if the girl he is with is being nasty or treating him badly for no reason that's acceptable, or if she is talking about an ex or another guy she thinks is cute just to get back at her boyfriend.
be upfront and just tell him but to avoid conflict with his girlfriend do it in private
tell your girlfriend and then go to your boyfriend and say all the good things about your girlfriend
Yes.
then the guy will tell the girl yes he has heard of another guy...
it means that the guy or girl is with another guy or girl at the same time that they are with you
Become friends with him and then try to flirt without giving it away. If he notices what you are doing and tells you he has a girlfriend then you can't. If he doesn't tell you he has a girlfriend or if he asked you out he likes you.
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.
She looks more at the guy than you. Check her phone.
Tell him about it or tell his new girlfriend or you can make him jeoulous
he secretly goes out with the other guys girl
you ask her if she likes the guy if so - break up time if not - froget about the guy
He pays more attention to you than his girlfriend and try's to impress you
