They want to come back.
Maybe they are crying on the phone. Maybe they are sitting in the car outside, or sending long messages at midnight about how they finally understand everything.
And you are standing in your own kitchen with two voices in your head.
One says: you would have to be insane to let them back in.
The other says: but I miss them, and we built a life, and what if this is the moment that changes them?
Your friends have opinions. Your mother has opinions. The internet has a slogan: once a cheater, always a cheater.
Most advice picks a team. Leave immediately and respect yourself, or forgive and fight for your family. Both are simple. Neither one has met your partner, or you.
The question is not whether cheaters deserve a second chance.
The question is whether this person, right now, has done what makes a second chance safe to give.
Below: the 7 tests that actually answer that, what the research on repeat cheating really says, and a 30-day way to make the decision without panic making it for you.

Here is the direct answer.
Take someone back only when the behavior has changed and the choice is really yours. Work through these seven tests honestly, and count what you have seen, not what you were told.
It is over, completely – No contact, no "just friends", no loose ends. You can verify this because they tell you things before you ask.
They told the truth without being cornered – Did they confess, or were they caught? If caught, did the whole story come out, or did it arrive in pieces?
They own it without a "but" – "I cheated, and that was my choice" is a full sentence. "I cheated, but you had stopped paying attention" is a negotiation.
They can sit in your pain – When you cry or rage, do they stay in the room? Or do they collapse, defend, or ask how long this will go on?
They are doing work you did not assign – They booked the therapist. They read the book. They looked at why this happened in their own history.
You can ask anything – The topic is open. You are not punished for bringing it up on a Tuesday when things were going well.
You want them, not just the absence of pain – Picture the relationship in three years with this history inside it. Is that a life you want, or are you trying to stop tonight from hurting?
Here is a quick way to score it.
| Test | Green light | Red flag |
|---|---|---|
| Contact | Ended, and you know how | "It is complicated" or a shared workplace with no plan |
| Truth | One consistent story | New details keep surfacing |
| Ownership | No excuses | Your flaws appear in their apology |
| Effort | They lead the repair | You are running the recovery alone |
| Pressure | They accept your timeline | "When will you get over this?" |
| Pattern | One episode, by every available fact | Multiple partners or years of deception |
If most of your rows sit on the right, you have your answer for today, even if it is hard to look at. If you are not sure how you got here or what has changed, a relationship assessment can help turn the fog into something you can actually see.
What the research says about whether cheaters cheat again
The slogan says once a cheater, always a cheater. The data says something more useful.
Researchers at the University of Denver followed people from one relationship into the next. As Scott Stanley summarized the study, those who were unfaithful in one relationship had three times the odds of being unfaithful in the next. Of those who reported cheating in the first relationship, 45% reported doing so in the second, compared with 18% of those who had not.
So the risk is real.
And the same data refuses the slogan. Stanley points out that a person who cheated was not destined to do it again. Slightly more people who cheated in the first relationship did not report cheating in the second.
Here is the caveat almost nobody mentions. That study tracked people moving into a new relationship, and the data is self-reported. It does not measure what happens when a couple stays and repairs. It cannot tell you about your partner, after this discovery, with you.
So history raises the odds. It does not write the ending. For more on when a pattern has become a character problem, read about the serial cheater.
What about people who stayed? One interview study of 11 injured partners asked why they chose to remain. They talked about the length of the relationship and their shared history, about seeing their partner as trustworthy before this, and about the strength of what they had. Participants were willing to stay when they believed the affair was a single occurrence.
It is a small qualitative study, so it describes reasons and does not predict outcomes. But it shows something honest. People who stay tend to weigh the whole relationship, not only the worst thing that happened in it.
The authors also name a pressure you may recognize: there is often pressure on the injured partner to forgive so the relationship can move forward. You are allowed to refuse that pressure.
Why you can't trust the first two weeks of remorse
The first days after discovery are a terrible time to judge anyone, including yourself.
Their remorse may be genuine. It may also be panic about losing the house, the kids, their reputation or you. From the outside, those can look identical. Both come with tears.
Your own state is no better. There can be a strange surge of closeness after discovery, a sudden hunger for reassurance, a feeling of they finally see me. Plenty of people mistake that surge for repair. If you are spinning through replay loops, read about overthinking after being cheated on, because a mind doing that is in no shape to sign anything.
Think about how a good investor handles a stock that just crashed.
The sunk cost fallacy is the pull to keep putting money in because of what you already spent. You would never buy that stock fresh today, but you hold it because selling makes the loss real. Relationships do this too. We have eleven years in this. That is true, and those years are gone either way. The only real question is whether the next eleven are a good investment.
Call this the Fresh Money Test.
Imagine you met this person today with all the facts you now have. The good years, the kindness, the betrayal, how they acted when it came out. Would you put fresh money in?
Sometimes the answer is yes. A long record of kindness counts, and so does what they have done since. Sometimes the answer is no, and the only thing keeping you there is the money you already spent.
Either answer is more useful than the slogan.
There are 3 ways people decide, and only one holds up
The Sprinter lets them back in within days because the pain of being apart is unbearable. It feels like relief. A few months later, nothing has been addressed, and the betrayal is still in the house with nowhere to go.
The Judge decides on principle before any facts arrive. Sometimes that is exactly right, particularly when there is a long pattern. Sometimes it is a way of escaping the grief of a harder decision.
The Auditor slows down. They do not trust the tears or the rage. They collect behavior over time, ask direct questions and let the evidence come in before they rule.
But what if I wait and they give up?
Then you have learned something valuable. Someone who cannot tolerate a few weeks of uncertainty, after doing this to you, was not going to do the long work of repair. The Gottman Institute's guide on reviving trust after an affair says there is no specific time frame for the process. A partner who is serious will not demand one.
How to decide whether to take them back in 30 days
So what do you actually do with this?
Here is the 30-Day Auditor Plan. You can do it living together or apart, whichever is safe and practical.
Week 1: stabilize
Announce the pause. You are not ruling yet.
"I am not making a decision this week. I need time and honesty from you. Please do not ask me for an answer."
Pick one or two safe people. Injured partners in that interview study were selective about who they told, and judgment from others shaped who they reached out to. So choose someone who can listen without pushing you toward a verdict.
Book a therapist for you. Not for the relationship. For you. Whatever you decide, you will need somewhere to think out loud.
Week 2: gather facts
Ask your questions in one sitting. Write them down first. Who, how long, what was said about you, and is it over.
Write down the answers and date them. You are building a record so that you can compare it with later versions. A story that stays the same is a good sign.
Week 3: watch behavior
Say nothing and observe. Do they keep their word when you are not testing them? Do they lead the repair? Do they take your bad days without complaint?
Score the 7 tests again. Compare with your first attempt, and count only what you have witnessed.
Week 4: decide your next step
Your decision does not have to be final. You have three honest options.
Yes, conditionally. They come back with clear terms: no contact, couples therapy with someone experienced in infidelity, and full honesty. If so, staying after cheating covers what comes next.
Not yet. You extend the pause by a set period, and you say what you need to see during it.
No. That is a complete answer, and you do not owe them an appeal. When to walk away after infidelity can help you finish that thought.
Take the assessment again at the end if it helps you see what shifted. It will not decide for you, and it cannot tell you what anyone did.
One firm line. If your partner threatens you, monitors you, frightens you, or makes staying feel unsafe, this plan does not apply. Contact the National Domestic Violence Hotline at 1-800-799-7233 or thehotline.org before you take any other step.

