If she knows, it most likely will open up a new side of her (if she likes you that is) which she might want to talk to you more, become shy around you or laugh at almost everything you say even if its not funny. If she doesn't like you she could act more shy, try to avoid you or just annoy you more but mainly try to avoid you. P.S A girl answered this :)
it means that she knows you like/are in love with her
Make a move since she knows.
Smile.
if a girl knows you like her, chances are she will flirt back. if she doesnt flirt back...move on, she isn't interested!
Ask her out.

That she probably doesn't like you back.
sometimes ask her out and see what her reaction is
sounds like a player
No maybe who knows
I thnk that's a question only a girl knows the answer to.
She might not be interested in you. Just because she knows you like her doesn't mean she will like you back.
