Title says it all really. 

not cheating but ive been involved in acts that are arguably just as bad. Ive ended up cucking several people resulting in their relationships ending, and have broken up with people for the sole purpose of dating somebody else. relationships are a slippery slope but at the end of the day, they were the ones who cheated and i left a bad relationship for a better one, so i dont really feel bad about any of it

nope, ass move.

1) Adultery isn't a crime in the US

2) Cheating on someone (assuming you aren't married) isn't the definition of adultery

3) ..its having sex out of marriage. So if you aren't married to the parter you are cheating on, you were also committing adultery with them as well.

Nope, it just makes no sense to me. I find it immensely disrespectful. If you have an issue with a relationship, just get out of it instead of cheating.

I have done so once. And I paid dearly for it years later. It was certainly among the biggest mistakes of my.life, and it ultimately led to the worst emotional pain in my life.

As to why..... I don't have a good answer. It was early in my relationship, and an ex that I knew to be great in bed made it clear to me that she wanted to fuck. So, I did it. I knew it was wrong, but I also didn't feel a particularly strong connection with my new GF at that point. At least, that's how I justified it.

The new GF essentially caught me a couple of days later. But, she didn't have any hard evidence, so I just denied it for long enough that she decided I must be telling the truth.

About 4 years later,that GF and I were days away from becoming engaged. That same ex called.me, as she did from time to time (I hadn't done anything with her since the incident mentioned above). I never answered her calls. On this particular night, I decided that I had to get her out of my life once and for all, as marriage was on the horizon. So, I decided to go talk to her at her place of work (a public place), try to nicely tell her that I'm marrying another woman, she can't keep calling me, encourage her to work things out with her husband, etc. I thought this may help her feel some closure, which would allow both of us to move on with our lives.

We talked for about an hour after she got off work, sitting in the front seats of my car. The talk was productive. We left with a hug, and what seemed to me to be satisfactory closure for her. On the drive home, I felt great. It finally felt to me like that chapter of my life had closed, and I was finally going to marry the woman I love. I started planning the exact proposal the next day. We had already come to an understanding that we were ready to get married to each other. I just needed to go through the motions with a ring, bended knee, etc.

A couple days later, the GF and I go to Target in my car. We pull up in the parking lot, she steps out if the car, looks down, and sees the ex's name tag from work sticking out from under the seat. That drive to Target was the last time we ever spent together

I was completely devastated. Frankly, though I've moved on with my life, married a great woman, and nearly a decade has passed, I still think about this monumental fuck up regularly. It had a truly massive impact on my life.

I did. With her best friend.

You see, let me tell you a story: It was a stormy night, my gf at the time (my ex now) and I were spending the weekend in her best friend’s fiance’s cabin up on the hills. It was just the 3 of us as her best friend’s fiance had been called back due to family matters. Always thought her friend was cool as we hung out a lot (even without my gf or her fiance) and liked a lot of the same things. Heck, I would easily say that we were much more alike than me and my gf was. Didn’t really have a lot of female friends at the time but I would say that she was one that could really hang with.

Anyway we were bored so the 3 of us decided to pass the time talking and laughing and drinking wine and playing cards. My gf played as the “bank”. Time passed. We’ve already had quite a bit to drink and things got a little heated. My gf had won almost every game and me and her best friend were down to almost our last chips and my gf, drunk as she was, loved to remind us how badly we were doing. I’m usually used to my gf being a little abrasive when drunk but this time she was downright obnoxious. Likely a tactic to make us do even worse at cards. I would often look to her best friend and nod apologetically and we would both share a smirk. It got to a point where my gf and I almost got into an argument as I was quite drunk myself and I wasn’t really all that able to take the sometimes rather mean jabs she was indiscriminately throwing our way. We were down to our last chips and were just ready to quit so we threw all our chips on the table and bet it all so we could get this game over with and do something else. We lost interest in the game long ago so her best friend and I were actually having our own conversation on the side talking about our shared interests in games and comics. Laughing and getting along so as to shake off my gf’s rude provocations. I’d say in that moment, we actually really clicked more than we usually did as we both had our shared annoyance at my gf. We went thru another bottle of wine.

My gf volunteered to open another bottle, groggily stood up and headed for the kitchen. We knew it would take her some time to get back as she could barely walk straight. At that moment, her friend and I looked at each other knowingly and just knew. We knew what we wanted to do. We didn’t even have to say it, but we did anyway. So I looked her in the eye, gestured for her to be quiet and finally said what we both were thinking: “Let’s switch cards out of the deck so we can finally win!”. So we did. We won that hand, said game over and much gloating commenced. And that is how I cheated on my gf with her best friend. That was many years ago. Til this day, she doesn’t know. And I’ve since lost contact with both of them. True story.

depends how you define cheating really.

I have never had an emotionally connect relationship with anyone but my wife. But I may or may not have stuck my dick in a few places.

I never did.

Yes, it is just part of life, just make sure to keep it purely carnal and protect yourself. I also thought similarly to many in this forum when I was in my late teens, but life and experience changes you and as you get older you realize that all these little things mean nothing after you die so there is no point in getting hung up on all that nonsense. Enjoy your life and whatever you do just make sure you wont regret doing it, or not doing it, later.
