So you're dealing with a conflict avoider. Well no wonder he frustrates you. You need answers and he leaves you hanging. It's so hard to live like that under any circumstances!
I'm sure your ex's e-mails have something to do with your mood. I always do better emotionally when I have no contact. Having to deal with them brings the pain back to the surface and that sucks! Your also right about feeling like this isn't happening. I used to think that this whole divorce thing was so surreal since it was the last thing that I ever thought I would be going through. All I can say is that you do make peace with the situation, and although you still have the memories to live and deal with, it does get easier.
Besides, you still have your whole life ahead of you and I know that you WILL be happay again!
