It starts with a heavy, cold pit in your stomach. You wake up, the sunlight hits the floor, and for a split second, everything is normal. Then the memory rushes back. "I cheated on my bf." It’s a sentence that feels like a physical weight. Most people think infidelity is always about a lack of love or a calculated betrayal, but the psychology behind why we stray is often way more messy and confusing than a simple "bad person" narrative.
Cheating is surprisingly common, yet it’s one of the most isolating experiences a person can go through. According to data from the General Social Survey (GSS), about 20% of men and 13% of women report having sex with someone other than their spouse while married. In dating relationships, those numbers often trend even higher.
But statistics don't help when you're staring at your phone, wondering if you should confess or bury the secret forever. You're stuck.
Why Did This Happen? Understanding the "Why"
Honestly, it’s rarely just about the sex. Experts like Esther Perel, a renowned psychotherapist and author of The State of Affairs, argue that cheating is often an expression of longing and loss rather than a direct attack on a partner. Sometimes, you aren't looking for another person; you're looking for a different version of yourself.
Maybe you felt invisible. Or maybe the relationship became a series of chores and "what's for dinner?" texts. When someone new looks at you with genuine interest, it’s like a shot of dopamine to a starving brain. This is often referred to as New Relationship Energy (NRE). It's a literal chemical high.
- Self-Sabotage: Sometimes, we blow up a good thing because we don't feel we deserve it.
- The "Exit Strategy": Subconsciously, some people cheat to force a breakup they're too afraid to initiate.
- Insecurity: A need for external validation to prove you’ve "still got it."
It's complicated. You can love someone deeply and still make a choice that destroys their trust. That paradox is what makes the "I cheated on my bf" realization so haunting.
The Immediate Aftermath: To Tell or Not to Tell?
This is the crossroads. You’re likely spiraling, asking yourself if honesty is always the best policy.
There is a school of thought—often supported by clinical psychologists like Dr. Janis Abrahms Spring—that healing can only happen through radical honesty. If you keep it a secret, you create a "silent wall" between you and your boyfriend. You aren't really with him anymore; you're with a version of him that doesn't know the truth.

However, some people argue that if it was a one-time mistake that will never happen again, "burdening" the partner with the truth is just a way for the cheater to offload their guilt. But let’s be real: secrets have a way of leaking out. A Venmo receipt, a stray DM, or a mutual friend—the truth usually finds a crack.
If you decide to confess:
Do it in a private, quiet space. Don't do it over text. Don't do it when you're both drunk. Be prepared for a reaction that might include screaming, silence, or immediate packing of bags. You've handed them a grenade; you can't be surprised when it goes off.
If you're considering staying quiet:
Ask yourself: Am I staying quiet to protect him, or to protect myself from the consequences? If it's the latter, the relationship is likely already dying from the inside out.
Can a Relationship Survive "I Cheated on My Bf"?
Yes. But it’s going to be brutal.
Recovery from infidelity isn't a linear path. It’s more like a series of setbacks. According to The Gottman Institute, which has studied thousands of couples, the "Atone, Attune, Attach" phase is vital.
- Atonement: The person who cheated has to take full responsibility. No "I cheated because you were mean to me." No "It only happened because I was drunk." Just ownership.
- Attunement: You have to stay in the room while they express their pain. You have to answer the same questions 100 times without getting annoyed.
- Attachment: Rebuilding a new relationship from the ashes of the old one.
It takes an average of two years for a couple to feel "normal" again after a major betrayal. That is a lot of Tuesdays spent crying over a phone that didn't ring. If you aren't ready for that level of emotional labor, it might be kinder to walk away now.
The Cognitive Dissonance of Being "The Cheater"
You probably don't recognize yourself right now. You thought you were a "good person." Good people don't do this, right?

This is cognitive dissonance. It’s the mental discomfort of holding two conflicting beliefs. You believe you are loyal, but your actions were disloyal. To cope, your brain might try to justify it. "He hasn't been romantic in months," or "It didn't really mean anything."
Stop.
The first step to moving past this—whether the relationship survives or not—is accepting the duality of your actions. You are a person who did a bad thing. That doesn't mean you are a bad person forever, but it does mean you have work to do on your integrity.
Assessing the Damage: Is it Worth Saving?
Not every relationship should be saved.
Sometimes the cheating is a symptom of a fundamental incompatibility. If you've been unhappy for years and this was your "out," then trying to fix the relationship is like trying to put a band-aid on a broken limb.
Ask yourself these hard questions:
- Do I actually want to be with him, or am I just afraid of being alone?
- Am I sorry I did it, or am I just sorry I feel guilty?
- Can I realistically give up the "extracurricular" attention for good?
If you find yourself wanting to keep tabs on the person you cheated with, you aren't ready to fix your relationship. Period.

Practical Next Steps for Moving Forward
The "I cheated on my bf" phase of your life doesn't have to define your entire future, but it will define your next six months. Here is how to handle it with as much integrity as possible.
1. Cut All Contact with the Third Party
There is no "we're just going to be friends." None. If you want your relationship to stand even a 1% chance, the other person must be deleted, blocked, and erased. This includes social media lurking. You cannot heal in the same environment that made you sick.
2. Seek Individual Therapy
You need to figure out the "why" before you can fix the "us." A therapist can help you dig into your attachment style or any underlying issues like self-esteem or impulse control. Don't rely on your boyfriend to be your therapist right now; he’s the injured party.
3. Radical Transparency
If you stay together, your right to privacy is going to be limited for a while. This means "open phone" policies, sharing your location, and checking in more often. It feels invasive, but it’s the only way to rebuild the "Trust Bank" you just emptied.
4. Give Him Time
He might want to know every detail. He might want to know nothing. He might want to break up today and get back together tomorrow. Let him lead the pace of the emotional recovery. You lost the right to dictate the timeline when you broke the contract of the relationship.
5. Accept the New Normal
Even if you survive this, the relationship will be different. It might even be stronger in some ways—many couples report that the "post-cheat" honesty led to deeper conversations than they ever had before. But the innocence is gone. You have to be okay with a relationship that has a scar on it.
Infidelity is a trauma. For the person who was cheated on, it can trigger Post-Infidelity Stress Disorder (PISD), which mimics many symptoms of PTSD, including flashbacks and hyper-vigilance. Understanding the weight of what has happened is the only way to move through it. Whether you stay together or part ways, the goal now is growth and ensuring that this version of you is the last one to ever make this mistake.
Focus on your own accountability. Look at your triggers. Re-evaluate what you want out of a partnership. Real change doesn't come from guilt; it comes from a conscious decision to be a person who is worthy of trust. That process starts with the very next choice you make.
