Just a thought...I played way too "nice" in the beginning, didn't get financials hammered out or personal items in the garage etc. Had there been young children I probably wouldn't have set up a custody agreement. I thought he'd come to his senses and come home. Guess what, 10 months later, still gone and all that little stuff is a bone of contention and can allow resentment to creep in. You can't work on being your best you when you are constantly pissed off at this stuff.
Setting written boundaries doesn't have to be mean and nasty. It might be a painful but doing this could save you from more pain down the road. It's like constantly knocking the scab off a healing wound.
Remember in their minds, these guys are GONE! They have made their choice. Let them be gone but protect yourselves and your children.
I read the Munson book, it's been awhile, but IIRC she had a written agreement.
They aren't making it difficult for you to detach, they are doing what they feel is best for them, which is what we should all be doing.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
