Sitting in car line so I only have a few moments......
She fired you as her husband. You DON'T get to control who she is around. Snooping to see if affair is still in progress to make sure she isn't "gaslighting" you is one thing but what you are doing is snooping to be controlling.
Honestly, I would have had the same reaction your wife did to the snooping. You DON'T have any right to control who she talks to, hangs out with, spends money on.
Have you thought about an IC? You have some major control issues to work on.
