Problems with this guy in my class

ok well I have this guy in my BCIS class. and his names kyle and hes in 11th gradee. and im in 9th,and I really liked him and yeah I still do but a couple weeks after school started we started talking to each other over myspace and he asked me if he could take me home everydayy- and I was like yea. and we talked about being a “couple”. so we did that for about 4 days and all we did was makeout but we spent so much time together during those 4 days. and he was like “ iREALY like you and I want us to be together for along time” so I was like ok. and a couple days ago we were talking about my parents likeing him and he thought they didnt because they found him on top of me a few days before. and so he told me if it didnt work out between us- he had another girl to go to that was in 11th grade and her parents loved him and I was like ok? and I got realy madd. so he was like” ok shelbie I like you more tan her and I havent done anything with her” and I was still mad so he finally said” if your going to be mad at me I just think we should be really close friends and I dont want that because I REALLY likeyou” and im like” no I dont want to be your friend at all” so I still like him and hes been asking to be really close friends still and I dont want to be but I do because I still have feelings for him. but my question is do you think I over reacted to him having a “back up girl”. and should I be friends with him or just try and forget about him
