stripped to its biological core, is one nervous system communicating safety to another. That is the whole game.

Love by Attachment Style: How Your Wiring Shapes Your Experience

John Bowlby, the father of attachment theory, described love as an emotional bond that humans need from cradle to grave. He was not being poetic. He was describing a biological system that shapes every intimate relationship you will ever have.

Your attachment style, forged in the first years of life, is the operating system through which you experience love. And understanding your style is not a luxury. It is a necessity. Because the way your nervous system was wired in childhood is the way it will respond in adult love, until and unless new experiences rewire it.

Secure Attachment: Love as a Safe Harbor

A person with secure attachment experiences love as a safe harbor. They can express their needs without shame. They can tolerate their partner’s separateness without panic. They can hold conflict without interpreting it as the end of the relationship. When triggered, they can self-regulate AND reach for their partner. They have both capacities.

Ask Figlet about what love really is.

Secure attachment does not mean you never feel anxious or avoidant. It means your baseline is flexible. You can move toward your partner when you need connection and move away when you need space, and neither movement feels like a crisis.

Roughly 50-60% of the population is securely attached. The rest of us are working on it. And the good news is that attachment styles are not fixed. They are patterned responses, and patterns can be changed through corrective emotional experiences. That is what good love does. That is what good therapy does.

Anxious Attachment: Love as a Fire Alarm

A person with anxious attachment experiences love as a fire alarm that is always on the verge of going off. They are hypervigilant to signs of disconnection. They scan their partner’s face, tone, and behavior for evidence that the bond is under threat. When they detect distance (real or imagined), their system goes into overdrive. They pursue. They seek reassurance. They escalate.

This is not a character flaw. It is a nervous system adaptation. Somewhere in childhood, this person learned that caregivers were inconsistently available. Sometimes present, sometimes not. Sometimes warm, sometimes cold. The child’s nervous system solved this problem the only way it could: by turning up the volume on attachment needs. By becoming exquisitely sensitive to any signal that the caregiver might disappear.

In adult love, this wiring creates a painful paradox. The anxiously attached person’s pursuit of closeness often triggers the very withdrawal they fear. Their intensity overwhelms their partner, who pulls away, which confirms the anxious person’s worst fear, which intensifies their pursuit. The cycle feeds itself.

Avoidant Attachment: Love as a Trap

A person with avoidant attachment experiences love as a potential trap. Closeness feels dangerous. Dependency feels like weakness. Emotional demands feel like threats to autonomy. When a partner moves toward them with emotional intensity, their system says: too close. Pull back. Protect yourself.

Again, this is not a choice. It is a nervous system adaptation. Somewhere in childhood, this person learned that their emotional needs would not be met, or worse, that expressing those needs would result in rejection or punishment. The child’s nervous system solved this by suppressing attachment needs entirely. By becoming self-sufficient. By building an identity around not needing anyone.

In adult love, this wiring creates a different kind of pain. The avoidantly attached person often genuinely wants closeness but cannot tolerate it when it arrives. They feel suffocated by precisely the intimacy they crave. They push away the people they love most. And because our culture rewards independence and pathologizes neediness, they often receive cultural validation for a pattern that is actually keeping them isolated.

Disorganized Attachment: Love as Both Rescue and Danger

A person with disorganized attachment experiences love as simultaneously the source of safety and the source of threat. This style typically develops when the primary caregiver was both the source of comfort and the source of fear (as in cases of abuse, severe neglect, or caregiver mental illness).

The child’s nervous system faced an impossible dilemma: the person I need to run to for safety is the same person I need to run from. This creates a fractured approach to intimacy in adulthood. The person may oscillate between intense pursuit and sudden withdrawal. They may crave closeness and then sabotage it the moment it arrives. They may feel simultaneously terrified of abandonment and terrified of engulfment.

Disorganized attachment is the most painful style to live with and the most challenging to treat. But it is not a life sentence. With consistent, predictable, safe relational experiences (in therapy and in love), the nervous system can learn a new pattern. It just takes more time and more repetitions of safety.

What Is Love in Practice? A Story From My Own Marriage

I want to tell you a story, because I think it illustrates what love actually looks like better than any framework can.

