My mom was told numerous time to leave him, since he was so abusive towards her. Family and friends would offer to let us live with them until she got back on her feet. She always refused because she was always afraid of him.
Yeah, anyone who is so controlling that they attack other people's wives simply because they liked some video that they disagree with is controlling, and if they try to be that controlling and bulling with other people then god-knows what they are doing to their wife at home.
I doubt he's a loving, respectful man in private given what he's like to other people in public.
I don't know why women in situations like that don't leave, life is never going to be great if you have a loser in it and you have to think about what is best for the children.
