She would stare at him and try to get close to him
You could tell him that it would be hard for u to d8 if he wuz dating her
It would be the best to tell him... It would be more worse when he sees his girlfriend doing something with another guy... You should handle the problem easy, and explain him it on an easy way. Ask him to talk with the girlfriend about it and handle it from there on.
1st tell him to stop and then it dosnt matter if you like his girlfriend or not tell her
The best explanation is really just to show off to his friends. He doesn't wanna seem like a loser to his friends so he says your his girlfriend
you can tell him, or his girlfriend if you are friends with her
You shouldn't have done anything with him knowing he has a girlfriend.
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
Go to the guy and tell him to tell his girlfriend that he has a crush on you and that he thinks they should get over each other.
You don't.
tell his girlfriend
Just get him into bed, that oughta do it.
