WTBH - nice to see you again. So sorry it is with the same old song and dance. He really is a piece of work, eh?
I am nearly ready to say he can just have whatever he wants.
I understand this. So what is it he wants so badly? If you can, give it to him. Give it in spades, so much so that he chokes on it. Does he need to be right? Agree with every stupid thing he says (just not in writing!). Does he need to be validated? You can give him that without admitting to anything. Divorce sucks, for both of you.
You know your truth, WTBH. Don't ever forget that.
So what can you do to manipulate the situation to get what you really want...to be left alone?!
