You should tell him that you cannot be with a man who's with another girl and hurt someone else like that i mean get real.
Snuggle in with the cat and your girlfriend. :0)
Eff her
If your girlfriend is sleeping with you this should be considered a good thing. If not then you may want to make your feelings about not sleeping together be known to her.
If you like a guy and he has a girlfriend then you should back off and only try and be his friend.
My girlfriend. Back away.
Yes
If you are dating then by definition you are his girlfriend.
You shouldn't have done anything with him knowing he has a girlfriend.
If u want to be slapped
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.
tell his girlfriend
