Part of the problem is that I haven't been sleeping well for the past week. I'll go to bed soon and hope for the best.
Yes, closure... I think we sometimes think we got it but we didn't. Not yet. It takes lots of time.
In your situation I will repeat what I said earlier. Divorce does not bring closure. It really is just a piece of paper. For me, though, it meant the end. The end of a R. The end of communication. This was good because I was still tring to get him to "get it" and he never would.
I hope you find closure too. Do for yourself and your kids. It is always the right thing to do.
