you can tell him, or his girlfriend if you are friends with her
Depends if you are friends or not. If not friends then tell her to leave you alone.
it means he want to show off to his friends he has a girlfriend
tell his girlfriend and all your Friends so everybody can know how much of a jerk he is
if there your real friends then they would be supportive of your relationship, and you shouldn't let your friends make fun of you girlfriend. remind them who has the girlfriend around here, And maybe they should get a girlfriend. But if you tell them to stop and they won't then forget them.
tell your friend that you like he and if your friends with the (girlfriend) tell her that you like him and if she gets mad DRAMA QUEEN then when they break up you have a chance. :):):)
just tell her you dont feel the sparks anymore/ever
Tell her to tell him the truth and discuss with him what it means to be friends.
Try to trick him or get wasted is what i do
Tell her that you want to be just friends. Communication is key!
.............you can tell if your girlfriend is envolved with her best friend because she will be extra emotional around her. She will touch her alot and talk about her all the time.
Yes you should tell her that he is cheating. Because later, it will hurt her if not told.
