Why “Just Leave” Misses the Point

What do you think would happen if you told someone your partner had been unfaithful?

Unless you have a particularly thoughtful and empathetic confidante, you’ll probably hear some version of: “You need to leave that sorry excuse for a human being.”

I’m here to validate the heart-wrenching reality that it’s not always that simple. Sometimes it is. Often, it isn’t.

Cheating. Infidelity. Affair. Emotional affair. Physical affair. One-night stand. Years-long relationship. Secret lunches. Drinks after work.

Whatever you call it, whatever happened, whatever was done to you — infidelity is part of human relationships, and almost always has been. I’m a therapist specializing in couples therapy and infidelity recovery, and there is no shortage of couples seeking support after betrayal.

So why would someone who has been deeply hurt even consider staying?

The reasons are as varied as the people involved. But I can say this with certainty: almost every betrayed partner who chooses to try carries some degree of shame for not “just leaving.” That added layer of suffering is understandable. It is also profoundly unhelpful.

Society’s rules tend to be simplistic. They aren’t nuanced. They aren’t creative. They rarely account for the complexity of real relationships. Yet so many of us measure ourselves first against the standards of “they say.”

Who exactly are they, anyway?

Do they know you? Do they know your relationship? Will they live with the consequences of your decision?

I’ll tell you what I know. A significant part of my job involves helping people untangle the damage caused not only by betrayal itself, but by the noise surrounding it. And nowhere does that noise get louder than after infidelity.

Consider Joan and Joe — not their real names.

Joan picked up Joe’s phone and saw a text from a contact saved as “Samantha, Client.”

“I miss you. I can’t wait to see you.

Call me as soon as you can — and please try to sleep alone tonight.”

Joan’s stomach dropped.

She demanded to see the rest of the messages. Most had been deleted, but enough remained to reveal ten days of affection, flirtation, intimacy, and sexual content. Eventually, Joe admitted the truth: a six-month affair.

Joan told him to leave for a few days. But they also had children asking where their father was. Her heartbreak mattered enormously — but it wasn’t the only reality in that home. After several days, she let him come home while she tried to determine what to do next.

Everyone she told had an opinion.

Some felt personally outraged by Joe’s behavior. Some were shocked. Others genuinely believed they were empowering Joan by insisting she deserved better. But the outside commentary often created more confusion than clarity.

Because here’s what was also true:

Joan loved Joe.

And — this is the part that often surprises people — she still believed he was a good person.

According to the work of John Gottman and Julie Gottman, this belief matters enormously. One of the strongest predictors of successful reconciliation after infidelity is whether the betrayed partner still experiences the unfaithful partner as fundamentally good .

If the betrayer has been or becomes an irredeemable villain in the betrayed partner’s mind, sustaining the vulnerability and effort required for repair becomes extraordinarily difficult.

Recovery unfolds in stages — and those stages often overlap.

First, the crisis must be held.

Joan’s heartbreak, rage, confusion, grief, resentment — all of it needs space. And Joe must be willing to sit with the impact of what he has done. Not once. Not twice. Repeatedly.

Only then can rebuilding slowly begin.

Rebuilding begins in miniscule steps.  Over shared meals. During bedtime routines with the kids. In quiet conversations late at night. In hundreds of tiny interactions where Joan is unconsciously scanning Joe’s words, tone, consistency, and actions for evidence: evidence of remorse, evidence of honesty, evidence that Joe is the good person she thinks he is and that she is making an acceptable choice.

But healing is never linear.

One night, Joan sits beside Joe on the couch. The next, she runs from the room in tears — not because of what is happening in that moment, but because of what already happened.

That is the reality of staying after betrayal.

Decisions like these carry lifelong implications. Rarely are they made in absolutes. More often, they emerge slowly through uncertainty, ambivalence, memory, hope, grief, attachment, fear, love, practicality, and pain — all existing at the same time.

The advice of outsiders, however well-intentioned, comes from people who do not have to live inside the outcome.  Their black and white feedback blurs the color that fills every couple’s life.

True support for someone like Joan is not about pushing them toward a door marked exit. It is about helping them honestly process the full reality of what they know: the good, the bad, the unbearable, and everything in between.
