Does the girl like me?

She laughs at all my faces, she graves my muscles a few times, she has invited me to go somewhere but I was buysy and she hasn't again. When I lean against a wall she lays on me, she sits on me and when I creak her out she dosent walk away. She teases me about being MLG quality in halo and for playing to much, and she is afraid to show me a bad side to her. Also another question. She asked me if I likes her with straight or curly hair and I said straight and she got sad. Why?
