She seems like she likes me but doesn't talk to me?

there's this girl who I've been catching looking at me, when I make eye contact she either holds it or looks away. She does it everywhere, in the hallyway, gym, lunch. She speaks unnaturally loud and does insane **** when I'm around. Also, I've noticed every time I walk in the room she immediately goes to her friends or the opposite, she'll detach from them and linger near me, and does the loud talking thing. She tries to get closer to me and bumps into me or gets into my way sometimes. We only had one real conversation where she started touching my hair, all of the others were her asking me questions or complimenting me. And the only reasons why this is weird is because, we've been, I guess you can say acquaintances for the entire school year and she just started doing this now. 2nd, she has a boyfriend! And lastly, she is very social, so if she was trying to get my attention to start a conversation, why doesn't she just talk to me?
