Men that cheat on their wives or girlfriends are often bored, don't like their significant other, or simply got drunk. It is not always their fault, but if you ever are in such a situation the proper thing to do is to not lie about it and be open. If it gets you dumped, so be it.
Most likely because the Girl hates the other Girl and just wants to make her jelous.
You shouldn't have done anything with him knowing he has a girlfriend.
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
if your girlfriend cheated,you should end the relationship
if she cheated or if she is a nagger or a shopaholic and you can't afford the expenses.
None of them have cheated.
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
how do you know if your boyfriend has cheated
No, because of the fact that he cheated in the first place
