Thanks for checking back in, as I do remember your story.
Do you think it is possible that your AH is bullying you when he threatens to fight you tooth and nail for the children?
I was bullied by my AH over our personal property, which I was willing to walk away from. It turns out he was bluffing and didn't even hire an attorney to contest the divorce.
I agree with your attorney ~ I doubt he will have a chance given the history of rehabs, relapses and medical documentation to prove his struggle with addiction to alcohol.
Sending you encouragement and support as you continue to take healthy steps for you and your children.
