I'm sorry to hear that cbtdad... I had high hopes for you.
It always seemed that your expecting something from her always got in the way, I hope that you've really come to terms that she won't always do what you want and have stopped expecting things.
I wonder if there's anyway to follow through with your current plans, figure out custody and separate, but shelve the D for now. She's been going through schooling, you've been trying to deal with her past A which was made more difficult with her focus on school..
Maybe time apart when life is back to normal will change the feelings for each other, maybe not, but there is no hurry to D unless some other major life change dictates it.
