I don't know what i did wrong

for the first month of school this guy I really like was always around me and talking to me and touching me and stuff and all the sudden yesterday he stopped talking to me..he doesnt even sit at my table at lunch anymore. we were fine hanging out on...

friday...I don't know what I did...and I'm almost positive he liked me before..he admitted to it and his best friend told me he liked me. AND HE ASKED ME OUT. I really don't understand what I could have done to make him totally cut me off. he barely looks at me. :/
I asked his best friend what was up with him and he was like...I don't know why chris does the things he does half the time

It sounds like he's a flaky kind of guy.
You probley did nothing at all, his friends even said that just the way he is. Maybe he just looses interest in girls really fast, or maybe he likes the chase for them, but then get's uninterested when he get's them ya know.

It sounds like he is unsure of his feelings and just has a habit of falling for girls then not liking them anymore - this is a common problem.

well what did you say when he asked you out and what I have seen a lot of girls like hard girls to get maybe you were too easy and wanted to move on and this guy isn;t worth it theres better guys out there girll :]]
