Forget about his anger. Unless you know you were a bad wife, that's just a smoke screen. They feel bad FIRST, THEN they go looking for an explanation and start picking apart the marriage. IMHO, it just plays into their craziness if you start believing everything they say about how "terrible" the marriage was.
As for the questions - next time he says it, I'd ask him "What questions do YOU think I shoud be asking?". Could be he has something he wants to confess. Or maybe he's just fishing for an invitation home (don;t give it to him - he should come begging!).
