I agree with Sojourn and emphasize....just let it be. If he contacts you, then it was meant to be...if he doesn't, then you may be better off for the lack. In any case, don't beat yourself up, and don't tear yourself apart trying to figure out what is wrong. Thats a mistake lots of us women make...over thinking. It's not your issue. It's his.

Take care of yourself, as Sojourn said; don't allow yourself to become a doormat for him to wipe his nasty emotions on. If you create boundries now, it will pay off in the future whether that future is with him, or someone else.

Take care