My wife Teale and I were on a trip to Dublin. I made a careless joke that landed on her like a knife. In a younger version of our relationship, this would have triggered our negative cycle. I would have felt the shame of having hurt her and withdrawn into my protector. She would have felt dismissed and pursued harder. The cycle would have consumed the evening, maybe the trip.

But that is not what happened.

What happened is that we did the proof of work of repair. We held complete empathy for both of us. Her hurt made sense. Her reaction made sense. My hurt made sense. My protector made sense. From that regulated place, we gave each other the missing experience. I let Teale know that she is never too much. She let me know that I am not a disappointment.

We held each other in the places our childhoods left tender. That is repair. That is the Sovereign Us.

I am not telling you this story because my marriage is perfect. I am telling you because it is not. Because love, real love, is not the absence of rupture. It is the presence of repair. It is not a destination. It is a rhythm.

The Sovereign Us: Love as a Place You Return To

The Sovereign Us is my term for what secure love actually looks like in practice. And the most important thing I can tell you about it is this: it is not a permanent state.

You lose it. You come back. You lose it. You come back. That is the rhythm. That is the heartbeat of a living relationship.

The Sovereign Us is not two people who never fight. It is two people who have built enough trust through repair that their nervous systems know, at the deepest level, that conflict will not destroy the bond. It is the physiological rhythm of “Come here to me. No, you come here to me.”

This is what is love at its most mature. Not the absence of pain, but the confidence that pain can be held together. Not the absence of distance, but the trust that distance is always temporary. Not perfection, but the predictable return to safety.

The Drawbridge: Boundaries With Connection

Culture gives us two options for protecting ourselves in love: walls or no walls. Build walls and you are “guarded” or “avoidant.” Have no walls and you are “enmeshed” or “codependent.”

Both options are wrong.

I see this constantly in my practice. Clients who have been told by previous therapists or by the internet that they need “better boundaries,” which they interpret as building higher walls. Or clients who have been told they are “too guarded” and interpret that as needing to collapse all boundaries entirely. Both paths lead to the same place: isolation disguised as either strength or openness.

The right image is a drawbridge. Boundaries with connection. Autonomy without exile. A drawbridge gives you the flexible capacity to protect yourself when necessary, but you actively choose to lower the bridge because you are built for connection. It is not rigidity. It is not collapse. It is sovereignty.

The drawbridge represents the paradox at the heart of love: you need to be your own person AND you need your person. Both things are true. Both things are biological. And holding both is the work of a lifetime.

The Five Clinical Forms of Love

Love is not one thing. It is a family of related experiences, each with different neurobiological profiles, different relational functions, and different developmental timelines. When clients ask me “what is love,” I often ask back: which form?

1. Attachment Love: The Bond of Safety

This is the form of love described by Bowlby and elaborated by Sue Johnson: the deep, enduring bond that forms between primary attachment figures. It is characterized by proximity seeking (wanting to be near the person), safe haven (turning to them in distress), secure base (using the bond as a foundation for exploration), and separation distress (pain when the bond is threatened).

Attachment love is the bedrock. Without it, the other forms of love may exist, but they will be unstable, built on shifting sand.

2. Caregiving Love: The Drive to Protect

Caregiving love is the impulse to nurture, to protect, to attend to the other’s pain. It is the form of love that makes a parent rush to a crying child. In adult relationships, it is the form that makes you want to hold your partner when they are hurting, to shield them from harm, to give them what they need before they ask.

Caregiving love is mediated heavily by oxytocin and is closely tied to the social engagement system. When it is balanced (both partners giving and receiving care), it deepens the bond. When it is unbalanced (one partner always caregiving, the other always receiving), it becomes exhausting and resentful.

3. Sexual Love: The Chemistry of Desire

Sexual love is the form driven primarily by testosterone, estrogen, and the dopaminergic reward system. It is the form that creates physical desire, erotic energy, and the drive to merge bodies. In long-term relationships, sexual love often diminishes not because the love has died but because the neurochemical profile of the relationship has shifted from dopamine-driven craving to oxytocin-driven bonding.

The clinical challenge is maintaining sexual love alongside attachment love. They operate on different neurochemical tracks, and they can sometimes work against each other. The safety and predictability that deepen attachment can reduce the novelty and uncertainty that fuel desire. Navigating this tension is one of the great ongoing projects of long-term partnership.

