I had to check your name to see if my wife was posting here! There are that many similarities between your H and me. I often hope that my wife's true feelings are to stay strong about the D just to make sure that my changes are real and permanent. The uncertainty from my point of view is tough, but keeps me strong and motivated to make sure I forever give my wife the unconditional love she deserves and I have for her.
My two cents for you - real change is possible, as you know. Even though it hurts me to say this, you need to play it out to make sure that your H is truly changing for the better. Us guys can be pretty stupid and slow, but we can also make remarkable, permanent turnarounds! I hope for your sake that your H is on this voyage of self-discovery and improvement.
