If you both like each other and both of you know y'all like each other. The best you can do is go and ask her out and see what happens from there.
get a friend to ask but it should be someone that talks to both you and the girl
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?
only if you like her back
If she likes you back, then you should definitely go for it. Ask her out to a movie, or to supper or something? Or you could even ask her to be your gf. If she likes you back it should be no problem and you have no reason to be nervous or confused as to what to do.
Ask her out!
Yes. If you like her and she likes you, you should deffinately date.
Forget about her till she is alone again
If when you say hi she giggles or smiles or both
you have to tell her its only good to do and this is from a girl.good to help.
Move on and find someone else.
you and that girl should explain to her bf. that they both like each other. then you and the girl should try to figure out who to date.
Maybe you should wait a little and see if she likes you if she likes you ask her out.
