Please, please don't give it one last try.
You are wasting precious years. Do you want a family, children, to enjoy life? You won't with him. You will continue to be as you are now. As was his first wife.
Is a life of constantly battling to stop the person who is supposed to love and support you from grinding you down, a life worth living? Is it any better than what you have now? No. It's the spirit behind it all that matters - that won't change.
Just be very very glad you have strong finances and no children, and please please walk away and save yourself. For YOU. Because you can be happy, free, you can have love and care and true happiness and freedom.
The reason you are here asking these questions and haven't walked out the door yet is because he has ground you down to a position where you feel you have to justify having feelings at all. Please see that that's NOT REAL - the reality is, when he tells you that there are no problems and you need to try harder, a normal response is 'No, you are wrong. There are lots of problems. It's a shame you can't see them, but they are there. That's why I'm leaving - because I don't want to be with you any more. Marriage vows are only for life if it's a good, mutually beneficial, loving life. It's not with you.'
Those sentences are normal, acceptable, understandable to anyone in the real world. You said upthread, you have almost lost your sense of self. While you can still see that, GET OUT.
