I'm hearing you on this and came to similar conclusions. He has said in the past that he wishes we could be friends, that I would accept him as he is, not as I want him to be. For now, I choose not to. I don't want to be friends. I can't pretend that everything that happened, everything he said and did, doesn't matter.
I didn't clean the house for him (he wouldn't come in, and I knew that- he called S on his cell phone and the kids met him in the drive, which is usual.) I cleaned the house because it had to be done, and I am on my own, and I have to be able to do this.
