When You Have to Co-Parent With the Person Who Hurt You

There is a version of co-parenting advice that assumes the hardest part is learning to communicate better.

Keep messages brief. Stay respectful. Put the children first. Let go of the past.

All of this can be useful advice. But it can feel strangely inadequate when the person you are expected to communicate calmly with is also the person who hurt you profoundly.

Perhaps there was an affair or another significant betrayal. Perhaps there were months or years of deception. Perhaps what happened after the separation became as painful as the separation itself. You may have been lied to repeatedly, had your understanding of events disputed, or encountered a level of coldness or cruelty from someone you once trusted completely.

And perhaps none of it was ever meaningfully acknowledged.

The intimate relationship may have ended, but if you have children together, contact with that person has not. You may still need to discuss school, medical appointments, handovers, holidays and the hundreds of ordinary decisions involved in raising a child.

That creates a psychological problem that ordinary co-parenting advice does not always capture.

The relationship can end without the injury being repaired

Ending a relationship and repairing what happened within it are different processes.

A relationship can be legally, practically and emotionally over while significant injuries from it remain unresolved. Separation does not establish the truth about disputed events. It does not make deception disappear. It does not create an apology that was never given, acknowledgement that never occurred or accountability that was never taken.

This matters because people are sometimes told that continued difficulty interacting with an ex-partner means they have not “moved on.”

But moving forward and becoming comfortable with someone again are not the same thing.

You can accept that the relationship is finished. You can build a new life. You can stop wanting reconciliation. You can genuinely support your child's relationship with their other parent.

And still not want a close relationship with that person yourself.

Acceptance means recognising the relationship as it is. Reconciliation means rebuilding the relationship. The first does not require the second.

This distinction becomes especially important when there has been betrayal without repair.

The message may be ordinary. The history isn't.

One of the peculiar features of co-parenting after a painful separation is how mundane the contact can become.

Can you bring her school shoes tomorrow?

Swimming has been moved to Saturday.

What time are you dropping him off?

Viewed in isolation, there is nothing particularly difficult about these messages.

But people do not experience communication in isolation. We experience it in context.

The same name appearing on your phone may once have been associated with intimacy, family and safety. Later, it may have become associated with discovering information, questioning what was true, conflict, denial, rejection or humiliation.

Through repeated experience, contact itself can become associated with threat, conflict or emotional pain. A completely ordinary message can therefore produce an emotional or physiological reaction that seems disproportionate to the words on the screen.

The reaction may not really be about school shoes.

It may be about who sent the message and everything communication with that person has come to represent.

Understanding this does not mean every emotional reaction should determine what happens next. But it helps explain why “just communicate normally” can be considerably harder than it sounds.

Betrayal without acknowledgement creates another problem

There is a particular difficulty when two people continue parenting while holding fundamentally different accounts of what happened between them.

One person may understand the end of the relationship as involving serious betrayal or sustained deception. The other may understand events very differently, deny important parts of that account, minimise what occurred or simply refuse to discuss it.

The result is not merely disagreement about the past. There may be no shared account of something that fundamentally changed the relationship.

For the injured person, ordinary friendliness can then carry an unexpected psychological cost. The difficulty may not be that they are incapable of being civil. It may be that behaving as though the relationship is uncomplicated requires them to suppress something they regard as profoundly important and unresolved.

This can be particularly difficult when the injury involved repeated denial or conflicting accounts of what occurred. Each pleasant interaction can seem to carry an implicit proposition:

We are going to relate to each other as though none of this needs to be acknowledged.

Some people eventually become comfortable doing that. Others experience it as overriding their own reality in order to maintain the appearance of an amicable relationship.

They may not want to keep arguing about the past.

They may not be seeking revenge.

They may have stopped expecting an apology altogether.

They may simply no longer be willing to abandon their own understanding of what happened in order to make the relationship look comfortable from the outside.

Civility can still be possible.

Pretending is not always necessary.

“Focus on the children” does not require ignoring yourself

Few pieces of separation advice are repeated more often than put the children first.

It is an important principle. But it can sometimes be interpreted as requiring one parent to absorb almost unlimited emotional discomfort in the name of successful co-parenting.

Putting your child first does not necessarily mean attending every event together, having friendly conversations at handover, sharing family occasions or maintaining an emotionally open relationship with your former partner.

Sometimes less contact creates better parenting.

If repeated direct interaction leaves a parent distressed, angry, preoccupied or emotionally depleted for hours afterwards, reducing unnecessary contact may allow them to be more available to their child.

The relevant question is not simply:

How much contact can we maintain?

It may be:

What structure allows us to parent reliably while creating the least unnecessary conflict and emotional cost?

