Codependency Is Not What You Think It Is

By Figs O’Sullivan, LMFT | April 15, 2026 | 12 min read

I want to say something that might catch you off guard: I will not hear you call yourself codependent. I won’t hear it. I will not sit across from you in my office and let you label the part of you that is fighting for love a bad part. I refuse.

I know that sounds strange coming from a therapist. You probably came to this article because you Googled “codependency” looking for confirmation that something is wrong with you. That the way you love too hard, give too much, or lose yourself in your partner’s pain is evidence of a disease. The internet is full of checklists and Instagram infographics telling you exactly that. And I think most of them are getting it dangerously wrong.

After 16 years of working with couples, and after growing up as the son of an alcoholic, I have a very different relationship with the word codependency than most clinicians. I’ve seen what it does when someone walks into therapy already believing they are broken for loving someone difficult. That belief doesn’t heal anything. It just adds shame to an already painful situation.

So let’s talk about what codependency actually is, where the term came from, why I think it misses the point, and what you can do instead of pathologizing yourself.

What Is Codependency, Really?

The term codependency originated in the late 1970s and early 1980s within the addiction treatment community. Clinicians working with families of alcoholics noticed a pattern: the spouse or partner of the addict seemed to organize their entire life around managing the addict’s behavior. They would cover for them, clean up their messes, suppress their own needs, and become hypervigilant to every shift in mood.

Researchers labeled this codependency, framing it as a kind of relational addiction. The idea was that the partner was “addicted to being needed” in the same way the alcoholic was addicted to the substance. The concept became a parallel diagnosis, a mirror image of the addict’s disease. Books were written. Treatment programs were built. The concept exploded into popular culture.

Here is the problem: the original researchers who coined this term didn’t understand attachment theory. They were looking at human bonding behavior through the lens of addiction, and that lens distorted everything. What they saw as pathology was, in many cases, a completely predictable and even adaptive response to an impossible relational situation.

Think about it. A partner of an addict accurately determines that their spouse is incapable of showing up consistently. The ground beneath the relationship is unstable. So what does the partner do? They make sacrifices to maintain the connection. They suppress their own needs. They become hyperattuned to the other person’s emotional state. And then a clinician walks in and tells them they have a disease, as if their survival strategy is the problem.

That has never sat right with me.

Why “Codependency” Is the Wrong Word

Here is my core clinical position, and I say this with full conviction: codependency is a myth. Not the behaviors. The behaviors are real. The suffering is real. But the framework that calls those behaviors a disease is built on a misunderstanding of how human attachment works.

When you lose yourself in your partner’s pain, that is not a disorder. That is a normal attachment adaptation. It is how you learned to survive not being loved the way you needed. Your nervous system figured out early (often in childhood) that the way to maintain proximity to your caregiver was to attune to their emotional state, suppress your own needs, and make yourself indispensable. That strategy kept you connected. It kept you alive, emotionally speaking.

I know this personally. Growing up as the son of an alcoholic, I learned to read a room before I learned to read a book. I knew exactly what kind of mood was waiting on the other side of the front door before I turned the knob. Was that a pathology? Or was that a child doing exactly what a child should do: adapting to survive in the relational environment they were given?

This framework takes that adaptation and labels it dysfunction. I think that’s not just inaccurate. I think it’s harmful. It tells people that the part of them that learned to fight for connection (often at great personal cost) is the broken part. And in my experience, that message makes healing harder, not easier.

Modern attachment research supports this. John Bowlby and Mary Ainsworth showed us decades ago that human beings are wired for connection, and that our attachment strategies are shaped by the environments we grow up in. What looks like this pattern is often anxious attachment, a pattern that develops when caregivers are inconsistent or unavailable. It’s not addiction. It’s attachment.

6 Signs You Might Be in a Codependent Pattern

Now, the fact that I reject the label doesn’t mean the patterns aren’t real or that they don’t cause suffering. They absolutely do. Here are six signs that you might be caught in what most people call a codependent dynamic (and what I would call an anxious attachment pattern operating in an unstable relational system).

