if he starts rubbing your hips
Talk to him. And work something out.
then he must be cheating on you if he has a girlfriend? i mean if he likes you and has a gf then he must be cheating and wanting you?
get to know him more to work out in what way you like him.
when he says he likes you.
iam in love with this guy but i do not know if he likes me or some other girl
If a guy likes you but you don't know him he may look at you or walk by you whenever possible.

It is ok to like a guy after you know he likes you. That is perfectly normal and a part of life.
You ask the guy.
don't
his eyes will open wider if he likes it
