It's great that you refused to talk to him when he is angry. Keep that up. Nobody deserves that kind of treatment.
It seems both you and your H are very upset and volatile (especially he). That's how it was for me when the whole thing first blew up. I think things will settle and calm down a bit.
I hope you'll take a broad, wholistic view at yourself and the marriage. Your marriage has been unhealthy for a very long time, it sounds like. So it's not going to get better overnight. Like they say, this isn't a sprint. It's a marathon.
Funny that you say he's a weight lifter but he hates people looking for attention. Weight lifting seems inherently ... well, it's about looking a certain way, no?
Do you think he's having a midlife crisis?
