Alexisk17 had some comments that make me want to clarify something.
...I don't think it should be done to the WS with the intention of tit for tat.
...quit his job, never visit with his friends, sell the house, buy a new car, etc.
In all of the things that I listed, my wife didn't compel me to do any of them. Not one thing. I had some choices to make and some of them would have not been compatible with staying married, but those would have been organic results of my actions, not emotional extortion.
The house was going to be sold anyway. We were either going to divorce or move someplace together. The car; she just finished her Ph.D. and needed a car for work. We worked together to get her the right one that would make her happy. The house proceeds were about her safety and investing in our lives together. Working from home was a positive thing of keeping my job when we moved. Separating from the friends and hobbies were about having a healthier life. She made many of the same changes too. It wasn't unilateral.
My BW has been justifiably angry after my affair and is not the kind of person to hold back. She has expressed every bit of hurt and fury that she has wished to but has not ever in the course of this coerced or punished me. I'll tell you straight up, if she had coerced me, then the work that I have done wouldn't really be -my- work.
(An aside, setting firm boundaries about what is acceptable and stating deal breakers is not the same thing as coercion. I always had the choice.)
We both believe that Waywards need to feel the pain of what they have done. It's part of ownership and growth. If you don't know the pain of infidelity and do your best to understand the consequences, you won't learn and won't fix your problems. However, not once has she inflicted gratuitous hurt on me. There were plenty of times that I thought my world was ending in the past year, but every piece of it was a legitimate outcome of my actions, not spite.
I chose these things. Transfer of power for her safety, acts of contrition, cutting out toxic activities, making positive life changes. It's not like it was easy and it's not like I'm Mr. Virtuous. These are my decisions and I'm at peace with them, unlike the decisions I made during my affair.
