looking down your shirt...
sounds kind of pervish to me.
and i don't know every boy is different. you can never tell if he likes you or if he's just flirtin
i agree with lauren.. he sounds pervish. but all guys are different, like she said.
i would stay stick with the flirting and just see what happens
but from what you have said, it sounds like him more wants to flirt. again though all guys are different
