After an affair: why 'just moving on' doesn’t rebuild trust

When an affair has been discovered, couples can find themselves having the same painful conversation over and over again. One partner may ask questions, seek reassurance, and struggle to understand how this could have happened. The other may be thinking: I’ve apologised. I’ve answered the questions. I can’t change what happened. How will we ever move forward if we keep going back over it? Both can feel completely stuck.

An affair can change your sense of what was real because it doesn’t only damage trust in a partner; it can also shake someone’s understanding of the relationship they thought they had. So, the betrayed partner may start looking back at memories differently. They might start asking: Was that weekend away what I thought it was? Were you messaging them then? When you said you were working late, was that true? What else don’t I know?

Sometimes they begin to question their own judgement too. They may wonder how they didn’t know, whether they missed signs or whether they can trust their instincts again. This is one reason why simply agreeing to “put it behind us” can be so difficult.

Why do the questions keep coming?

For the person who has been betrayed, repeatedly asking questions isn’t necessarily about wanting to punish their partner. Often, they’re trying very hard to make sense of something that has made their world feel suddenly less predictable.

They may find themselves checking their phone, noticing small changes in behaviour, or becoming anxious when their partner is late home. Something that previously wouldn’t have concerned them can suddenly feel threatening. Their mind may be searching for certainty: Am I safe now? Do I know the whole truth? Could this happen again?

Unfortunately, the more reassurance they need, the more overwhelmed the other partner can become. Not knowing what to say to fix things can become increasingly distressing.   They may feel guilt or shame about the pain they’ve caused. They may desperately want to repair the relationship but feel that nothing they do is enough. Eventually, they may become defensive or withdrawn.

It’s not unusual for them to say the following:

• “We’ve already talked about this”
• “I’ve told you everything”
• “You said you wanted us to move forward”

As understandable as that response may be, withdrawing can inadvertently increase the betrayed partner’s anxiety.

If questions are met with defensiveness or avoidance, they may wonder whether there is still something being hidden. And so a painful cycle develops: One partner pursues answers and reassurance. The other retreats from a conversation they feel they can never get right. The more one pursues, the more the other withdraws, and the less safe both people feel.

And rebuilding trust is different from saying sorry. Of course, an apology matters and taking responsibility matters, but trust is rarely restored by one conversation. It is usually rebuilt through what happens afterwards: honesty, consistency, openness and a willingness to tolerate some uncomfortable conversations.

That doesn’t mean the affair needs to dominate the relationship indefinitely. Nor does it mean that every detail is necessarily helpful. But there may need to be space for the hurt to be understood before both partners can genuinely begin to move beyond it.

Over time, the questions may start to change. Instead of only asking “What happened?” a couple may begin to explore:

• What was happening for us before this?
• Where had we stopped talking to one another?
• What do we each need from a relationship now?
• What would help trust begin to grow again?

Understanding what was happening within a relationship is not the same as excusing an affair. The person who made the decision to have an affair remains responsible for that choice. But if a couple decides they want to stay together, understanding their relationship more deeply can help them create something different.

Does couples counselling mean committing to staying together?

No, not necessarily. Sometimes couples arrive for counselling without knowing whether they want to repair their relationship at all. One may desperately want to stay together while the other isn’t sure. Sometimes both are unsure.

Couples counselling shouldn’t be about saving a relationship at any cost. However, it can provide a space where both people can begin to understand what has happened, talk about things that have become almost impossible to discuss at home, and work out what they genuinely want.

For some couples, that leads towards rebuilding. For others, it may lead towards separation. And for many, the answer isn’t immediately clear. Sometimes there's relief in knowing you don’t have to know yet.

People often feel under enormous pressure to make a decision following an affair or betrayal:

• Can I forgive this?
• Will I ever trust them again?
• Should I stay or should I leave?

Those are big questions, and they don’t always need immediate answers. Sometimes the first task is simply to slow things down enough for both people to understand what has happened and what they’re feeling.

Only then can the question gradually shift from asking: How do we get back to how we were? towards something perhaps more useful: What would our relationship need to become if we were going to choose each other again?
