Entitlement mode, yes, I remember something like that. I wonder what I've forgotten about this stage. What should I expect?
I know a lot of hostility, rewriting the past, demonizing me. He's passive aggressive so I expect silence, little jabs. He's going to be blaming me for "ruining" it for him right now, and he's hurting that he found out that OW is seeing another man... although she may have been able to explain it away by now. Who knows how deep she is with him. They both may be explaining it away and believing each other. No worries, the doubt is there and will fester. They can't be in an infidelity situation with full trust.
I just hope he doesn't get the children involved. I've been able to explain away most of what's going on, but I don't want to hurt them. I know how much pain they're already in with other things going on.
