So does this girl like me or what?

Okay, this might be long, sorry. Well there's this guy that makes fun of me and calls me a , but he doesn't know im really biual. So he started that whole rumor about me in PE. then this girl walks up to me and is like "woah, is what he said true" i just laughed and walked away, and told her not to believe him. which is stupid but all the guys in my cl would kill me, dang s. well anyway. that girl walks up to me in the locker room and is all, wow you're really skinny!! but it was odd.. because the only way she could have seen me changing is if she was actually like checking me out.. my locker was kind of blocking me, because i left the door open. haha. but then yesterday i walk out to pe, we ran the mile, and im sitting in the bleachers, she leaves all of her friends and comes to sit by me and my friends.. but she sat like really close and if i moved like even the slightest she would look back at me righ in my eyes and give me this really weird smile... is there a possibility she likes me or whats up?
