Better off as friends

I've only met him 2 weeks ago and already he's turning me down. What did i do to him? I thought he cared for me . There could be maybe 1,000 reasons why he left me. ( I won't name all of them) But if thats the reason he probably doesn't respect me. Why did he leave me? Maybe because he told me he loved me, I never told him anything back. He asked me to be his girl, I told him it was to early for that. He asked me to meet his parents. I told him i wasn't ready. He called me and asked me to go on vacation with him, I told him " I don't think we should do that". I told him he was crazy. I don't understand why he wants to move so fast. All i wanna know is why is he turning me down? I thought he was cute but never really had the time for him. I cared for him for him but never really had the time to tell him. I wanted him but never told him i was feeling him. Maybe weren't only meant to be friends. I guess when he calls me later I'll have to tell him how i feel. But i still think we should slow down. But wait will he still be turning me down. My only question is "Why am i turning him down" in the first place.