Those are very different questions.

A boundary is not the same as punishment

This distinction becomes particularly important after a painful separation.

A boundary says:

This is the level of contact I can participate in while remaining psychologically well and parenting effectively.

Punishment says:

I want to cause you distress or deprive you of something because of what you did.

From the outside, the behaviours can occasionally look similar. Someone may decline unnecessary conversations, avoid shared social situations, prefer written communication or establish firm rules around when and how contact occurs.

The purpose matters.

It is entirely possible to protect and encourage your child's relationship with their other parent while choosing not to maintain a personal relationship with that parent yourself.

You can communicate important information. You can make parenting arrangements. You can respond when something concerns your child. You can be flexible when your child genuinely needs it. You can be dependable.

None of those things require friendship.

And protecting a child's relationship with their other parent does not require giving that parent unrestricted relational access to you.

Communication does not require a relationship

This may be the most useful distinction of all.

Separated parents need a way to exchange information about their children.

They do not necessarily need an ongoing interpersonal relationship beyond what parenting requires.

When trust remains intact, direct communication may be easy. Some separated parents can comfortably talk, attend events together, share photographs and occasionally help one another. When that develops naturally and works for everyone involved, it can be valuable.

But it should not become the standard against which every separated family is judged.

Where trust has broken down or direct interaction repeatedly creates distress or conflict, a more structured communication arrangement may work better. Situations involving coercion, threats or family violence require additional safety considerations and may need specialist advice.

For other families, the solution may simply be to make communication narrower, more predictable and more practical.

Written communication might replace phone calls. Messages might be limited to matters concerning the children. Handover arrangements can become predictable. Expectations about response times can be established. Unnecessary conversational exchanges can disappear.

The goal changes.

Instead of trying to repair the relationship sufficiently to make communication work, you build a communication system that does not require a functioning relationship in the first place.

The parenting information still gets through. The relationship no longer has to carry it.

Reducing contact does not necessarily mean you haven't healed

There is an appealing cultural idea that complete healing eventually produces indifference.

One day, perhaps, you should be able to sit beside the person who betrayed you, chat pleasantly and feel nothing.

Some people reach that point.

Others do not.

Healing does not have to be measured by how much access you can tolerate giving someone who hurt you.

Sometimes healing means no longer arguing about the past. Sometimes it means abandoning the hope that the other person will eventually understand. Sometimes it means recognising that a particular relationship remains psychologically costly and organising your life accordingly.

There is an important distinction here.

You can stop seeking acknowledgement without deciding that acknowledgement was unnecessary.

You can stop pursuing repair without pretending repair occurred.

You can accept that another person may never understand your experience without adopting their version of it yourself.

And you can move forward without restoring a kind of relationship that no longer feels healthy.

Your child does not need you to erase what happened

Children should not be recruited into adult grievances.

They should not be asked to take sides, carry messages between households, provide information about the other parent or reassure a parent about what happened in the adult relationship.

Protecting children from that burden matters.

But protecting a child from adult conflict is different from requiring a parent to erase their own experience.

You do not need to convince your child that the other parent is bad in order to honour the fact that your own experience with that person was painful.

Two things can be true at once:

Your child can be free to love their other parent.

And you can decide what relationship, if any, you are able to have with that person yourself.

Those positions are not contradictory.

In some families, maintaining that distinction may actually protect the child. They are allowed to have their relationship with each parent without becoming responsible for repairing the relationship between the parents.

Sometimes the goal is simply a better system

After a difficult separation, enormous energy can be spent trying to achieve the “right” co-parenting relationship.

Perhaps the more useful goal is smaller.

Make the system work.

Make important information easy to exchange. Reduce opportunities for unnecessary conflict. Keep children out of the communication pathway. Create predictable arrangements. Remove emotional labour where it serves no parenting purpose.

And, where possible, make communication boring.

Not intimate. Not hostile. Not loaded with attempts to resolve the past.

Just functional.

For some separated families, one of the most useful changes is effectively to remove the relationship from the communication pathway. Necessary information can still move between parents without requiring repeated emotional engagement between two people whose relationship is no longer safe, trusting or mutually understood.

That is not the idealised version of co-parenting often presented after separation.

But successful co-parenting should not be measured by whether two former partners can convincingly look like friends.

It should be measured by whether their children are cared for, whether important information reaches the people who need it, whether conflict is kept away from the child and whether the parenting arrangement can function sustainably.

The person who hurt you may remain your child's parent for the rest of your life. That fact can require coordination.

It does not automatically require reconciliation.

Successful co-parenting does not always require two people to repair their relationship. Sometimes it requires building a structure that no longer depends on the relationship being repaired.
