You are sitting on the edge of your bed at half past midnight. Downstairs the dishwasher is running. Upstairs, your children are asleep, breathing that slow deep sleep only children have. And somewhere in the last week, or the last hour, the floor of your marriage cracked open. Either you found out, or they found out, or the two of you have been staring at each other across the kitchen island for days trying to work out what in God’s name you tell the kids.
You have typed some version of “telling children about affair” into a search bar. You have found lists. Age-appropriate scripts. Bullet points about not oversharing. Warnings not to make the child a confidant. You closed most of the tabs because they felt sterile, and because none of them touched the actual weight sitting on your chest right now, which is not really about words at all. It is about the fact that the two people who make up your children’s entire sense that the world is safe are not okay, and you are trying to work out how to say that without breaking them.
I want to slow you down before you draft a single sentence to say to your kids. Because the conversation you are preparing for is not, in the way you think, an information transfer. It is a nervous system event. And if you get the nervous system part wrong, no script on earth will save it.
The Thing Your Children Already Know
Which pattern is running your relationship?
Take the free three minute quiz and meet the creature behind the cycle you keep getting stuck in.
Here is what almost every parent in this moment gets wrong. They think the disclosure conversation is the beginning. It isn’t. Your children’s bodies have been reading the emotional weather of your home for weeks, maybe months, maybe years. They have registered the slammed doors, the tight jaw at breakfast, the whispered phone call that stopped when they walked in, the specific quality of silence between the two of you at dinner.
Children do not read our words. They read our nervous systems.
Their small bodies have already logged all of it on what I think of as a somatic ledger, the biological record every child keeps of what it actually feels like to live in this family. Long before language, that ledger is running. By the time you sit down to “tell them,” the ledger is already full of data. The question is not whether they will find out something is wrong. They found out. The question is whether the adults in the room will now confirm what their bodies already know, or gaslight them into distrusting their own senses.
That second option is the one most families accidentally pick. It is presented as protection. It is not protection. It is a small child watching their mother cry in the bathroom, hearing “Mommy is fine, sweetheart,” and slowly learning that their eyes and ears lie to them. Grounded in attachment theory, we know that a child’s capacity for self-regulation grows out of accurate co-regulation with a trustworthy caregiver. If the caregiver is systematically denying reality the child is perceiving, the child does not get regulated. They get confused about what is real. That confusion follows them into every adult relationship they will ever have.
So the first shift I need you to make, before you say anything to your children, is this. You are not deciding whether to introduce difficult information into their world. The difficult information is already in their world. You are deciding whether to meet them in it.

Before Any Conversation With the Kids: The Parental Alliance Comes First
Seventeen years of sitting with couples in exactly this room, and I can tell you: the single biggest predictor of how your children come through this is not the words you choose. It is whether the two of you can stand next to each other in the same room, at the same time, and be, for one hour, on the same team about them.
I call this the Sovereign Us of Parents. It has nothing to do with staying married. It has nothing to do with forgiveness. It has nothing to do with whether either of you can stand the sight of the other by the end of this year. It is a functional, non-negotiable, non-romantic alliance around one job: your children need a floor. You are the floor. Even if the marriage is in ruins, the floor cannot be.
Almost every couple I have watched try to talk to their kids without doing this internal work first ends up leaking. The betrayed partner leaks fury through their eyes even while their mouth says “we both love you.” The partner who had the affair leaks shame and defensiveness. The child sits between them and registers, correctly, that the two people who are supposed to be holding them are actually still holding knives.
So before you sit them down, you have to sit down. The two of you. Alone. And do a piece of work most couples skip because it is unbearable.
Here is what that work looks like. It is not a conversation about who did what. It is a conversation about the flashlight. The betrayed partner’s flashlight is pointed at the story of the other. Every ounce of attention is on what he did, what she did, who they were with, how long, how much. Understandable. Necessary, even, at some point. But when the flashlight lives out there in the courtroom against your partner, you have no attention left for what is happening inside your own body, which is where the wobble your children will feel actually lives.
Turning the flashlight around, back toward your own trembling insides, is the first move. Not because your partner is off the hook. Because your children need at least one adult in the room who is in contact with themselves before you speak to them.
I have written more about the underlying architecture in what secure functioning actually looks like, and much of that architecture applies here even when the romantic relationship is over. The couple bubble can dissolve. The parental bubble cannot.