4. Companionate Love: The Comfort of Presence

Companionate love is the form characterized by deep affection, comfort, and shared life. It is the love of best friends, of long-married couples who have built a life together, of partners who find genuine pleasure in each other’s company. It does not have the intensity of early romantic love, and our culture tends to devalue it for that reason. But companionate love is the form that actually predicts relationship satisfaction over decades.

Research by John Gottman and Robert Levenson has shown that the couples who stay together and stay happy are not the ones with the most passion. They are the ones with the most friendship. The ones who turn toward each other’s bids for connection. The ones who know each other’s worlds.

5. Self-Compassionate Love: The Relationship With Yourself

This form is often overlooked in discussions of romantic love, but it is clinically essential. Self-compassionate love is the capacity to extend to yourself the same warmth, understanding, and acceptance that you would extend to someone you love deeply.

This is not self-esteem (which is evaluative and conditional). It is not self-indulgence (which avoids accountability). It is the ability to be with your own pain without abandoning yourself. To notice your own defenses without shaming yourself for having them. To forgive your own failures without minimizing them.

Self-compassionate love is what allows you to show up in a relationship without requiring your partner to be the sole source of your emotional regulation. It does not replace the need for attachment love. But it complements it. It means you can hold yourself when your partner cannot, without interpreting their inability as abandonment.

Love Across the Lifespan: How Love Changes and Deepens

One of the most common misunderstandings about love is that it should feel the same at year twenty as it did at month two. It should not. It cannot. And expecting it to is one of the fastest ways to destroy a perfectly good relationship.

Love in the First Two Years: The Limerent Phase

The first phase of romantic love is dominated by limerence, that dopamine-driven, obsessive, all-consuming experience I described earlier. This phase serves a biological purpose: it gets two people bonded quickly enough to reproduce and begin co-parenting before the rational brain has time to run a cost-benefit analysis.

During this phase, the brain’s critical faculties are literally suppressed. The areas responsible for negative judgment and social assessment are less active. You are, from a neuroscience perspective, seeing your partner through rose-colored glasses because your brain has decided that bonding is more important than accurate evaluation.

This phase typically lasts 6 to 24 months. It always ends. Always. And its ending is not a tragedy. It is a transition.

Love in Years Two Through Seven: The Power Struggle

When the limerent phase fades, the neurochemical profile of the relationship shifts. Dopamine decreases. The critical faculties come back online. Suddenly, you can see your partner clearly, and what you see is not always what you signed up for.

This is the phase where couples start fighting about dishes and finances and in-laws. But as I said earlier, those fights are never about what they are about. They are about attachment. They are about “are you there for me?” and “am I enough for you?” played out through the medium of who forgot to take out the trash.

This is also the phase where most divorces happen (the seven-year itch is not a myth, it is a neurobiological pattern). Couples who interpret the loss of limerence as the loss of love will exit here. Couples who understand that love is just beginning will stay and do the work.

Love in the Long Haul: The Mature Bond

For couples who survive the power struggle and do the proof of work of repair, something remarkable happens. The bond deepens into what researchers call “mature love” or what I call the Sovereign Us.

This form of love is quieter than limerence but far more powerful. The oxytocin and vasopressin systems are fully engaged. The couple has built a library of shared experience, of rupture and repair, of being seen at their worst and still being chosen. Their nervous systems have learned, through thousands of micro-interactions, that this bond is durable.

Mature love is not exciting in the way early love is exciting. But it is safe in a way that early love cannot be. And safety, in the currency of the nervous system, is the most valuable thing that exists.

Brain imaging studies of couples who report being deeply in love after 20+ years show something extraordinary: their brains still light up in the VTA (the dopamine center) when they see their partner’s face, but they also show activation in brain regions associated with calm, with pain relief, with long-term memory. They have the spark AND the safety. The match AND the fire. This is what is possible when two people do the work.

Relationship Distress Is a Feature, Not a Bug

One of the most radical things I can say about what is love is this: relationship distress is a feature, not a bug, of loving someone so much that their emotional distance feels terrifying.

Read that again, slowly.

Your pain is not evidence that something is wrong with your relationship. Your pain is evidence that your attachment system is working. It is doing exactly what it was designed to do: sounding the alarm when your primary bond is under threat.

The couple who sits in my office convinced they are “broken” because they fight about everything is not broken. They are two people whose nervous systems are screaming for connection and whose childhood survival strategies keep getting in the way. The pursuer is not “controlling.” They are terrified of abandonment. The withdrawer is not “cold.” They are terrified of being overwhelmed and found inadequate.

