Ok so I really like this guy lets just say his name is Bob. I sat by him and his best friend in Computer Class and he would be teasing me and so would his "BFF". Then we got moved and his BFF is sitting a few computers down from us and me and Bob sit next to each other and now he still teases me and he's really sweet. Sometimes I'll catch him staring from across the courtyard. So does he like me?

Probably.

Only he knows how he feels. Why not ask him?

Well, you haven't given that much information so it's a Bit hard for me to tell. If a guy is staring at you it can mean two things -either you're hot or he has a crush on you. I'd say he probably does like you -apparentley guys often tease girls they like, so all the signs are good. Just be careful not to go assuming too much, it's a big mistake. He still could just like you as a friend. Aww that is so sweet. Its always such an amazing feeling when by some coincidence you get to sit next to the guy you admire :) good luck sweetie :)