What Actually Happens in the Room: A Composite From Practice
Let me tell you about a couple, and I am going to change every identifying detail. Call them Niamh and Ciaran. She is a cardiologist. He runs a software company. They had been in the freeze for three weeks by the time they got to my office, trying to work out how to tell their two children, ages nine and thirteen.
Niamh spent the first session with her arms crossed high, jaw tight, listing evidence. She had been searching for scripts about telling children about affair conversations at three in the morning for two weeks. Ciaran sat flat, cold, rigid, arms at his sides, complying with everything she said like a robot, agreeing to whatever timeline she wanted, saying almost nothing of his own. From the outside, she looked like the wound and he looked like the wall.
I did the thing I always do, which is turn the flashlight off the content. What’s happening in your chest right now, Ciaran? Long silence. Then: it goes freezing cold. My throat closes up. Every time she looks at me, I feel like a little kid failing a test he cannot pass. I go quiet because I do not know how to be here without making it worse.
Niamh’s arms uncrossed. Not because she forgave him. Because she saw, for the first time in weeks, the frightened, wobbly person underneath the wall. And in that moment she was able to say, I have been getting loud because I felt completely alone in the dark. Every time you go flat, I feel like I am disappearing.
They were not fixing the marriage in that moment. That work was going to take years, or it wasn’t going to happen at all. But something else happened. They stopped being two suffering people in separate bubbles and started being two parents who could feel their own pain and each other’s pain at the same time. That is what I call Empathy Cubed. And that is the state you need to be in, at least for an hour, before you talk to your children. Because that is the state your children will feel, no matter what words come out of your mouths.

What to Actually Say (And What Not To)
Now, and only now, we can talk about the conversation itself.
Say it together, in the same room, sitting near each other. Not because you are performing a united front. Because your children’s bodies need to see that the two of you can occupy the same space without the room catching fire. That is the whole message. The words are secondary to the fact that the two of you are, for this hour, functionally together.
Say less than you think. Children need enough truth to make sense of what they have already been feeling. They do not need the details of the affair. They do not need to know who, how many times, in what hotel, discovered how. Sharing those details is not honesty. It is leakage. It is you outsourcing your dysregulation to a child who cannot metabolize it and will spend seventeen years trying.
The frame I use is simple, and it names three things.
One, name the reality their body has already been reading. Something has been hard between us. You have probably felt it. We are sorry we didn’t talk to you about it sooner.
Two, name what happened, at the level of a nine-year-old or a fifteen-year-old, without making one parent the villain and the other the saint. Something happened in our relationship that broke trust between us. We are working out what happens next.
Three, and this is the one almost every family gets wrong, name what is not their job. This is not something you caused. This is not something you can fix. Our job is to be your mom and your dad. That job does not change. Whatever happens between the two of us as a couple, we are both here.
Then stop talking. And this is the hardest part. Let them have whatever reaction they have. Rage. Silence. A shrug and a request to go play. A question you cannot answer. All of it is valid. None of it is a performance review of how well you delivered the script. Your job in that moment is not to manage their reaction. It is to be steady enough that their reaction can happen in the room instead of being swallowed and stored.
If a child asks a question you cannot answer honestly without leaking, it is okay to say: that is a question for grownups. What I can tell you is that we both love you and neither of us is going anywhere as your parent.

The Trap Almost Every Family Falls Into
There is a specific betrayal that happens in families in the months after disclosure that is, in my clinical experience, more damaging to children than the affair itself. It is the moment a parent, usually in agony and usually not meaning to, turns a child into a confidant.
It looks like the mother whispering to her fourteen-year-old daughter what her father actually did. It looks like the father telling his eleven-year-old son that his mother was cold for years, and can he blame him. It looks like a parent, crying at the kitchen table, saying to the child sat with them, “I have no one else to talk to.”
I understand where it comes from. The isolation of the betrayed partner is total. The shame of the partner who strayed is unbearable. The child is right there, and they seem to understand, and it feels like relief.
It is not relief. It is what I think of as the sibling society leaking into the family. It is the parent, in a state of arrested regulation, reaching to their child the way a peer would reach to another peer. It flips the direction of care that a child’s whole developing self depends on. Children are not equipped, biologically or developmentally, to hold the weight of an adult’s romantic devastation. When they are asked to, they do it, because they love you. And they pay for it for the rest of their lives with a pattern of over-functioning, hyper-vigilance, and a persistent sense that other people’s emotions are their responsibility to manage.
