Benson,
I remember you sharing some of this some time back about the daughter and girls. Praises to Him who can do All for helping your daughter remain sober. It often takes a few "reality checks" for folks to make it permanently sober, so don't give up hope there if a crisis throws her for a loop momentarily.
I echo your prayers, for your ex-wife, her healing, wisdom for the courts in helping place these children of God, for your ex's family's growth in wisdom and grace and for your own growth.
You were there for me always throughout my own trial of 29+ months...
If you meed more'n prayers, shoot me an email and we'll set a time to talk by phone.
Perhaps you could, (just a thought) take a quiet moment in prayer and even though out of state, open your heart to the judge, etc in a letter.
Prayers up!
