If there isn't already a book with a similar title there should be because this is essentially what happens a lot of times.
I'm only 2 months into R with my wife after she had an A. From my knowledge the OM is out of the picture and I'm pretty darn sure the A is over due to some extensive detective work over the past 2 months.
What is left is a much better me as a husband. I'm actually now the husband she has always wanted according to her. We feel closer and I have to say even though the sex is awesome I don't feel so dependent on it like I did before. Yes it still hurts but I feel more in love and the feeling seems mutual.
So I'm sitting here thinking to myself...she was unhappy, had an emotional affair that turned into sex with OM, and now I have given her a better version of myself. It just seems really strange to think about. If I had cheated on her I'm pretty sure we'd be split up right now. How does she get to have sex outside the marriage and now almost get rewarded for it? I'm not saying I feel it's unfair or that I want to get revenge but it's just odd how things happen sometimes.
I know I'm probably over thinking but this is what happens a lot of times. It almost makes me wonder if it wasn't all planned. I mean hell, if you aren't happy you might as well cheat and see what comes of it. Either they leave you or the marriage becomes better. Sure there are still bad days, and I have zero trust for her and she knows it, she has to check in with me all the time, and be transparent but things are much better than they were before the A happened.
What a roller coaster infidelity is.

That or God just has a real sick sense of humor I guess.
