I just wanted to stop by and wish you luck at the attorney. I think you are doing the wise thing by protecting yourself and your S.
MLCers are unpredictable and the things you thought your H would never have been capable of pre MLC can leave you spinning if you are not prepared.
The selfishness and entitlement on their part can be jaw dropping and some LBS don't prepare in time.
Good on you for getting past the shock enough to realize the sooner you circle the wagons the better things will be for you and S no matter the outcome with your H.
