I get scared at times of threats made by separated AH as well. As recently as yesterday! Then I remember he always makes threats. I spoke to divorce atty yesterday and felt good. I do not have extra money for attorney but I found a way.
I had to take back my power. He cannot get to me anymore.
If your family is doing anything inappropriate or against the law, you cannot control if they have to reap consequences of that. I know you want to protect them but you have no control of that.
My separated AH quacks a lot and I am just recently learning not to take him seriously.
