Oh, I saw the play Menopause!!!! If you haven't seen it it's definitely something to go to with a group of middle-aged women or their spouses. Really funny!
I think you are successful if you can grow, become a better person, and avoid bitterness regardless of where the relationship goes.
It sounds like a wee bit of friendship with your wife, and at this time after all that you've both been through, that's a good place to be. Little tiny steps...
"Coming back" is too general a goal. You need small, realistic, specific ones.
There is no arriving, ever. It is all a continual becoming.