When I can help a couple see this, when they can stop seeing each other as the enemy and start seeing the cycle as the enemy, everything shifts. The cycle is the villain. Not your partner. Not you. The cycle. And the cycle can be interrupted. It can be replaced with a new pattern, one built on the proof of work of showing up differently, even when every cell in your body is telling you to run your old play.

This is what therapy does when it works. Not teach communication skills. Not assign blame. Not adjudicate who is right. It interrupts the cycle and creates the conditions for a new experience. One repair at a time.

What Happens When Love Is Absent

If love is a biological imperative, then its absence is not merely sad. It is physiologically destabilizing.

Research consistently shows that people in distressed relationships have higher cortisol levels, weaker immune function, slower wound healing, and elevated cardiovascular risk. Loneliness, which is the subjective experience of an unmet attachment need, is as significant a risk factor for early mortality as smoking 15 cigarettes a day. This is not poetry. This is epidemiology.

When I sit with a client who tells me they have not been touched with genuine warmth in months, who tells me their partner looks through them like glass, who tells me they cannot remember the last time they felt safe enough to cry in front of someone, I am not hearing a story about “relationship problems.” I am hearing a story about a mammal whose survival system is offline. Whose nervous system is in a chronic state of threat. Whose body is slowly being eroded by the absence of what it was built to need.

If any of this is landing close to home, you can talk it through right now with Figlet, Figs’ AI mini me, and get an answer about your own situation in seconds. Ask Figlet about what love really is..

This is why the question of what is love is not philosophical. It is medical. It is existential. Getting love right is not a luxury. It is a health outcome.

What Research Says About Lasting Love

The empirical research on lasting love converges on a set of findings that confirm everything I have seen clinically. These are not opinions. These are replicated findings.

Gottman’s Research: The Four Horsemen and the Magic Ratio

John Gottman’s four decades of research at the University of Washington produced one of the most robust findings in relationship science: he can predict divorce with over 90% accuracy based on how a couple handles conflict. The predictors are not what you might expect. They are not about how much a couple fights. They are about how they fight.

Gottman identified four patterns that predict relationship dissolution: criticism (attacking the partner’s character rather than behavior), contempt (expressing disgust or superiority), defensiveness (deflecting responsibility), and stonewalling (shutting down and disengaging). He called these the Four Horsemen of the Apocalypse.

The antidote to the Four Horsemen is not the absence of conflict. It is the presence of repair. Gottman’s research found that stable, happy couples have a ratio of approximately 5:1 positive to negative interactions. They are not avoiding negativity. They are overwhelming it with positivity. With bids for connection. With turning toward instead of turning away.

Sue Johnson’s Research: EFT and the Science of Bonding

Sue Johnson, the creator of Emotionally Focused Therapy (EFT), has built one of the most researched and validated approaches to couples therapy in existence. EFT is grounded in attachment theory and works by helping couples identify their negative cycle, access the vulnerable emotions underneath their defenses, and create new bonding experiences that restructure the attachment bond.

The research on EFT shows that 70-75% of couples move from distress to recovery, and approximately 90% show significant improvement. These are extraordinary numbers for any therapeutic intervention. And the results hold over time. Follow-up studies show that the gains from EFT are maintained and often continue to improve after therapy ends. The bond, once restructured, continues to deepen.

The Harvard Study of Adult Development: 85 Years of Data

The Harvard Study of Adult Development, which has tracked participants since 1938, is the longest-running study of human happiness ever conducted. Its central finding, after 85 years of data, is unambiguous: the quality of your close relationships is the single strongest predictor of health, happiness, and longevity. Not money. Not career success. Not genetics. Relationships.

Robert Waldinger, the study’s current director, summarizes it simply: “Good relationships keep us happier and healthier. Period.” The participants who were most satisfied in their relationships at age 50 were the healthiest at age 80. The people who maintained warm connections lived longer and reported more life satisfaction than those who were socially isolated, regardless of income, IQ, or social class.

This is the empirical foundation beneath everything I have written in this article. Love is not a luxury. It is the single most important factor in human wellbeing. The science is clear.

Why “What Is Love” Is the Wrong Question (And the Right One)

Here is the paradox of this entire article: asking “what is love” is both the most important question you can ask and the most misleading.

