How to Deal With Infidelity in a Marriage

By: Katie Lersch: If you’ve found this article, I have to assume that you either strongly suspect or already know that your spouse has had an affair. If that’s true, I’m so sorry. I know exactly how devastating this feels – because I’ve been there too.

You’re likely feeling a confusing storm of emotions right now – shock, disbelief, heartbreak, anger, maybe even self-blame. You may be asking yourself, How could this have happened? or How did I not see it? Or maybe you’re simply numb. Please know this: everything you’re feeling right now is completely normal. There is no “right” way to respond to something that shakes your entire world.

In those first few days or weeks after discovering an affair, time can feel strange. You might feel like everything is moving in slow motion – or like life is passing in a blur. You’re trying to make sense of something that doesn’t make sense. My goal in this article is to offer you some direction, comfort, and clarity as you begin to work through the pain and decide what comes next.

Don’t Blame Yourself Or Beat Yourself Up (Even If You’re Tempted To): Before my own husband’s affair, I remember thinking I’d never blame myself if something like that ever happened. But when it actually did, that’s exactly what I did. Once the shock wore off, the self-doubt crept in. I began asking questions like:

“Was I not enough? Not attractive enough? Not exciting enough? Not attentive enough?”

Looking back now, I can see that I was trying to find control in a situation that felt completely uncontrollable. Blaming myself gave me something to do, even if it made no sense. I thought that if I could just figure out what I did “wrong,” I could fix it.

A close friend of mine reacted differently. When she discovered her husband’s affair, she overcompensated. She wanted to save her marriage so badly that she blamed herself entirely, made sweeping changes overnight, and tried to “win him back.” For a short while, the crisis actually created a spark between them — but underneath, she was filled with shame and resentment. She felt like she had betrayed herself just to hold onto him.

I share both of these stories because they illustrate something important: neither response actually helps you heal. Both come from pain, fear, and confusion — not from strength or clarity.

No matter what you did or didn’t do in your marriage, you did not cause your spouse’s affair. Your spouse made that choice. There are countless people who face marital struggles but choose honesty, counseling, or communication instead of betrayal. The responsibility lies with the one who stepped outside the marriage — not with the one who was blindsided by it.

When You’re Ready, Try To Understand Why It Happened – And What You Want Now: I want to be very clear here: understanding why your spouse cheated does not mean excusing it. But once the immediate pain and anger begin to subside – and that takes time – you may reach a point where you want to understand what really went wrong.

Sometimes affairs stem from a midlife crisis, personal insecurity, or unresolved stress. Other times, there are patterns in the marriage (like poor communication or emotional distance) that created an environment where disconnection took root. This doesn’t mean you’re to blame — it simply means that if you choose to rebuild, you’ll need to address these deeper issues together.

When you’re ready to have this conversation, try to listen for truth rather than defense. Your spouse may make excuses or try to minimize. Or, they may open up honestly about what they were feeling. You don’t have to decide what to do right away. Just take it in. Reflect.

When I finally listened to my own husband – really listened – I discovered that while some of what he said felt like rationalization, parts of it also revealed weaknesses in how we communicated. I didn’t forgive him immediately, but I did begin to understand the why. And that understanding later helped us rebuild something stronger.

Take your time to decide what you truly want. Maybe you still love your spouse and want to save your marriage. Or maybe you feel that the trust is too broken. Both paths are valid. The important thing is to make your decision from a place of calm reflection – not panic or pressure.

Define Your “Best-Case” Healing Scenario: After the dust begins to settle, ask yourself what “healing” would look like for you.
For some, it means walking away, closing the chapter, and building a new life. For others, it means fighting for the marriage and rebuilding trust.

Whatever your best-case scenario looks like, hold onto it. Let it guide your choices.

If, for example, your deepest goal is to eventually restore your marriage, then continuing to punish your spouse months later or obsessing endlessly over the affair will only slow that progress. On the other hand, if your goal is personal peace, then letting go of resentment will be part of that path — even if forgiveness takes a long time.

You deserve to move toward whatever brings you peace and wholeness again — not just survival.

Don’t Hesitate To Get Help (Emotional Healing Takes Work): Infidelity is one of the hardest emotional blows a person can experience. It shatters trust, self-esteem, and your sense of stability. You don’t have to navigate it alone.

In my own journey, I reached a point where I just couldn’t get past the cycle of forgiveness and anger. One moment, I wanted to rebuild, and the next I couldn’t stand to look at him. That constant back-and-forth exhausted me. Eventually, I sought outside help – and that made all the difference.

Sometimes, talking to a trusted friend helps. Other times, professional counseling is necessary. Either way, seeking support isn’t a weakness. It’s wisdom. It helps you process the pain in a safe, constructive way rather than letting it consume you.

And don’t forget self-care. When your confidence has been shattered, nurturing yourself isn’t optional. It’s vital. See friends, do the things that comfort you, and remind yourself that you still matter, deeply.

Moving Forward: What I Learned: There’s no easy way through infidelity. It changes you. It changes your marriage. But it doesn’t have to destroy you.

In my case, it took time – and a lot of work – but my marriage eventually healed. More importantly, I healed. I came out stronger, wiser, and far more self-aware. I no longer live in fear that my husband will cheat again, and I know now that I have the tools and resilience to survive anything.
