Can a marriage survive an affair?
Yes, often. In the one study that followed couples for five years after couple therapy, 57 per cent of those whose affair was out in the open were still married, and the couples who stayed together reported about the same satisfaction as couples who had never had an affair. Where the affair stayed secret, four couples in five had divorced. The numbers are small — 19 couples — so read them as a direction and not a forecast. The direction is that an affair which is told, owned and worked through is survivable more often than not, and one that stays hidden usually is not. What you both do in the year after matters more than the affair does.
Can a marriage survive an affair? What the numbers say
It is two in the morning, the phone is face down on the duvet, and you have typed the question into a search bar because there is nobody you can ask out loud yet.
Researchers at UCLA and the University of Washington followed 134 married couples who had taken part in a trial of couple therapy, and checked on them for five years after therapy ended. Nineteen of those couples had an affair in the picture. The results were published in 2014 in Couple and Family Psychology:
- Affair revealed (14 couples): 43 per cent divorced, 57 per cent still married.
- Affair kept secret (5 couples): 80 per cent divorced.
- No affair (115 couples): 23 per cent divorced.
The second finding gets quoted less and I think it matters more. Among the couples who stayed married, the ones who had been through an affair reported about the same relationship satisfaction as the ones who had not. They stayed, and by their own account the marriage they stayed in was actually good.
Three cautions before you lean on those figures. Fourteen couples and five couples are small groups, and the authors say so themselves. Every one of these couples was in therapy, so the study says nothing about couples who try to get through it alone. And the authors warn that “disclosure is no assurance of a positive outcome” — more than four in ten of the couples who put the affair on the table still divorced.
The same paper reports one more pattern from earlier studies by this research group. Couples dealing with an affair started therapy in worse shape than other couples, and by twelve months had improved more than the others. A terrible starting point did not predict a terrible ending.
How common is this?
More common than anyone at the school gate will admit. YouGov surveyed 2,000 American adults in September 2022: of those who had ever been in a monogamous relationship, 33 per cent said they had cheated — physically, emotionally or both — and 54 per cent said they had been cheated on. On the narrower question of sex outside a marriage, the General Social Survey, as reported by the Institute for Family Studies, put it at 20 per cent of men and 13 per cent of women. Those are American figures; recent Canadian ones are thin.
Why the secret does more damage than the affair
In the earlier work from the same group, couples with a secret affair “showed gains early in treatment but deteriorated in later portions of therapy.” That is exactly what you would expect. One of you is working on the marriage and the other is working on the marriage while managing a second set of facts. Nothing built on that holds weight for long.
Five couples cannot prove that secrecy causes divorce. It is possible that some marriages were ending anyway, and the affair stayed hidden because nobody saw a reason to tell. But the best-known model of affair repair starts in the same place the data point to: with full disclosure, before anyone is asked to forgive.
| What people assume | What the research points to |
|---|---|
| “An affair means the marriage is over.” | Five years after therapy, 57 per cent of couples with a revealed affair were still married. |
| “Even if we stay, it will never be as good.” | Couples who stayed married reported similar satisfaction whether or not there had been an affair. |
| “The less we talk about it, the faster we heal.” | Couples with a secret affair gained early in therapy, then slid back. Four of the five had divorced by year five. |
| “This only happens in bad marriages.” | A third of people who have been in a monogamous relationship say they have cheated (YouGov, 2022). |
| “Once they have apologised, trust should come back.” | In interviews with couples who did heal, rebuilding trust was the hardest part and the slowest. |
What repair actually involves
John Gottman calls his approach the Trust Revival Method, and the Gottman Institute describes it in three phases. Atone: the partner who had the affair takes full responsibility, stays non-defensive, discloses fully, and offers transparency — phone, calendar, whereabouts — for a time. Attune: the two of you build what amounts to a new relationship, which Gottman grounds in “the desire and the ability to understand and respect your partner's inner world.” Attach: physical intimacy is rebuilt last, slowly, and by talking about it.
A 2023 study in the Journal of Social and Personal Relationships came at it from the other side. Stephen Fife and his colleagues interviewed 16 couples who had stayed together after an affair and described their own healing as meaningful. The couples went through four stages: the revelation, the first reactions, stabilizing, and then revitalizing the relationship. Along the way they named the same handful of tasks — affirming commitment, establishing accountability, communicating deeply, re-establishing trust, and moving from an early, thin forgiveness to a deeper one.
