Mine wasn't angry with me bttrfly, only chronically dissatisfied with life. His inability to be happy manifested in many ways unrelated to me:
- constantly planning his next big adventure because he'd get depressed without something to focus on in the future
- getting in trouble at work because he couldn't be satisfied with his great career and his great job with exceptionally good hours for a surgical specialty and good money and national prestige, and because following the rules was beneath him. They even sent him to anger management once.
- constantly remodeling, even things that didn't need it (this has been even more of an issue since the divorce, when he has remodeled a single room with bath 3 times that I know of in ten years. Not redecorated, remodeled).

I contributed a LOT to him staying relatively sane and happy during our years together - I doubt he could have been married to anyone else for 24 years as successfully. But his inability to be satisfied also led to cheating, some of which I had no clue about at the time but that seems pretty clear now.

And bttrfly, if he never wanted the divorce then I guess he shouldn't have carried on a years long affair behind your back, should he? You didn't cause that. He was probably just mad because he wanted to have his cake and eat it too, and you ruined that when you figured out he was having an affair. Poor baby - he had CONSEQUENCES! And he didn't want CONSEQUENCES!
