Do you think this girl likes me or is just being friendly?

[gregory]

So there is this girl who was in my theater class last semester and in my math class this semester. Here are the things that I think show she might or might not like me in semi chronological order. So last semester she asked to be in my group for a play project thing, and the play we picked was kinda sexual. She talks with me and my group of friends in my classes with her. We had this one conversation about like dating and flirting which is what made me think about whether she liked me initially. She invited me and my friends to her 16th birthday party, and encouraged me and my friends to stick around a few times. It seems like she is smiling a lot when she is talking around me and she seems to kinda face me when I say something or she talks to me(I think), she laughs a lot as well in a nervous kinda high pitched way. One time she asked me to do up her scarf, which involved touching her hair. Also I feel like she kinda of acts a bit like sexy around me. I have messaged her on facebook a few times and she seems to respond well to it. However she doesn't always talk to me in conversations but she always responds if I say something, and it is possible she might like my friend instead, he is present for a lot of this as well. I know this is long but I want some opinions before I decide whether to do anything.

I think she really wants to be your friend/best friend because she's trying to be open o.o if you know what I mean o.o she's inviting you to groups and having conversations with you
you should ask her if she likes you like more than a friend or not?
