Would he still like me if...? Please answer?

[Gia]

I like this guy very, very much. He's in one of my classes in High School and he's younger than me, BUT more mature (Yes, he's the most mature guy in the grade). He's respectful, nice, very smart, social, approachable, etc.
He's also quite popular because he attends a lot of parties (even though he controls himself in them) and pretty much everyone likes him. I'm one of those shy and quiet type of girls that will only hang out with her group of friends. He's been showing interest in me lately, and we've talked over Facebook. We have really fun conversations because he always keeps them going, which motivates me into keeping them going also. I have liked him for about a month or so because he's all that I mentioned and also very attractive! He's NOT a typical guy, guys like him are really rare, especially if they're good looking also.
Anyway, do you think he can like me, even though I'm not the party type or the very social type? Although I can be if he gets to know me better.
Please help?!
Sorry, I forgot to mention we do speak in person too haha Mostly on Facebook even though I want to get to know him better
