I left my not-so-DH of 30 years recently, always been a difficult relationship but enough good things in it to make it worth while, and I loved him. But the last 5 years, he got more moody, bad tempered, controlling, and when I retired 2 years ago, it all got much worse. Finally I left, and his anger and desire for revenge has caused me and my family (brother and sister) lots of problems, all very nasty stuff, he is still playing mind games and trying to control me from a distance. So much so that I have had to get the police involved. A wonderful woman police officer really opened my eyes to how unacceptable his behaviour is and was - because over the years you just get used to it, make allowances to avoid arguments and gradually lose sight of how unacceptable things have become. She recommended a really useful website called the Freedom Programme, where you can get a book called Living with the Dominator - sounds like it describes your husband, Chris. I found it helped me to get a better perspective on things - what is normal and what isn't, how someone can manipulate you, and how we can sometimes collude in letting that happen.
Only you can decide what is the right course of action for you, but understanding the problem is him, not you, is the first step in working out what you want to do about it. Good luck, whatever you decide
