Why would he suddenly start talking to me?

This guy is vain, conceited, and is a bit of a jack*ss when he's p*ssed off. He loves showing off and is good-looking and popular. When I first came in 3 months ago, he has never looked at me, talked to me, said hi, introduced himself, etc. but since 2 weeks ago I've been staying @ a student accommodation where his best mate also stays. Ever since the first night, we've been hanging out after school almost everyday playing PS3 and talking (brief conversations only though). A few days before and since that night he's been saying "hi, " and says my name A LOT when we talk/when he says hi. After spending time with him/hanging out with me I've developed feelings for him. After getting to know him, he's really nice and friendly after all (he's still vain though haha). Why would he suddenly talk to me and saying hi to me almost all the time, saying my name all the time, etc. when in the past he didn't even want to get to know me?

And he's the only guy who does this. I have other guys but they're just acquaintances in this school and they've added me on facebook.

Am I reading too much into this and is he talking to me cause he wants to be friendly and nice or does he actually have interest in me?
