When the time is right and they broken up wait a few months later. Get to know her better, make her feel happy, and ask her out when the days feel just the right to do it. If she says no, she doesn't deserve you. If she says yes, go for it.
Treat her better than her boyfriend does.
You can't.
Tell you her your feelings about her
That's NOT Cool man.
just by being your self
just a friend
wait until she breaks up with her boyfriend and then make your move
It means she is about to dump her boyfriend and pursue you.
Bella Thorne already has a boyfriend so you cant be hers.
It might be hard to accept, but the girl already has a boyfriend and trying to get her to like you would not be the right thing to do. The only advice I can give you is to become friends, nothing more, with her. After all, she may not be with this boyfriend much longer and if you are already friends when the relationship ends with her boyfriend, you may have a better chance of being with her afterwards. After all, you'll be the person she can rely on or the "shoulder to cry on" as she deals with the pain of the break up.
give it a shot
