*disclaimer* I don't really know anything about spousal abuse or hormonal imbalance. But I'm intimately familiar with uncontrolled outbursts of anger. So if it seems like i'm "taking his side" or trying to talk you into staying, I'm not. It's just what i see when i read your story.

He needs real therapy, maybe he hasn't dealt well with the trauma of cancer or hell it can be anyone of a thousand things but it is definitely not something you cannot fix alone. If he's externalizing blame to this extent then he's not going to listen to a thing you have to say. So long as he maintains this cognitive dissidence which absolutely blocks all attempts at introspection he will never ever get better, he can only get worse.
The brain sets up blocks like this to protect against shame and hurt, introspection and any kind of valid criticism feels like touching a burning stove you just reflexively have to escape from it. It takes a trained professional to defuse that reaction and until it's diffused nothing can be done to help him.
Quote:After is over, he pretends like it never happened...."I love you! Can I get a kiss?" ...
In my experience rage gives you unshakeable certainty, when the anger drains away the certainty goes with it and you're left standing there wondering why the fuck you just made those choices. you're left scared, confused and ashamed and often physically weak. It's a complete 360 mood swing. Personally I used to cry and try to crush a pillow but i can easily imagine that if i had a SO i would have clung to them like the last lifeboat on the titanic.
Quote:I just wish someone would say, "You have done all you can do...".
It is absolutely not your fault but you trigger negative emotions because you make him feel ashamed and trigger that knee- jerk reaction,
you cannot be the one to help him. Until that cognitive dissidence is repaired
He needs a therapist's help. Even if you leave him, please urge him to go get help ASAP.
