How do I make a guy like me... a lot. And how can I tell if he does already?

Alright, there's this guy that I like and we dated last year, but it wasn't right. It was mostly his friends who pressured us into it, I didn't really like him then. But now I do... a lot. We're close friends now, but I want him to be with me for real. I REALLY like him. He's perfect. But I don't know how to get him to like me, he might already, but I'm not sure. Please help!
