hbb, i think letting go, as painful as it is, is the only way for you to move on and really see the whole picture. i'm willing to bet you (real money!) that a year from now, if you haven't had contact with him, you'll look back on your relationship with him and wonder why the heck you held on for so long. you'll wish you would have let go sooner. and most of all, you'll see that you really didn't want to be with someone who treated you badly (or less than what you deserved). you'll see that he did you a favor.
it all just takes time and distance. letting go is hard and painful, but it very well could be the best thing you've ever done for yourself.
