Yes to what Shining said. YOU don't break through his anger and resentment. You let him figure that out and detach. Detach. Detach. He's far from figuring out his stuff. Give him lots of space. He is still on a roller coaster that you don't need a fast pass for. Nope.
I'm not a vet, however I can see this. It sounds like Clarke moved back in and he's still the same. Focus on you and the kids. Let him work through his stuff. Be cordial and friendly neighborish.
Hang in there! You cannot fix him or *make* him do or see anything. Hope you have fun stuff planned for the weekend:-)
