How to get my crush to love me back?

[Pink Glasses]

Hey guys so I've had a crush for the past 2 years and he doesn't like me back. I think about him all the time and how perfect we would be together. Many of my friends say that we would. He showed interest in my at the beginning of freshman year but then stopped talking to me because I sat next to my friend during class and we were really loud and always laughing. I guess that really annoyed him because he stopped talking to me. Anyways, how do I get him to feel differently about me again? I don't have any classes with him this year so theres no way I can talk to him and ask about homework or anything. He unfollowed me on twitter so I unfollowed back. What can I do?
