Exactly what I'm talking about. He can control it
when it's to his benefit to do so. Your parents were there, he needed a place to live, he controls it.
When it's "only" the woman he professes to
love, though, it isn't controlled. You "push his buttons" so it's OK for him to be hostile, violent, and threatening when you do something he doesn't like, doesn't approve of, or is irritated by.
We all get angry from time to time. Some of us more often, or more easily, than others. But we don't become violent. Therein lies the difference.
