Is it normal that i think a straight guy might like me as more than friends?

I got to college in this program with very few people (around 50), so it's natural that everyone is friendly with everyone, since we're mostly always together and we'll have to spend 3 years together anyway, so we don't want to start some shit.

I consider myself pretty bitchy and moody. I have this group of friends that I am closer to that are referred as "bitches", and we don't necessarily want to talk to other people in the program. However, there's this guy that's overly friendly that kept talking to me, even when I let him know that I wasn't really looking to become his friend. Eventually, I gave in, and now we're friends.

I know the guy is straight, and I'm more than certain he knows I'm gay (it's pretty obvious), but for some reason he's always overly pushy in his friendliness. So much so that my friends and I think he might like me as more than a friend...

He keeps telling me I'm cute (apparently I look like a kitten), he always comes to me for meaningless conversations, he laughs at everything I say (even if it's not even remotely funny), and recently he invited me over at his chalet for the holiday vacations... I'm really confused, since I don't usually get that kind of attention from guys, and I know for a fact that he's straight...
