Is she legitimate or not?

There is a girl in my class who i used to kind of chat with. It was normally with a group of people anyways but shed always say things like, "I love brent, hes soo nice!!" in front of me, to her friend, but she is looking at me. I didnt know if she liked me or not but i wasnt bothered by it. Then one day, I say "Hi alex!" and she would say, "Hi!" kind of awkwardly and then would like flick her hair at me and talk to her friends. Its the second time shes done it and it really bugs me. She calls me nice and stuff, and cool but then im the only guy in our class who doesnt have her number. Like wtf? It wasnt like this in my other school. I thibk shes a bytch and i am going to ignore her. But was she into me or not?
