Con man seems like a perfect description. Not only has he weasled a way to get back in the house daily, but now he's staying there. So, he gets to verbally abuse you, in front of the children, because you don't trust him alone with them, but can't see your way clear to limiting their time with him.
I'd say, he's got you exactly where he wants you, and it sounds perfectly miserable.
