I don't have a lot of time but wanted to comment on this thread.
Welcome to the hell of infidelity. There is no quick fix, i'm sorry, or praise the lord i'm healed moment that will make this go away. The only way out of infidelity is through it.
I too had set a mantra of "I can't make any big choices of D while angry". This is a sham excuse to set an arbitrary date on a calendar and watch the days tick off. Until you start focusing on you and she starts focusing on her and both stop using the divorce as a fix you will struggle through this and prolong. Yes, you can't just divorce yourself away from the damage your WW did, because you will only take the hurt, pain, mistrust, etc. with you.
You will find your WW has always had issues with her self worth, self esteem, self image, and used very poor coping mechanisms to deal with these issues. Like compartmentalization, justification, minimization, and manipulation of self and others to feed the empty bucket she carried. She will find that no matter how she filled that bucket with those coping mechanisms it always felt light and empty because she couldn't just be happy with herself. This wasn't an accident there was many many poor choices before the first act of sex that she betrayed herself and you. The other man is just as broken as her. He used her comments, jokes, advances, and what ever else to fill his empty bucket. He was and is not unique just willing. He is scum, can't compare to you. You are the prize here.
So he used his access to her to boost her ego, make her feel special, made her feel sexy, made her valuable. All in a bubble relationship devoid of reality of life and all that goes with it, sickness, piss poor moods, toilet seat up, toothpaste squeezed from the top, all these things didn't exist inside this "feel good fantasy land". And these actors became each other's drug dealer. Only interacting when they could be cleaver or fill a void of time they were bored in etc. Pretty soon this drug/fantasy was more fun to be in than the mundane aspects of real life.
You can leave or stay at any time. I'm sure just like any other betrayed spouse we all loved our spouses before finding out. I tend to think you are leaning to R at this point but are using D as a hammer. There is no real punishment to fit this crime. A few key things need to happen for R to be even on the table as an option. Other than that you can choose to stay or go at any time just as she can!
1. Absolute NC, no exceptions, no last words, nothing nada. You should avoid talking to the other betrayed, other than facts. The other betrayed spouse doesn't have you or your wife's best interest in mind and is only a distraction from the real work. Immediate notification of any breach by the AP to you.
2. Complete honesty, open to all questions, and accountability. Trust is built over time. A timeline of events must be meet to your satisfaction.
These are just the primers. There are some great books to help you and her.
1. Not just friends by Doctor Glass
2. Rene Brown has some great self help books. Gift of imperfections is one that helps.
