PLEASE help me - its about a guy I've liked for two years -- (Lots of answers, please.)?

I don't even know him! His favorite color, his moms name, what he wants to be when he graduates from college ; none of that. But I know he's sweet. 8th grade, he was best friends with my best friend, since they were in 3rd grade. I went on her bus and stuff, and he used to say nice things about me how I'm pretty, and the nicest girl hes ever met and he seems like perfect for me. You know how some guys are all macho, and show off and say stupid things during cl to impress people? And there are some girls who do that too, I'm not like that and neither is he. He just seems absolutly perfect for me. So, I've been "crushing" on him since October during 8th grade. And, since my friend went to a different school, it was sortof our bind to talk to eachother, Like, he was my lab partner in science, we had art together too. (8TH) And 9th grade, we had english together. And he was so nice and sweet to me in the beginning of the year, and then I started really liking him again so I was more nervous around him, and started not talking to him as much, and I felt like I was annoying him (probably not but i'm just gay like that) and so we only talked alittle for the rest of the year, and now its seven days before 10th grade starts and I still think of him. He's the face I see when I lay my head on my pillow, and close my eyes. I think about him, and if he's thinking of me, and stupid girly stuff like that, and I even get erflies when I see him. For ex) I was on Facebook, and one of the girls in my math cl just got a facebook, and so I clicked on her pictures because she told me there was a funny one of her in a tree, lol, and on the screen there was a picture of him and her (they're friends from 3rd grade too, no worries) and my heart skipped a beat - literally. Can crushes be this intense? Can you be in love without the other person, and without even knowing them? And, how can I get over him. Almost TWO YEARS I've just been in a daze with him; like when a few guys asked me out, I said I had a boyfriend, because I feel like it wouldn't be fair that I feel like this about him, and they like me. How can I get over him? I know I already posted this but I only got two sucky answers. Thoughts of him are taking over my life!
