Is this girl biual?

Okay, lets say you have a friend of the same gender. They have said "you're y" a few times. Says "love you" with bunch of heart eyes smileys and then says "kissy" with a bunch of kissing smileys on AIM. Has said love you lots of times before to you. Playfully says "I hate you!" Once, she has said "I'm in bed", you say "same" and then she says "cool" with a kissing smiley on AIM. Talks a lot of good things about you to her other friends(ex. "she's cool", "really nice", etc). Her friend's friend's mom says she feels like she already knew you(have never met but tells you this when you do meet). And your friend's friend's lil sister says without meeting you yet, on AIM that your pretty, cool, funny, etc. Picks you out of all her friends including her besties to go somewhere. Likes to annoy you. IMs you everyday either as soon as you get on or around 10 minutes after. Is for gay marriage. Only thing is, talks about her guy crush to you all the time. Would you say she's bi and possibly has a crush on you?
