Mistakes to Avoid After Discovering Cheating in Marriage

When you first discover that your partner has had an affair or been unfaithful in your marriage, you may want to throw them out immediately. You feel violated, betrayed, angry, confused, and, most of all, hurt. Questions flood your mind: How could they lie to you? How could they do this to you and the children? Why didn’t you notice sooner? How could this happen when you thought everything was going well?

While your initial reaction might be to ask them to leave, that feeling often subsides. The two of you may then talk it over or assess the situation, leading you to consider whether it's possible to work things out. Were there events that contributed to the affair? What could both of you do differently? If both partners are willing to give the marriage another chance and commit to the work required to prevent further infidelity and rebuild trust, there are specific behaviors you should avoid.

Many therapists who specialize in helping couples recover from infidelity offer guidelines on what not to do after an affair is revealed. I’ve compiled some of the most important recommendations to help prevent further damage to your marriage. In some cases, the emotional destruction may be too severe to repair the relationship. However, roughly half of marriages can survive and improve after infidelity. Seeking help from a mental health professional and following these guidelines can increase the chances of saving your marriage.

1. Do not tell anyone, including family and friends. Protecting your marriage’s privacy is crucial. When the affair is first exposed, resist the urge to share the news with others. This isn’t about denying what happened or avoiding embarrassment. It’s about giving yourself time and space to process the shock and confusion in a safe environment with your spouse. Everyone will have opinions, and they may change based on your decisions. If you’re trying to salvage the marriage, it’s essential that both of you understand what happened and face the consequences together. The partner who cheated must take responsibility, make amends, and help create firm boundaries to protect the relationship as it heals.

2. Stay off social media. When you're hurt and angry, it might feel tempting to vent on social media. However, this can negatively impact your mental health and invite unnecessary drama. Anything posted online lives forever, and if you choose to work things out, others will continue to remind you of what you said. It's far better to manage your emotions privately and communicate your feelings directly to your partner. If you need to vent, this is an excellent time to seek support from a therapist.

3. Avoid blaming or obsessing over the person your partner cheated with. Your partner is the one responsible for the betrayal. It doesn’t matter who the other person is or what they did—ultimately, your partner chose to violate your trust. Blaming the other person, comparing yourself to them, or seeking vengeance only causes more harm. If the person knowingly engaged with a married partner, they have their own character flaws, but that’s irrelevant to your healing process. Let it go and focus on the core issue: your relationship.

4. Don’t make rash decisions for at least one year after the disclosure. Avoid making major life decisions, such as spending large sums of money, buying a new home, or filing for divorce, for at least a year. This is a highly stressful time, and you need space to clear your mind and make wise choices. Instead, focus on self-care, including practices like meditation and counseling, to regain clarity. If your marriage can be saved, dedicating your energy to healing and rebuilding the relationship—rather than seeking revenge—will lead to healthier emotional outcomes for everyone involved.

5. Don’t try to handle marriage repair on your own or sweep the issue under the rug. Cheating is a clear indication that something is wrong in the marriage. Denying or minimizing the affair—by saying things like “all men/women cheat”—is simply a way to avoid confronting the issue. Betrayal erodes trust and intimacy on all levels, and the only way to heal is by addressing the damage with the help of a mental health professional. Numbing yourself or trying to forget about it won’t make forgiveness easier. Healing requires open communication, where your partner listens to your hurt, apologizes sincerely, and both of you commit to reshaping boundaries and rebuilding trust.

Betrayal affects both partners. One loses credibility and respect, while the other loses trust and faith. These qualities can be restored if both partners are willing to forgive and work together to rebuild what was lost. It won’t be easy, but if you can love your marriage more than you hate the betrayal, you can survive and even thrive in the aftermath of an affair.
