How can I fix our relationship?

Last year, I moved to a new high school and immediately became friends with this guy. As time went by, I found out that he went to the church down the hill which gave us more topics to talk about. I couldn't remember a day that I didn't talk to him on either text or facebook. We started being really close friends and we hung out almost every weekend but it was only a friendly friendship. I knew almost every aspect of his life except I couldn't handle his basketball friends. They were complete jerks. However, I soon realized I wanted to be more than friends with him. As a normal girl, I basically told all my girlfriends that I wanted him. Near the end of January, I told him that I wanted to be more than friends at a group outing. His response wasn't what I hoped for and after I told him, he didn't talk to me for almost a week. It was unbearable. During this week, his bball friends found out that I liked him and told me that the guy I liked wouldn't shut up about how he liked me. They even invited me to hang out with them when they weren't balling and I did but the guy I liked definitely did not act the way he would be with me alone. We eventually talked again and I asked him to spring tolo; but we ended up not being able to go because I got the swine flu 2 days before. Tolo was really close to the end of the school year and soon came summer. We didn't see each other the whole summer because we were both always on vacation. When school started again, I told him I missed him and he felt the same and we started to talk gradually. However, our relationship is definitely not the same from before. So much time has gone by; I don't even like like him anymore; how can we just be good friends again?
