Try to get to know her better and see if your (or her) feelings change.
if a girl knows you like her, chances are she will flirt back. if she doesnt flirt back...move on, she isn't interested!
That she probably doesn't like you back.
Suck it up and don't annoy her.
She might not be interested in you. Just because she knows you like her doesn't mean she will like you back.
it means that she knows you like/are in love with her
Make a move since she knows.
ask her... its really the only way to know for sure!
Be honest. If she thinks you're weird for being who you are, fine. But you never knows if you like her back.
Yeah a boy can like a girl even if they aren't dating. I like a boy and we aren't dating... maybe she even likes you back. Who knows?
Its because his shy ! :D He wants to make a good impression on her, so that the girl will still like him !
Smile.
leave her alone and seem...mysterious. or just ignore her back!
