Reaaally shy boyfriend help?

Ok so we've been goin out since friday and we hardly talk on the phone, we talked on the phone for 301 minutes, yea i know thats a long time but the majority of it was silent. I couldn't wait to see him at school after the weekend. Yea and hes REALLY REALLY quiet in person. And whenever i try to talk to him about feelings he just cleverly changes the subject. I don't know what to do I REALLY REALLY REALLY like him a lot.
