I really like this girl at school, we get on so well together but she has a boyfriend! Hes left school so we spend loads of time together at school, and she texts me out of school but I don't see her often. At school I don't know if she's flirting or she's just really friendly, she touches my arm and my leg sometimes when we are sitting together, and just the other day we were sitting alone in a room watching TV she was sitting to me left facing across me and she put her legs across mine. She hugs me a lot, and rests her head on my shoulder or cuddles into me saying she's tired! I always catch her glancing at me but don't know what to make of it all, can anybody tell me what they think and what I can do??
