The guy I hate kissed me. I’m so confused.

Or thought I hated, but now I’m not too sure. I’m posting on this because I really need some actual opinions, instead of my best friends who basically screamed like fan girls when I told them. I’m 17 and pretty unexperienced in dating, but I’ve hooked up with a few guys before. Just no serious relationships. So I met this guy at the start of my senior year which was like early September. I was on my way to lunch when I saw him giving crap to one of my friends so I went up to them, snapped at him and gave him the middle finger then took my friend away. I thought that was the only time I’d ever see him because we go to a big ass high school but now he’s in one of my classes, just my luck. Anyway, for pretty much the whole month of September up until last week, I’ve had to deal with his constant jokes and picking at me all the damn time. I can’t even list all the things he’s done to me or else we’d be here all day, but any rude remark or prank you can think of, he’s probably done it. I just kept on trying not to let it get to me so whenever he would do that, I’d give him a cheeky smile or stick my tongue out and flip him off. This seemed to work and I thought he finally took the damn hint to leave me alone, until this Friday when we were walking down the hallway together (don’t even ask why, bc i couldn’t even tell you). He seemed in a good mood and I thought we were finally getting along, so I casually asked about one of his friends who I sort of have a crush on. He basically looked at me and said that I’m not his friend’s type so don’t bother. I don’t know why but out of all the things he’s said to me, that hurt ALOT. That’s when
