Have you come across the term 'Cheeseless Tunnuels'?
It refers to doing the same thing and getting the same results, each and every time. Rats in a maze won't go down a tunnel that doesn't have any cheese because it is pointless, yet we do, we repeat the same pattern hoping that there is a reward.
The way you interact with your wife, produces the same results, everytime. If she isn't going to change, then you need to change some aspect to get better results. I am not saying change you, you aren't ready to hear that yet, I am saying change something, positive, about the way you interact with your wife. And maintain that change, because the second you go back to the old way your wife is justified in not believe you.
