I know a girl in my school and I'm pretty sure likes to be around me. The problem is when we're alone or if she comes to see me, shes fine and flirty, even if its in class its just noone else pays attention to her, but if I see her or start flirting back she instantly distances herself, and instead acts openly flirty with another guy in the group. Today she came in while i was in the computer lab and talked to me and laughed at a couple of stupid jokes and even let a few "accidental" touches, but at lunch when we were with mutual friends I started the conversation and she didn't say anything, and ended up leaving. When i followed to ask whats up one of her friends put up a bitch sheild and i had to spend the rest of lunch killing it (successfully

) I'm just confused on what game she's playing, or if shes just trying to stay safe...
