Be nice to her, look at her in the eyes. . .kiss her.
with lips. and tongue.
Tell him that it is very impolite. Make him understand that she is your girlfriend and he should stop undressing her with his eyes.
make sure that he is flirting with you...and if he really does like you then tell him that you cant go out with him until he breaks up with his girlfriend.
make the girlfriend look bad
If you like a guy and he has a girlfriend then you should back off and only try and be his friend.
I think you should make sure if he likes you and make sure he doesn't have a girlfriend. If he doesn't, ask him out or make it clear that you like him so he asks you out.
My girlfriend. Back away.
Yes
You shouldn't have done anything with him knowing he has a girlfriend.
If you are dating then by definition you are his 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.
A guy doesn't have to have a girlfriend. If you want to that's ok. Nobody should have to force you or say that you should have a girlfriend. It's YOUR choice.but if you want to have sex than you should have a girl friend.
