I don't mean to ignore what you wrote but I'm curious to know if you've read the book, after the affair. It gives you some insight on how to repair the damage caused and gives you insight as to what the betrayed spouse is feeling/thinking.
Consider it if you haven't already looked at it.
Many hugs to you.
