Is cheating acceptable?

Let's get past this then, shall we? What if someone is only emotionally attached to another and has no real physical attachment? Does that constitute cheating? I have my own answer due to personal experience, but I'd be curios what others think.

@vezax: I guess he has well healthed brain and knew the answere from the beginning. This thread is like: "Uhhhhh it is not ok to cheat, I guess you know that too, but I post it anyways to show that I clearly don't support cheaters nor cheating in general."

@Wasistdas I wanted to know how many people felt the same way. I was curious if this was a common ideal. At the time of posting there was a different community here willing to explore this honestly and add to the conversation. To the people who want to change the topic completely make your own damn thread and stop complaining here. I promise there isn't a thread limit and it won't hurt you to be constructive here.

yeah infact not all are against the concept of their gf cheating on them, i mean few people have this fetish of their gf cheating on them... its called cuckold/netorare.

Some people probably will hate me after what I'm going to tell. I cheated, to my ex eyes I cheated. First I wanna say something. I am bi poly, he was straight mono. Like intelligent people, we talked about it, and we decided something that would make both of us happy. Our agreement was that, if I ever had the change to do sex with a girl, I could do it once. I was curious about something he wouldn't be able to give me, and he preferred to know that I did it once, instead of cheating him more than once. He didn't considered cheating if it would help me understand more about myself and my tastes. This is a big example how a poly and a mono people can work. About the cheating part. After one year dating, I asked for a break, cuz I didn't felt really in love with him. After 2 weeks, I decided to talk to him, just to talk. 1 hour and he was already "my sweetheart" "let's play dear~" "You are so pretty ^^". I didn't said a thing, I didn't liked someone else at the the time, so I though that maybe I could learn to love him again. Some months passed, one more break, another break, I liked him, but not as much as he liked me. I said I wanted to break up, but he insisted that I should try a little more. I did. Some weeks, one more wish to break up, one more try. I started liking a classmate. My ex was a nice guy, but not the one, I didn't wanted to tell him that I had feeling for someone else. He moved from his city to a close one so that he could life closer to me. Things started getting weird. He would sacrifice for me, literally. So, I started having some kind of relationship with that classmate, at the same time I was trying to break up with my ex, without hurting his feelings. In the end, I ended up telling him that I was with other person (even though me and my classmate weren't officially dating). I cheated, but is he the bad person? He didn't allow me to end up with him, but am I the bad person?

Sounds like you both handled it badly. He should have taken the hint and broken it off, and you should have been firmer about breaking it off - that's a long time to be having and on-off relationship. Should have stayed broken up after the third time at most - clearly it wasn't working.
