Gr8ful,
My goodness. It’s your life and have every right to do with it as you please, but from the above it sounds like you utterly discarded all that made you YOU,...
Yes, and yes, and I am Gr8tful that I did.
...all to transform into whatever you thought your wife would like more. 
No, not at all. Though it was important for me to try to understand what my wife wanted of me and from me, I made the changes for me.
Sounds like you discarded a relationship with your Creator as well for this woman.
This statement is a little tricker to delve into. I do not wish to sound as if I am challenging anyone about their chosen beliefs. 
1st your thought proposes that a "creator" does actually exist. But, for the moment we will work with that assumption. I did not give up my Creator for "this woman". Before I explain, it is imperative that I ask a favor from you.
Please, do not refer to my wife this way. Call her your (my) wife, call her a wayward, I’m good with that but she is not to be devalued on any of my posts by calling her "this woman". 
In past posts I have referred to working full time in missionary work. I loved and was fully committed to the vocation for I believed I was "doing the Lord’s work". But parallel to my labors, while living away from "my people", amongst people with an ancient faith, I began to question the arrogance of the more modern, Americanized church I was working within. I started to question my thinking that believed my faith had everything right and theirs was evil – a fight against the real Creator. This is all a few years before my wife began her 1 ½ year affair and it would be 5 years later I’d be listening to a D-day moment. So no, I did not give up my Creator for my wife, that process had already been baking in the oven, in my head.
At the time of D-day, even though I had moved away from believing there is only "one way", (Conveniently, "my way") for God to be in one’s life, I had not given up my belief in a Creator. My wife and I were still fully involved in church work. I was the youth director/minister in a rather large church, and my wife was the organist and coral director. Her affair partner was the fulltime choir director. So, when the affair came out from the church’s shadows, having it so close to home, did give me pause and I began to pull away from my church and my church family. That said, I did not leave God behind but my faith in his presence and goodness was under challenge. It took a couple of years post D-day for me to conclude that I no longer believed in a higher power. Which had nothing to do with my wife’s affair. My wife kept her belief, and she was still playing the organ, though at a different church. I never once tried to persuade her to believe or do otherwise. It took her another 2-3 years to conclude what I had a few years earlier, and she resigned.
I hope that gives you a better insight into my lack of belief.
Looking back at your life, are you pleased with the results of your total transformation into a different man?
That is a fair question to be proposing and an easy one for me to answer for I often review my decision to not believe, for the consequences of being in error could be grave. The answer is a firm - YES! I am far happier, more empathetic and open to others who view the world differently than me. I no longer look through the closed lens of – good verses evil, sin verses righteousness. I’ve come to believe the world, people and actions are far more complex than the simplicity I was operating my life under.
Thank you Gr8ful for your questions, concerns, and insights
