AIO for going nuclear over my soon ex-fiances cheating?

I [33m] was with my now ex fiance [32f] for 7 years. We shared a lot of common interests and had a great relationship overall which is why this honestly caught me off guard and really shook me. My ex had a larger friend pool that predominately coexistence and overlapped mine. She makes a lot of new friends so when she started to spend more time with this new guy I thought it was just a new friend added to the group.

Turns out this new friend was also someone she worked with. She had always talked about someone at work being creepy and into her but agter a night or two of talking about it she said nothing continued on rather then the guy being overly friendly so I figured she said im engaged and life moved on.

As time went on she had talked about a new friend that her and everyone else I knew started to hangout with named Jared. I didnt know until now that this guy was the creepy affectionate guy from work that she spoke of.

Time went on and some of our friends had told me they seemed like more of an item when together. I had only met the guy on two occasions after that he would only show up to whatever was going on that weekend when I wasn't there, naive of me but I trusted my ex.

Over time I had gotten a call as I was listed as a contact for my exs work, she had messed up with her time off and had apparebtly been calling out far more regularly. Her supervisor stated her condolences for my loss and to tell my e to fix her timesheet.

I was confused as no one I knew of died, my ex wasnt out of town. Some suspicion got over me. So I called friends to find her wearabouts. No friend knew where she was, the friend who stated her and Jared seemed like an item told me the truth after calling her saying "they left around 7am to go out for a day trip together."

This was around 11am, I didnt care to hear her side I called aome friends and moved her shit to the sidewalk. The friend said she only told me cause she felt bad I didn't know she was with the guy from work. Again confused I said she told me this guy from work was a creep. They had been a secret for a month or so.

I searched the staff directory found that Jared was the guy from work. Called her boss back to inform her lies and situation with Jared. All in all once she returned she was furious which turned to tears. I told her to give me my key and go stay with Jared or outside I honestly didnt care.

Weeks later I found out from her angrily calling me that its likely she'll be possibly fired for her lying, behavior, and office drama that she brought her boss into. Thats all pending but

Did I go to far just removing this all from my life and reporting her to her boss for lying about my family dying?

Tldr: fiance to be cheated, lied everyone knew but me. Reported her lies to her boss and now her and Jared maybe terminated.
