I strongly suggest you do not change her financial situation by selling the business. If you ultimately end up divorcing and she technically has no more income you could end up in a very bad financial situation for a long time. A judge may order you to pay alimony, you will definitely be paying child support if the kids are under 18.
It took my wife a while just to use the word affair. She would refer to it as the incident. While talking with my IC one day I mentioned this and she stopped me. She said until your wife can take full accountability for the affair and use the word AFFAIR, reconciliation will be very hard.
So the next time my wife and I were talking and she used the word incident I said something to the effect of how are we going to try and fix this relationship if you can't even say the word affair?
Imo, she didn't want to use that word because that would make her an adulterous. Now it was obvious she was but she struggled to accept it. Hell I think it was a few months before she finally accepted full responsibility and could honestly answer the question "what did you think would happen if I found out?"
Her response had been I never thought about it but after a few months she finally admitted "I figured you would be upset for a few days and then get over it." Obviously at this point she had little to zero respect for my feelings and the potential Fallout. She was having way too much fun
In the beginning I was the one reading and researching everything I could and my wife was content to just let me until I finally told her you need to be the one doing this. You need to be the one trying to figure out how to fix this. And I learned this after finding this forum
My advice is that you do the 180 and just walk away. Make some appointments with divorce attorneys just to see where you stand and let your wife know you're doing it. Tell her you are not actively filing for divorce but you want to know where you stand should she not put in the effort to repair the damage she caused
The WS has to grasp the reality that their actions may very well have destroyed the relationship and divorce is the outcome ESPECIALLY if he/she doesn't put in a buttload of effort
All of us understand that your brain is going a mile a minute and that is totally understandable and to be expected. It's hard to implement some of the advice given here. For me I was scared to death that she had no problem just saying okay, we're done, let's get the divorce over with so I can move on. It took me a long time to get my proverbial balls back but once I did that's when Real Change started to happen
Keep posting if you feel it's helping. For me the more I talked about it the better I felt, but that's me
