Does she like me...? Please tell me!!! I need to know!?

Wow, that was a long question. I know you are afraid of rejection, but there really isn't anyway to know if she likes you unless you take a chance. It sounds like you are already friends with her, and are pretty comfortable around each other. Go for it and ask her out, it i a risk but sometimes in life you have to take risks. You might also want to try and just be really honest with her, and tell her how much you like her. A lot of girls really admire when guys are honest with them like that. Go for it, take a chance. She can never say yes if you never ask her. Good luck!
