I can't get him out of my head.....?

I really, really like this guy and I see him once a week for like a couple if hours. I like him more then anyone else I have ever liked. He stares at me and I always feel so great around him. He is also really cute. But we don't talk that much. I want to know how to tell him I like him without actually telling him. But I just want to Be his girlfriend. And I just really wnat to be wiht him. How can I get him to ask me out and how do I let him know I like him????
