What would you do?

I'd tune him up first, then tell him if I get another report
of him being a asshole to his wife, I'll be back with the authorities , get a restraining order, and see if we can't get court ordered medication, therapy or nursing home for violent people.
Don't make threats, do it, burn his ***.

Should have happened a long time ago.

I agree. You've got to stand your ground against abusive people. They are like ticks. They find a nice, cozy place to dig in and infest your life and you don't want to deal with them initially, because they are a pain in the ***, but you can't just continue letting them leach off of you.

I'd basically dismiss everything he says. What the hell is he going to do? Fall on you? Leave it there. She lives there. Let him call the cops. They will do exactly nothing about it if she is okay with it being there and the cops will likely see what a dick he is, just the same, after the situation is explained to them.

I throttle people like that.