I practise Relational Life Therapy, and Terry Real's institute frames the work in two phases: containment, then transformation. The hurt partner arrives with two questions — “How could you do that?” and “How do I know you won't do it again?” — and both deserve real answers. What the model asks of the partner who strayed is what it calls “realistic remorse”: accountability for the damage, without the collapse into shame that turns the conversation back toward the person who did the hurting.
If you are the one who had the affair
- End it, completely, and say so. Repair cannot start while the other relationship is still open, even a little.
- Answer what you are asked, truthfully. A second discovery three months from now will probably do more harm than the first one did.
- Drop the defence. “I was lonely” may be true and may matter later. Said in the first month, it lands as blame.
- Offer transparency before it is demanded. A phone handed over is worth more than a phone surrendered.
- Expect it to come up again. At dinner, in the car, on an ordinary Tuesday. Each time you stay in the conversation without sighing, you are making a deposit.
If you are the one who was betrayed
You do not have to decide this week. Staying in the house is not the same as forgiving, and agreeing to one counselling session is not the same as agreeing to stay.
The loop of questions and images is common in the first months, and it is not a sign that you are handling this badly. You are allowed to ask what you need to ask. Many therapists suggest asking about facts — who, when, how long, is it over — and to go carefully with the details that will only give the images more to work with.

When it may not be survivable
Some marriages should not survive an affair, and the research does not say otherwise. The signs I would take seriously: the affair is still going on, the lies keep coming out in instalments, there is no remorse, or the partner who strayed has decided the whole thing is your fault. If you are not sure whether either of you wants to try, that is a different question from how to repair, and it has its own short process — I have written about it in should we separate or try counselling first?, and the discernment assessment on this site takes a few minutes.
If you are afraid of how your partner will react — to a disclosure, to a question, to you leaving — your safety comes before the marriage. VictimLinkBC answers at 1-800-563-0808, any hour.
Getting help in Victoria
This is hard to do alone, mostly because the two people who most need a calm conversation are the two least able to have one. Affair recovery counselling gives the truth-telling a container: someone to slow it down, to keep accountability from turning into either grovelling or defence, and to make sure the hurt partner's questions get answered. I see couples in person in Victoria and by secure video anywhere in BC, usually together, sometimes with individual sessions alongside. Fees are here, and the first step is a free 15-minute consult — either of you can book it, with or without the other.
Fifty-seven per cent is not a promise. It is enough to justify finding out.
Common questions
Can a marriage survive an affair?
Often, yes. In a five-year follow-up of couples who had been through couple therapy, 57 per cent of those whose affair had been revealed were still married, and the couples who stayed together reported similar satisfaction to couples with no affair. The study was small, so treat it as a direction and not a guarantee.
What percentage of marriages survive infidelity?
There is no single reliable figure. The best long-term data come from a 2014 study in Couple and Family Psychology: five years after therapy, 57 per cent of couples with a revealed affair were still married, compared with 20 per cent of couples whose affair stayed secret and 77 per cent of couples with no affair. Only 19 couples in the study had an affair, and all of them were in therapy.
Can a marriage ever be as good as it was before the affair?
It can. In the same five-year study, couples who stayed married after an affair reported about the same relationship satisfaction as couples who never had one. Most couples who get there describe a different relationship from the one they had before, with more said out loud.
How long does it take to rebuild trust after an affair?
Longer than either of you wants, and there is no reliable number. In a 2023 interview study of 16 couples who healed after infidelity, rebuilding trust was the hardest and slowest part of the process. Expect months before the worst eases, and judge progress by direction and not by the calendar.
Should I tell my spouse about an affair?
An article cannot make that decision for you. What the research shows is that couples whose affair stayed secret did far worse over five years than couples who worked through it openly, and the Gottman approach to repair starts with full disclosure. How and when you tell matters, and a therapist can help you plan it. If you fear for your safety, call VictimLinkBC at 1-800-563-0808 first.
Is it normal to keep picturing the affair and asking the same questions?
Yes. Intrusive images and repeated questions are very common in the first months after discovery and are not a sign that you are failing to cope. They usually ease as the story is told honestly and trust is rebuilt. If you are having thoughts of harming yourself, call or text 9-8-8 or the Vancouver Island Crisis Line at 1-888-494-3888.
Should we go to counselling together or separately after an affair?
Usually together, sometimes with individual sessions alongside. The repair happens between the two of you, so most of the work is joint. If one of you is not sure about staying at all, a short discernment process comes first.
Do you offer affair recovery counselling in Victoria, BC?
Yes. I work with couples after infidelity in person in Victoria and by secure video anywhere in British Columbia. It starts with a free 15-minute consult, and either partner can book it.
