Most Helpful Guy
I see. If you date an ex, make sure you have addressed what went wrong the first time, otherwise you risk breaking up again, like this time.
He isn't disappointed with you. He shouldn't have handled it that way. Apparently he isn't comfortable with dating a girl that has been with other guys before. That would definitely make him uncomfortable if he isn't good at relationships. But he shouldn't have broken up with you just because he wasn't good at it.
Talk it out. He just isn't that confident in being able to handle you having been with other guys. Don't break up so easily in any relationships. Talk things out before it gets to that. It seems like he likes you, but perhaps he thinks that you have done some things with other guys. It might be based on rumors or truths, and you won't know unless you ask him exactly what it is that he is not comfortable with.
