Crushes...help please?

There's this new guy in my school, I see him every day and we even share a cl. The first time I saw him I found myself very infatuated. Every time I p him in the halls, or see him in cl, my heart feels like it skips a beat. I know it can't be true love because I don't know him all that well, I really only know his name. I'm too shy to talk to him but I want to send out signals that I might be interested, but I'm afraid because I've been through a relationship that ended with my heart being broken, sounds really sappy, I know. And he probably wouldn't be interested anyway, or maybe he is, I don't know. Every time he looks up, I look down and pretend not to notice. Any advice on what to do?
