I've dated this guy for 2 weeks and last night he told me that we shouldn't go out anymore.I was shocked at first, then started crying for almost an hour-in front of him. I had pictured that this could be a good long-term relationship, but now I realised that all is just my own thoughts, not anything mutual. He said there was no sparks between us, and the way he saw relationship was different than my point of view, he also said that I'm too young for him as a girl friend(18 vs 22)-he felt like he was an older brother sometime,which was not what he wanted. Honestly, I thought he was a very attractive guy, but I didn't like him that way until 3 weeks ago at a friend's birthday party that he was trying to flirt with me, and we finally kissed, which got me this strong feeling towards him. But why did he give me this feeling and turned away all in sudden? I know that i can't force anything to happen if that's not what he wants, and I'm on the positive track to get over him now, but it's just this little part of me that is always thinking about what I could have done that would have kept the relationship, and I just can't stop thinking about him. It seems like everything in my life is not going well right now. I don't know what to do.
