give it a shot
Treat her better than her boyfriend does.
welltry and be friend with her and if you like her tell how you feel then if she breaks up with him there you go
If the girl has a boyfriend already,try not to get in the way. If she really does love you then she will break it off with her boyfriend. Don't try to rush her though as girls don't like that. Trust me, I am one.
Ask her on a date
wait until she breaks up with her boyfriend and then make your move
Patience. You shouldn't expect her to like you as a boyfriend if she already has one but you can still be a non boyfriend.
If he is her boyfriend, hopefully, she would like him.
act mysterious and give her a sign
try to brake them up :)
try to impress the girl if that doesn't work sorry shes gone
It may be hard to do, but always talk to her... if she doesn't like you or doesn't feel right about the situation leave her alone and find someone better:D
If u like a girl who already has a boyfriend but you dont know if she likes you or know,the first thing you have to do is that you will have to make friendship with that girl and if she is already your friend,then increase your friendship and one day confidently ask her that what does she feel about you..
