In my limited male experience with fellow men they'll tend to do shit to get a reaction but only of they feel they can get away with.
If he is a nasty drunk with a bloke that looked like Tyson Fury he'd likely get his head punched in, so he wouldn't get away with it so doesn't do it.
If he gets abusive and dickish with his OH..... Who keeps forgiving him?.... Then he's getting away with it and will continue to do it.
I actually think it's quite a common triat in a lot of people, men and women, they do things solely to get a reaction. Like kids I guess, pushing to see what they can get away with.
Like OPs OH, "I'm depressed and bored."
OP should have said,
"You know where the door is cock face, don't let it hit you where the good lord split you" then gone about her life as normal.
He'd either have left, problem solved, or realised OP isn't going to put up with his shite, problem solved.
That's my no cents worth.
And EVA, walk through your front door and keep going till you find your arse is somewhere much better
