Tyran,
I get the feeling that you are not hearing what you want to. I think that you do want to see him. Think of it this way, if it is meant to be it will. Something will happen and you will get the oppertunity to see him again. If it is meant to be. I wouldn't chase him. Guys don't like that. They want to do the chasing. So I agree with the other, I would let it go. And just see what happens.
Why do you assume that you did something to cause the break up. Maybe he just decided he didn't want to be in a relationship. But didn't have it in him to say anything to you. Obviosly he didn't tell you anything, if you don't even know the reason that you broke up. I understand that you want answers, but if he is saying bad things about you, he isn't worth your time. Find somebody better. Somebody will come along. This is just the beginning of relationships.
Best wishes,
Hugs, Karen