It is misleading because it implies love is a thing. A noun. Something you have or do not have, find or lose. And as I have spent thousands of words arguing, love is not a thing. It is a process. A cycle. A biological rhythm of rupture and repair that two nervous systems create together over time.

But it is also the most important question, because if you get the answer wrong, you will spend your life chasing the wrong thing. You will chase sparks instead of safety. You will chase excitement instead of regulation. You will leave good relationships because they stopped feeling “exciting” and stay in destructive ones because the chaos feels like “passion.”

So here is my final answer, after 17 years and thousands of couples: what is love is the willingness to stay in the ring. To see your partner’s pain and not run from it. To see your own pain and not weaponize it. To rupture and repair, rupture and repair, until your bodies learn what your minds already know, that you are home.

Love Is Not Independence. Love Is Not Dependence. Love Is Interdependence.

Our culture worships independence. The self-made person. The emotionally bulletproof individual who needs no one. Therapy culture, ironically, often reinforces this. “You need to love yourself first.” “You cannot pour from an empty cup.” “Do the inner work.”

I am not against inner work. I do inner work. But I reject the premise that inner work is something you complete before you show up in love. The inner work IS the love. The love IS the inner work. They are the same thing.

Needing emotional connection is a biological imperative, not a weakness. Your need for your partner is not a flaw to be fixed. It is the engine of your healing. The way you hurt is the best part of who you are, because it shows you where love still needs to go.

Interdependence means: I am whole on my own AND I am more whole with you. I can regulate myself AND I regulate better with your help. I have my own identity AND my identity expands in the safety of our bond.

This is what love is. Not a feeling. Not a choice. Not a contract. A biological, neurological, physiological process by which two nervous systems learn to be home for each other, one repair at a time.

Surrendering to Who You Are

There is one more piece to this, and it might be the most important.

True love requires you to surrender to who you are. Not who you wish you were. Not the version of yourself that has it all together. Not your representative, not your protector, not the mask you built to survive childhood. Your actual self. The one who is scared. The one who is needy. The one who is “too much” or “not enough” or whatever label your family of origin slapped on the parts of you that did not fit.

Most people spend their entire lives running from this self. They build careers, curate social media presences, develop elaborate coping strategies, all in service of never having to show this self to another person. And then they wonder why their relationships feel hollow.

Love cannot reach you through armor. It can only reach you through the gaps. The moments where you let the mask slip, where you say the thing you are terrified to say, where you show the wound instead of the weapon. Those moments are where love enters.

And here is the beautiful paradox: the parts of you that you are most ashamed of, the parts you have spent your whole life hiding, those are often the parts your partner most needs to see. Because those parts are where the missing experience lives. Your partner cannot provide what you never got if they do not know what is missing.

The way you hurt is the best part of who you are. It is the doorway to connection. It is the place where love does its deepest, most transformative work.

Frequently Asked Questions About Love

What is love, scientifically?

Love, scientifically, is an attachment bond. It is a biological system rooted in survival that evolved to keep mammals close to their caregivers (and later, their reproductive partners). At the neurochemical level, love involves dopamine (craving and reward), oxytocin (bonding and trust), vasopressin (long-term pair bonding), norepinephrine (arousal and attention), and serotonin modulation (obsessive focus in early stages). At the nervous system level, love is the process of co-regulation: one nervous system helping another return to safety.

Is love a feeling or a choice?

Love is neither a feeling nor a choice in isolation. It is a biological process that involves both. The feeling component (attachment, longing, comfort in someone’s presence) is generated by your nervous system and is not something you can simply decide to feel or not feel. The choice component (showing up, repairing after conflict, prioritizing the bond) is what sustains the biological bond over time. Feelings without action are incomplete. Action without feeling is performance. Love requires both.

Can you fall out of love?

You can fall out of limerence. Limerence (the obsessive, dopamine-driven high of early attraction) always fades, typically within 6-24 months. If you equate that high with love, then yes, you will “fall out of love” with every partner you ever have. But if you understand love as an attachment bond, then “falling out of love” is more accurately described as a bond that has been damaged by chronic disconnection, unrepaired ruptures, and accumulated resentment. Bonds can be repaired. In most cases, “falling out of love” is not a terminal diagnosis. It is a signal that the bond needs attention.

