Boundary idea: Don't let him into your house during drop-offs/pick-ups. He certainly shouldn't be kicking his feet up like he lives there. I did this with my W non-verbally (I stand at the front door during drop-offs).
Regarding the bonus, is it possible you are entitled to more than what he gave you?
I think anger helps a lot to get to the business mindset. It's not that easy to just flip a switch, hang in there.
