I'm confused on my feelings for him

well, I met this guy(let's suppose he's A) about two years ago. He used to come to my class. He told my friend to introduce him to me. That friend didn't. But he came to my class during lunch break and talked to the guys in the class. At the end of the first year, he vanished. Then the next year came and he and I were in the same class. He threw things like papers, erasers at me, just to get attention from me. he had a crush on me. Then his friend(let's suppose he's B) had a crush on me. Then, they didn't talk about his crush anymore ( well, they just didn't talk about him much). They talked about his friend's crush on me. I got a little interested in his friend too.But I couldn't forget him. but I didn't love anyone.
Then, his other friend( let's suppose he's C) talked to me online and we became friends. I gave a present to C. And the next day, most of the guys in the class were talking about me and C falling in love. But I didn't love C. I don't feel anything about C. Then, the school's over. Then, summer, A got my phone number from C and we talked. But he just talked about other guys being in love with me. he said nearly everyone was falling for me. He sent messages to me. but never called me. I called him after he sent a message to me. he talked to me cheerfully. And then, one day, he joked that he was tired talking to me. so I hung up even before he finished the sentence. I was calling him just because I liked him, not love. and just because I thought he wanted me to. Then a few days later, he sent a message to me, "hey, where are you now?" at 3:00 a.m! I wanted to reply to him but what he had said reminded me that I didn't need to reply to him. he had said, he was tired talking to me! Then he sent another message, "Hey, girl, where are you now?". I wanted to reply to him or even call him.. But I don't want to do so when I thought about what he said. now, I and B are in the same class. and I still talk to C. But I don't call A anymore. am I just overreacting? should I call him back? and what is it that I feel about him? I'm sure it's not love. and I"m sure it's not crush either.
Thanks you for your time.

Well, I think you should talk to 'A' again. Maybe he was just kidding, he obviously wanted to talk to you because he e-mailed you... so give him another chance. I can't tell what your feeling, seems kinda like a love/hate type thing. Maybe if you talk to him again you will figure out your feelings!!! Hope things work out for you!
