Let him be furious. That's his problem. You cannot force others to talk to him.
When mine whined about how much it hurt him that my dad now shunned him, I told him straight up, that's a consequence of of his actions. I said, did you really expect to hurt his daughter and grandkids, and still have things be the same between you? Maybe you should have thought about that before you had the A.
Honestly, I know you want to keep things "good" during the divorce proceedings, but you can't control how he feels, or how your parents feel. He should consider himself lucky that they don't cuss him out every time he's around!
Your answer: I'm sorry you feel that way. Don't try and justify anything to him.
He is no longer my best friend. Repeat until it sticks.
