Of course you are. Round one is the most exhilarating, and often uses the most energy.
Two things.
Stop using the word 'divorce' and the word 'leave' in the context of the relationship for now.
Secondly, my push for you to try is for many reasons, but most importantly for you, if you exit without a hard effort, you will have regrets. If you exit after a good effort, even with a bloody nose, you will feel like you tried your best. This is important for you later, and important for later potential relationships.
As much as is possible, don't use damaging words with your wife, no matter how angry you are. Be firm and somber, but kind. Don't yell.
Hang in there HairDog.

I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
