Grace said exactly what I was going to say about him coming and going. It is no longer "his" home since he chose to leave so he does need to call before coming over. Setting up a schedule to see the girls is a great idea. Then everyone knows what to expect. He does need to feel the consequences of his choices.
I suppose he will get angry if you set this boundary but since he seems perpetually angry anyway . . . he will get over it.
Having him not be able to just drop by unannounced and a set schedule I would think would help stay dark with him.
