It was too late to add it to my post, but a crucial part of our progress has been how DB and DR, and especially the posts here on 180s, helped me find out what I needed to change about myself. It has been a journey of self-improvements just as much as a relationship rescue. And I like myself a lot better these days!
I just re-read your posts to see if I could find out when you first found out about OW and how long the A has been going on, how they met and when it turned in to a PA.
I realized you have been together since you were both 15! I guess your H is wondering about what he has missed out on... Maybe you should read about midlife crisis and see if you think it fits?
