EXACTLY!! I was trying to make the point that we should not assume that there was a lot of animosity between them or that he was the violent type who would go into a jealous rage and kill her. If there was any violence or abuse in the past, I don't believe she would have stayed in their home, she would have left as soon as she filed the divorce papers, if not before.
Some women who are victims of spousal abuse often stay with the husband out of fear or the belief that they have no choice, or threats of harm if she leaves. This does not appear to be the case here. She was going to divorce him for the 2nd time... doesn't sound to me like she had any reason to be afraid of him, she went to a party without him. Sounds like they had an amicable arrangement to me. For all we know, they may have had an agreed to take turns going out and the other staying home with the girls.
It's fine to have differing opinions but inventing theories and then bolstering them with nothing but speculations is a waste of time, IMO. He may turn out to be an axe murderer but there have been no facts to support that theory that I've seen so far, maybe I've missed something?
Even the nicest people, with no animosity in the marriage, manage to find rage when faced with a crumbling life.
Let's not invent theories about men that are friendly during divorce.
