One thing I've learned, when wrapped up in a drama-filled situation like I am that is emotionally intense over child custody - DBing is futile. Maybe just because it is a personality disordered individual. But dealing with W or her family is an exercise in futility.
I think you have done great through all of this. You don't really know it is futile. Who knows how bad it might have been, especially for you, if you didn't DB. I kind of see you as one of the better at this stuff.