1. You lose track of your own needs. You know exactly what your partner wants, what triggers them, what soothes them. But when someone asks what you need? Blank. This pattern erases your own signal because, at some point, your needs became noise in a system that only had room for one person’s experience.
2. You feel responsible for your partner’s emotions. Not empathetic toward them. Responsible for them. When they are unhappy, you experience it as your failure. This is one of the hallmarks of the label, but it’s actually a sign that your nervous system learned to treat your partner’s distress as a threat to the attachment bond itself.
3. You have difficulty setting boundaries, or you feel guilty when you do. Boundaries can feel like betrayal when your relational template says that love means total availability. The label would say you’re addicted to approval. I’d say you learned that setting boundaries risked disconnection, and disconnection was the most dangerous thing in your world.
4. You stay in situations that hurt you. Not because you enjoy pain, but because leaving feels like dying. This is the attachment system doing its job. It is designed to keep you bonded even when the bond is painful, because in our evolutionary history, disconnection from the group meant death. The traditional language misses this entirely.
5. You over-function in the relationship. You’re the planner, the fixer, the emotional manager, the one who holds everything together. People slap the label on this. I call it a logical response to being with someone who under-functions. You fill the vacuum because someone has to.
6. Your self-worth is tied to the relationship’s success. If the relationship is good, you’re good. If the relationship is struggling, you’re failing. This is another sign the traditional framework would point to, but it makes perfect sense through the lens of attachment. Your primary relationship is the foundation of your felt safety. Of course its condition affects how you feel about yourself.

If you recognize yourself in these patterns, I want to be clear: nothing is wrong with you. Something happened to you. And now your system is running old software in a new environment.

Codependency and Attachment Theory: What the Research Actually Shows

Here is what the research actually tells us when we move beyond this model and into attachment science. Studies in attachment neuroscience have shown that our attachment style, formed in childhood, profoundly shapes how we behave in adult romantic relationships.

People with anxious attachment (the group most often given this label) show heightened activation in the brain’s threat detection systems when they perceive distance or disconnection from their partner. Their amygdala fires. Cortisol spikes. The nervous system goes into protest mode: calling, checking, pursuing, accommodating. This is not a character flaw. This is a neurobiological response to a perceived threat to the attachment bond.

Meanwhile, people with avoidant attachment (who are rarely labeled codependent, by the way) show a different but equally powerful pattern. They suppress their attachment needs, creating emotional distance as a regulatory strategy. Nobody calls the avoidant person codependent, even though their behavior is also driven by insecure attachment. The double standard tells you something about the bias baked into the concept itself.

This framework essentially pathologizes one side of an insecure attachment dynamic while ignoring the other. It says the pursuer is sick but the withdrawer is just “independent.” That framing is clinically irresponsible, and it’s one of the reasons I push back against the term so hard in my practice.

The Difference Between Codependency and Interdependence

So if the codependency framework isn’t right, what is?

I use a model I call the “Sovereign Us.” It starts with a distinction most people miss: the difference between clinging, withdrawing, and choosing.

Codependency is what happens when two people cling because the ground beneath them is unstable. The system feels like it could collapse at any moment, so both partners grip tighter, lose themselves, and fuse in ways that feel suffocating but necessary. The clinging isn’t the disease. The unstable ground is the disease.

Independence, taken to its extreme, is just as damaging. I’ll get to that in a moment.

Interdependence is what becomes possible when the ground is steady enough for two sovereign selves to lean toward each other without collapsing. This is the goal. Not two people who don’t need each other (that’s avoidance dressed up as health). Not two people who can’t function without each other (that’s what most people mean when they say codependency). But two whole people who choose to build something together, knowing they can stand on their own but preferring not to.

The Sovereign Us means that both partners maintain their individuality while also committing fully to the relationship. It’s the difference between “I can’t live without you” and “I can live without you, and I’m choosing to build this life with you.” Both are love. But only one is sustainable.

Why Hyper-Independence Is Just as Dangerous as Codependency

There’s a quote that floats around therapy circles called the Gestalt Prayer. It goes something like this: “I do my thing and you do your thing. I am not in this world to live up to your expectations, and you are not in this world to live up to mine.”

