You shouldn't have done anything with him knowing he has a girlfriend.
No it is wrong to do so. A guy should help instead considering the condition of the lady.
narrow your question down!! possibly if a girl cheats on him or if she doesnt turn up to a date etc
Well, in Brazilian Portuguese, 'corno' is the way you call a guy whose girlfriend has cheated on him...
Did you not know he had a girlfriend? If he was hiding it from you... i'd say slap him/kick him in the balls and let his girlfriend know what he did.
A guy who has been cheated on before and is scared that you'll do the same. just keep re-assuring him that you wont. It's not easy overcoming finding your girlfriend cheated on you.
obviously she cheated on you dude its obvious if shes gone for awhile and says she with friends or somethn she is banging another guy
hurt him with the one thing he cares the most. find a way like if he has a girlfriend tell her what happen then ask her if she would cheat on him
No, because of the fact that he cheated in the first place
Dump her, if shes cheating on you shes not worth it. Once a cheater always a cheater. My ex girlfriend cheated on me with a guy and i forgave her and after we broke up, i found out from her friends she cheated on me with 6guys including my best friend.
That you are either a saint or an idiot if you stick around. Sorry to be so blunt, but REALLY!
If you really care about your girlfriend, you tell her that you cheated on her and that you are really sorry you did. You promise you'll never do it again. (and don't do it again). If you're lucky, she'll forgive you.