Take the Free Assessment →Forgiving them and taking them back are two different decisions
Most people treat these as one question. They are not.
You can forgive someone and never live with them again. You can let someone back in and still be working on forgiveness for years. If forgiveness is the part you are stuck on, read how to forgive an unfaithful husband, because it applies well beyond husbands.
Letting someone back in is a decision about the future, and it rests on what they do next.
Stop asking whether they deserve another chance.
Ask whether you can build a life you respect from here.

Frequently Asked Questions
Should you take back a cheater?
Only if the cheating has fully stopped, they have taken responsibility without blaming you, they answer your questions honestly, they are doing the repair work, and you actually want the relationship rather than fearing being alone. If several of those are missing, the honest answer is not yet, and possibly not at all.
Do cheaters cheat again if you take them back?
Some do and many do not. One study that followed people across relationships found prior cheating tripled the odds of cheating in the next relationship, yet slightly more than half of those who cheated did not report doing it again. That study looked at a new relationship, so it cannot predict your partner with you.
Is taking back a cheater weak?
No. Staying can be a clear-eyed decision and leaving can be too. What matters is whether you chose with full information and without pressure. The weak version of either choice is the one made to escape a feeling, whether that feeling is loneliness, shame or rage.
How long should I wait before taking a cheater back?
There is no research-backed number. Give yourself enough time to get past the first shock and to watch behavior rather than promises. Many people find at least a few weeks of space useful, and you can extend that as long as you need.
What if they cheated more than once?
A repeated pattern deserves far more caution than a single episode, because the promise has already been tested and failed. Ask what is different this time in actions, not words. Injured partners in one study were more willing to stay when they believed the affair was a one-time event.
