It’s many people’s worst nightmare. You happen to glance at your partner’s phone and see a flirty message from a name you don’t recognize, or you notice they’ve been “working late” a few too many times recently. Betraying a partner's trust by cheating is one of the quickest ways to destroy a relationship, yet somehow, nearly a quarter of men admit to having been unfaithful.
To get to the bottom of why people commit infidelity, one curious Reddit user asked men who have cheated to share their reasoning. Hundreds of men weighed in with brutally honest answers, so below, you can find some insight into what makes a cheater, as well as conversations with the person who started this conversation and Licensed Marriage and Family Therapist Shane Birkel.

Because I forgot what a healthy relationship was like.
After 3 years together, my then gf and I kinda ended up in a rut, in hindsight we stayed together longer than we should have. We were living together but had already grown apart too much.
She eventually told me, pretty much in passing, "Hey, btw, just a heads up, *male best friend from college* has expressed that he has feelings for me, but idk if that's mutual or not yet, so I'll keep you posted I guess".
That level of disloyalty and blatant disrespect straight to the face broke something in me. She had managed to shatter every last ounce of self respect I had left after months of dealing with her b******t. Deep down I knew the end was coming and started to pull away.
I went out drinking one night while visiting my parents with some of my high school friends and met a girl I knew vaguely from highschool as well. I didn't even mean for it to happen, I had brushed of every advance whatsoever since I got serious with my girlfriend, like I should've, but after her comment about her friend I just didn't have the energy anymore.
And man, I had just forgotten what that was like. To have someone actually be excited to see you. To not feel talked down to. To have someone be genuinely interested in what you're up to and what you have to say. To not have every conversation you have end in a rant about what you're doing wrong and how you're useless. To have any form of intimacy that doesn't feel like a chore that's just for her benefit.
I'm not proud of what I did, but I won't regret it for a second either. I know for a fact, with 100% positive, willing to bet my house and life savings levels of certainty, my ex gf would've done the exact same, and more, had she been in the same situation.
It felt like a wake up call. We broke up the next day and I honestly felt like I'd been freed. I ended up dating the girl I met that night for 6 months.
I don't condone cheating, ever. I'm not proud of what I did. I've reflected on that time extensively, both by myself and in therapy, and honestly, I did everything I could. I know I wasn't perfect, but she wasn't either, and I know for f*****g sure I tried everything I could to make that relationship work out, and it didn't. I'm not proud of what I did, but I sure as hell don't regret it either.

I was 18 and kissed another girl while drunk. I felt terrible and made my girlfriend (long distance) feel really s****y but she also understood it was more of a lapse than any sort of emotional or really even sexual violation. She was way too cool about it. I’d never want to do it again.

She was withholding sex whenever I said something slightly wrong in her eyes. She would do this for months at a time because one time she asked if she should lose weight and I said « you should do what you feel is best

Alcohol mixed with being wanted by someone beautiful. I know it’s not a good excuse and sure I’m an a*s, but you wanted an honest answer and I’m sure I’m not the only one

At the time, I thought I was doing the right thing. Hear me out: my wife had an anxiety disorder which made sex painful. I thought I would get that need met somewhere else to take the pressure off her. I thought I loved her (I did according to what I thought love was at the time) so I didn't want her to be upset for not meeting my "needs". I justified it to myself that way for awhile. I learned in the end that we were just unhappy together. Pro tip: don't get married young or thinking it will solve any problems. We were divorced just under 5 years later. She is remarried and has been for many years. I have had one relationship that lasted 2 months, 12 years ago. I never want to hurt anyone like that ever again, so much so that I've avoided relationships.

Wanted to try something new. Needless to say, the relationship went bust thereafter.

Honestly, it was the chance of a lifetime. She is the perfect girl, I had loved and chased her on and off since high school, we had been vague acquaintances at best, I doubted she knew my name. One day she messages me out of the blue if I was still living in the city I was living in, that she had some business and that we could meet up. We meet and have an amazing time, there's some alcohol. She comes back to my house and says she's had a crush on me since high school as well, we decide to play a drinking game which becomes a taking of clothes game. I'm laying on my bed drunk in my underwear, she's standing beside the bed naked and says "now what", and then I just couldn't contain myself anymore. I have absolutely zero regrets.
