I Just Started Middle School Today And Already I Like A Guy!!!?

I started sixth grade today and I met this cute guy. He's in all my cles including homeroom! I have a huge crush on him! He doesn't even notice me though! I'm what some of you guys would call the top cheerleader, so I have all the boys on me. (not to sound conceited. I'm actually really nice!) But he's the only one who doesn't even look at me and I like him! What do I do? I'm not going to find a new crush. Usually, I don't even have crushes. I just tell my friends I like a guy. They tell the whole grade. And by the end of the day he asks me out, but now he doesn't even look at me!!!