Your child is not your confidant. Not now. Not later. Not when they are twenty-five. The person you talk to about the affair is your therapist, your closest friend, your sister, your priest, your Figlet. Not your child. This one line, held for the next five years, will do more to protect them than any script.
If you want a broader map of how relational alarm bells fire in children who grow up in these systems, I write about it in attachment styles and how your love pattern is shaped.
What Repair Actually Looks Like Over Time
The conversation is not the event. The conversation is one moment in a long, slow, unglamorous process of your children watching the two of you demonstrate, over months and years, whether adults can be trusted.
The good news, and I mean this clinically, is that children are not primarily damaged by hard things happening. They are damaged by hard things happening in the presence of adults who cannot metabolize them. A child who witnesses their parents go through something devastating and slowly, imperfectly, repair, learns something extraordinary. They learn that ruptures do not end everything. They learn that adults can be honest about being wounded. They learn that love and rage and grief can all be in the same room without the roof falling in. That is not damage. That is one of the most important educations a child can receive.
What sabotages this is the pretense of unruptured functioning. The forced Sunday dinners where everyone pretends nothing happened. The gritted-teeth smiles at the school pickup. The performance of a family that is fine. Children read all of it and learn that grown-ups lie about the biggest things.
What builds it is small, repeated, honest micro-moments. A parent saying, “I was short with you this morning. That wasn’t about you. I’m having a hard week and I’m sorry.” A parent asking, “How has this been for you? You don’t have to answer, I just want you to know I’m asking.” A parent, when the child rages, staying in the room instead of leaving, holding the ground, saying, “I hear you. You are allowed to be furious. I’m still here.”
These are not scripts. They are the outward form of a nervous system that has done its own work first. Which is why I keep circling back to the same place: what you say to your children is downstream of what the two of you have or have not managed to do with your own dysregulation.
I have written elsewhere about how to get a partner who has gone silent to open up again, and the same architecture applies inside a family in crisis: safety first, connection second, and only then does anything a child hears actually land.
Common Questions
At what age should you tell a child about a parent’s affair?
There is no clean age cutoff. Younger children need less content and more reassurance about who is picking them up from school and where they are sleeping. Older children need enough of the truth to make sense of what they have already sensed. The wrong question is what age. The right question is: what is the smallest amount of truth that closes the gap between what their body has been feeling and what they are being told?
Should we tell the children together or separately?
Together, in the same room, in the same conversation, if you can manage even one hour of the parental alliance I described above. Doing it separately almost guarantees two competing narratives, and children then have to work out which parent to believe, which is a burden they should never have to carry. If safety concerns make a joint conversation impossible, that is a different situation and needs individual clinical guidance.
What if my child asks who cheated?
You can name it factually without editorializing. “Dad had a relationship with someone outside our marriage” is different from “your father betrayed us.” The first is information. The second is recruitment. Recruitment turns your child into your ally against the other parent, which damages them and damages their long-term relationship with both of you. Name the fact. Do not draft them into your side.
Will telling my child about the affair traumatize them?
Not by itself. What traumatizes children is not honest, well-held disclosure. What traumatizes children is chronic dysregulation dressed up in denial, or being made to carry adult emotional weight they cannot metabolize. A brief, honest, co-regulated conversation followed by months of steady parental presence is not trauma. It is repair. The trauma pattern is the opposite: no acknowledgment, ongoing tension, and a child left alone with a reality no adult will confirm.
What if we cannot even be in the same room without fighting?
Then that is the work, and it comes before the conversation with the kids, not after. Get a therapist. Get a mediator. Get an experienced friend to sit in the room with you. Do not talk to your children until the two of you can, for one hour, occupy the same space and hold the same message. If that hour is genuinely impossible, then you tell them one at a time with a shared script that neither of you deviates from, and you keep working on the alliance in parallel.
This is not a you problem or a them problem
“When two insecurely attached people interact, their protector strategies collide to form a negative feedback loop I call the Waltz of Pain. Your protector meets your partner’s protector. Their protector meets yours. Two childhood strategies collide, and the relationship becomes a reenactment of wounds neither partner caused.”
“Neither partner is the villain. They are two younger selves inside adult bodies trying to stay safe in the only ways they once knew.”

Bring what surfaced here into a real conversation. Figlet coaches you through it, grounded in Figs O’Sullivan’s work, LMFT. Free to start.
Your children’s bodies already know something happened. The question was never whether to tell them. The question is whether the two of you can become steady enough, for one hour, to meet them in the reality they are already living in. Do that work first. Then say the fewest true words you can. Then stay in the room.
