I am naturally drawn to your post because this is the order of events in my marriage too. I had an affair with a man old enough to be my father. I confessed and he had his own affair 18 months later that he as longer, and worse in details. But my worse is I am the one that lobbed that bomb first.
I found out, and like you he decided he wanted to work through it.
I imagine what you say can happen here to us as well even though from my perspective we are closer and more connected and have a great friendship to boot. But I am so aware that he has avoidant tendencies too or he would never have chosen an affair either.
I think maybe just sit and talk with her about what you are feeling. It is absolutely what I would want. And remember during that discussion that:
1) both of you were likely trying to solve pain by using escapism in the affair. Your pain was from her affair but do not disregard the possibility pain she was in was equally hard for her to cope with. It may not have been caused by you, but whatever it was felt real to her.
2. She probably doesn’t give a shit about his size. An affair is usually had by two people looking for validation and feeding the other’s ego in order to keep the validation they want coming. An affair is most often a sick thing where you pretend the other person shits rainbows because you need them to be "wonderful" because if they aren’t the attention they are giving you is not as valid. You are each others hype person yet you know limited information about them as a true romantic interest. Even if you knew them a long time. I knew my ap for years, it didn’t mean I knew him well enough not to super impose my vision of who he would be. Women especially cheat for these non realistic romantic fantasies and then we realize we are dumb as hell and the real romantic vision was always there in front of us. We didn’t appreciate it enough. My husband has always been there to take care of me when I am sick, makes sure I have the right coat or an umbrella, he is my whole history, my family. My pain blinded me from that.
What I am trying to say is that there are likely a lot of similarities to how she feels about her cheating and how you feel about your own. There was likely no real love (I professed mine too) but an addiction to the dopamine the affair was creating.
Have some solid talks, go to a professional together again if needed. It doesn’t sound like you want out of the marriage but would like to heal more. That’s a worthwhile endeavor. I hope when my husband has these feelings that he will bring them to me and we will work through them together. And if he can’t work through them then I will make every effort to help him go in without me. Because what I learned through it all is what it truly means to love someone and that is you hold their happiness equal to your own. I don’t want him to stay and be miserable, I want him to stay because he wants to. I love him more than anyone else on earth (well maybe outside of our kids but my kids are grown and off living their lives)
Don’t bottle it up, I think that makes it worse. Let us know how that goes.
