ask people that know him, like his friends or a family member. They'll probably know if he does.
You simply ask him.
When he calls you his girlfriend.
Spy on him! A wife caught a guy redhanded giving nude photos of himself to his girlfriend.
If he likes you, then he won't have the other girlfriend anymore.
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.
tell his girlfriend and all your Friends so everybody can know how much of a jerk he is
Yes! The guy i like has a girlfriend and we are good friends and i don't know who his girlfriend is but he said that he liked me. So there is hope!!
Im a guy and I think I think I would want to know when another guy hits on my girlfriend
If you dont know who the guy is then you should find out before being jealous. But if you do know the guy then you should just go have a long talk with your girlfriend because if you are jealous, your girlfriend might just break up with you.
The only way to know for sure is to ask her.
No one right he's 29 and no girlfriend I feel sorry for the guy. Il like to be his girlfriend too bad I don't know Korean.
Meet with the guy somewhere secret? I don't know.