How do I know if it is love or limerence?

Limerence feels like urgency. Love feels like arrival. Limerence is obsessive, anxious, and cannot tolerate ambiguity. Love is grounded, present, and can hold uncertainty. Limerence idealizes the other person. Love sees them clearly and chooses them anyway. Limerence makes you feel alive. Love makes you feel safe. If you can only feel intensity and never peace, you are likely in limerence. If you feel a settled warmth and a willingness to stay through difficulty, you are likely in love.

Why does love hurt so much?

Love hurts because your nervous system equates your primary attachment bond with survival. When that bond is threatened (through conflict, distance, betrayal, or loss), your body responds as though your life is at risk. This is not an overreaction. It is the predictable response of a mammalian nervous system that evolved in an environment where losing your primary attachment figure meant death. The pain of love is the price of caring about something your biology considers essential to your existence.

What is the difference between love and attachment?

Attachment is the biological system. Love is the lived experience of that system in action. Attachment describes the wiring: the neural pathways, the neurochemical cascades, the behavioral patterns that bind two people together. Love is what it feels like from the inside. Think of it this way: attachment is the hardware. Love is the experience of running the software. You can describe attachment without ever using the word love, and you can feel love without knowing anything about attachment theory. But they are describing the same phenomenon from different vantage points.

Can you love someone and still feel insecure?

Absolutely. In fact, insecurity in the context of love is one of the most common human experiences. Your attachment style (shaped by your childhood experiences) determines how much insecurity you bring into a relationship, regardless of how loving your partner is. A person with anxious attachment can be deeply loved and still feel chronically insecure because their nervous system is wired to expect inconsistency. The path to security is not finding the “right” partner who eliminates all insecurity. It is finding a partner willing to do the proof of work of consistent, reliable, embodied safety over time, so that your nervous system can gradually update its predictions.

Is love enough to make a relationship work?

Love is necessary but not sufficient. A couple can love each other deeply and still destroy their relationship through chronic negative cycles, untreated trauma, addiction, or an unwillingness to do the work of repair. Love creates the motivation. Skill, courage, and consistent effort create the outcome. The couples I see who make it are not the ones who love each other the most. They are the ones who are most willing to show up, be vulnerable, and repair when they inevitably fail.

How do I fix my relationship?

You do not fix a relationship the way you fix a car. A relationship is not a machine with broken parts. It is a living system with a negative cycle that needs to be interrupted and replaced with a new pattern. The first step is always the same: see the cycle. See how your defense triggers their defense, which triggers your defense, which triggers theirs. Externalize the cycle as the enemy, not each other. Then, begin the slow work of providing the missing experience, meeting each other’s wounds with compassion instead of reactivity. If you cannot do this on your own (and most couples cannot, because the triggers are too fast and too deep), find a therapist trained in Emotionally Focused Therapy (EFT). It is the most researched and effective approach to repairing attachment bonds.

What does healthy love look like?

Healthy love looks like two people who fight, repair, and return to safety. Who can express their needs without shame and hear their partner’s needs without defensiveness. Who can tolerate separateness without panic and tolerate closeness without suffocation. Who turn toward each other more often than they turn away. Who know each other’s wounds and handle them with care. Healthy love is not the absence of conflict. It is the presence of repair. It is not two perfect people. It is two imperfect people who have decided that the bond is worth the work.

What to Do With This

If you have read this far, you are probably not someone who is casually browsing. You are probably someone who is hurting, or someone who loves someone who is hurting, or someone who senses that what they have been told about love does not match their experience.

Trust that instinct. Your nervous system knows things your conscious mind does not. The fact that you are asking what is love means something in your system is searching for a more honest answer.

Here is what I want you to take away:

Love is not the spark. Love is what remains after the spark has done its job. The spark gets you into the ring. Love is the decision to stay.

Your fights are not evidence that love has failed. They are evidence that love matters enough to trigger your deepest wounds. The question is not whether you fight. The question is whether you repair.

You do not need to be healed to be loved. You need to be loved to be healed. Find someone willing to do the proof of work with you. Be someone willing to do the proof of work with them.

And if you are not sure where you stand, if you sense something is off but cannot name it, start by understanding your own pattern. Because the pattern is the key. Once you see it, you cannot unsee it. And once you cannot unsee it, you can change it.
