Wow. You need to be a bit thick skinned BS to post here.
I'll try not to say what's right, wrong or normal, but just tell you a bit about my experiences post D-day.
I had been with my wife for 27 years. Never strayed, but once in a while thought about how it would be to have sex with other women. It was a close call once, but I never followed through because I loved my wife, and I didn't want to lose what I had with her - especially after we had kids together. After the close call 20 years ago, I never let any woman come too close to me, because I didn’t want my loyalty to get tested again.
Two years ago, I discovered her 9 months PA, and it was the most indescribable experience and pain I have ever had in my life. Emotions exploded in my head the following weeks and months. At the same time my wife tried to tell me that she only wanted to be with me, that she loved me, that what we had was something very special etc. Do you think that I believed her? Not a chance. I felt worthless, useless, used, tricked, double crossed, unattractive, abandoned and a whole bunch of other feelings. It was absolutely horrible. Self-esteem and self-worth was completely destroyed.
I did what other BS above described – I worked very hard on me, getting in better shape, lost 40 lbs, changed appearance – mostly to win her back, but after a while it also felt good when other people noticed the changes and complimented me. You may call it wayward thinking or not, but I needed that very badly at the time – not before, not today, but a few months after D-day, I did.
My wife even tried to convince me, that it’s perfectly normal to love more people to justify herself and prove to me that she never stopped loving me during the affair. She gave me a free pass to try for myself, because “she wanted me to experience these confusing feelings while still loving your spouse”.
She also wanted to feel what it was like to know that I was dating others, would she feel jealous or would she not care? – it would be a way to decide if we had a future together, she said, while considering open marriage, so she could continue seeing her AP.
So I started dating (makes me a madhatter?), I thought that since my wife had changed the rules, I had to learn to play by the new rule set. What I found out was that I had no problem at all finding other women who wanted to date me, also a lot who told me to call when I was single again.
From that day, my wife has never mentioned anything about an open marriage.
I know from what I have read above that you’ll flame me, and go ahead, have your shot, but I’m actually happy that I did it, and I’ll tell you why. It rebuild my confidence and sense of worth. And my wife suddenly became aware of the fact that she might lose me, something she never thought about – she took me for granted before and during her affair. She’s aware of that fact today and it has been an important factor in her decision to change.
I don’t regret it.
My story may not apply to OP, but I could see myself in your BS' beaviour, flip-flopping between staying, leaving, redefining rules etc.
