Hi fightin. The only other thing I can say is that, at the very least, you should tell your W that you're not interested in hearing about the OW. How would she feel if the situation were reversed?
I honestly don't know what I would do if my wife decided to keep the affair going after it was discovered, let alone discussing it with me, and I look to some of the vets on this board to give some advice because mine would probably be wrong.
As for guitar lessions... go for it! I can help if you want. I've been playing for about 30 years now
