One worry about this that struck me, is fear of black/white thinking, perhaps? My exh had a way of demonizing anything that he heard about my childhood. Oddly, he's come to terms about my father, my father's personality, etc. Sees him for who he is. He's actually been decently supporting if I need to just make that call and without getting into details, he knows what to say. My exh with his mi, it would be natural to black/white the situation. Anger management, may have played a role in his way of relating.
