Help me and i will love you?

lol, well not really. I HAVE A MAJOR GUY PROBLEM. Here's the thing, there's this guy in my math, zack, and he has been in the cl for half a semester with me and we've never talked. EVER. His friend, austin, is also in that cl and i sometimes talk to him. i''ve been crushing on zack forever and i've been wanting to talk to him, but he and austin sit all the way across the room and i can't just get up and say something, it would be incredibly akward, especially since austin would be all like "um why are you here?" :[ I have no idea what to do, i can't talk to austin to get to him, and i never see him anywhere else. Sometimes ill catch his eye from across the room and he'll instantly look away. and one time austin called me over for help with math, and zack wouldn't even look at me :[ he totally looked the other way. HELP ME. he seems like such a nice person and i want to get to know him. plus sadies is in two weeks!! :[
