My girlfriend. Back away.
if your girlfriend cheated,you should end the relationship
it's not that he "should" or he "shouldn't", if there is a boy who likes a girl and the girl likes him back, then why should they not be together?
Wait for him.
MAYBE YOU SHOULD IGNORE..
You should be as nice to the girlfriend as he is. If he's really into her respect it, but if he treats her poorly they should break up anyway.
If you want him enough to go into that circle, ask him how serious his relationship is.
well u shud actually tell the boy how u feel when he likes u back but make sure he ditches his girlfriend
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.
Don't meddel. If he likes you he will show it. If he has a girl, it is bad news to date him.
Yes you should and ask her why she wants to break up.
I don't know there should be a problem unless in a relationship already, I wouldn't recommend doing anything about it, just kind of ignore it. If the ex-girlfriend created some bad problems while in the relationship, I defiantly wouldn't recommend trying to get back together.