It sounds enlightened. It sounds healthy. And I think it is catastrophic in an attachment relationship.

Hyper-individualism, the idea that you should be completely self-sufficient and never need anyone, is the shadow side of the codependency conversation. When people learn about this concept, many of them swing hard in the other direction. They build walls. They call it boundaries. They stop attuning to their partner’s needs and call it “doing my own work.” They replace connection with a kind of relational isolationism that looks healthy on Instagram but feels like abandonment to the person they’re in a relationship with.

Here is the truth: you are supposed to need your partner. Not in a desperate, “I’ll die without you” way. But in a real, embodied, mammalian way. We are a pair-bonding species. Our nervous systems are designed to co-regulate. When the idea of codependency gets rebranded as any form of needing your partner, we have lost the plot entirely.

The answer to these patterns is not independence. The answer is earned security. It’s learning to need someone in a way that doesn’t erase you. That’s a skill, not a personality trait. And it can be developed at any age, in any relationship, with the right support.

How to Move from Codependency to Secure Attachment

If you recognize these patterns in your relationship, here is the clinical path I walk with couples in my practice at Empathi.

Step 1: Stop pathologizing yourself. The first thing I do with every client who comes in saying “I’m codependent” is challenge the label. Not the pain underneath it. The label itself. Because as long as you believe your attachment needs are a disease, you will never feel safe enough to explore them. You cannot heal something you’re ashamed of. The label keeps you in shame.

Step 2: Understand your attachment history. Where did you learn that love required self-erasure? Who taught you that your needs were too much? What happened when you expressed anger, sadness, or need as a child? These questions matter more than any checklist you’ll find online. Your current patterns make perfect sense when you see the environment that shaped them.

Step 3: Build awareness of your nervous system. Most of these patterns run on autopilot. You don’t choose to lose yourself in your partner’s crisis. Your nervous system takes over. Learning to notice the activation (the tightness in your chest, the urgency to fix, the inability to focus on anything else) gives you a moment of choice between the trigger and the response.

Step 4: Practice being with discomfort. These behaviors often serve an anxiety-reduction function. When your partner is in distress and you rush to fix it, you’re also soothing your own nervous system. Learning to sit with the discomfort of your partner’s pain without making it your emergency is one of the most important skills in moving toward secure attachment.

Step 5: Work with your partner, not just on yourself. This is where I diverge from a lot of traditional treatment. Most programs focus on the individual. “Fix yourself. Set your boundaries. Detach with love.” I think that approach misses half the picture. Codependency is a relational pattern. It happens between two people. Both people need to be part of the repair. Couples therapy is often the most effective path forward because it addresses the dynamic, not just one person’s contribution to it.

Step 6: Build the Sovereign Us. The end goal is not independence from your partner. It’s interdependence with your partner. Two people who have done enough of their own work to show up as whole selves, and who have built enough trust and safety between them that leaning in doesn’t mean falling over.

What You Can Do Right Now

If you’re reading this and seeing yourself in these patterns, here are three things you can do today.

First, drop the label. You are not codependent. You are a person who learned to love in an environment that required sacrifice. That adaptation served you once. It may not be serving you now. But it was never a disease.

Second, get curious instead of critical. The next time you notice yourself over-functioning, people-pleasing, or losing yourself in your partner’s experience, pause. Instead of “there I go being codependent again,” try “what am I afraid will happen if I don’t do this?” That question will take you somewhere useful. The label never does.

Third, consider couples therapy. Not because you’re broken. Because these patterns are relational, and they heal best in relational contexts. A skilled therapist can help both partners see the dance they’re doing and learn new steps together. At Empathi, this is the core of our work. We don’t treat this as a diagnosis. We treat it as a signal that the attachment system needs repair.

You learned to love this way for a reason. The work is not to stop loving. The work is to build a relationship where you can love fully without disappearing. That’s not recovery from a disease. That’s growing into the secure attachment you deserved all along.
