Get over him. If he was interested in you then you'd be dating him right now.
If you refuse to listen to the voice of obvious reason and want to confess your love only to be either toyed with or rejected then by all means feel free. Here's how you do it: call him up, ask him to meet up with you, tell him you have something you want to say, then pop the three big words ending with the L word. After that you'll probably be rejected. It'll hurt then you'll be mad, you'll blame him even though he's doing NOTHING to indicate that he wants you, then you'll get over it and move on.
Also, get over the whole "the way he looks at me thing". He's looking over at you because you or your friends are doing something to get his attention. Everyone thinks their crush looks at them differently than everyone else. And they're actually not.
