She cheated [MF]

I (26M) found out my wife (29F) is having an affair with an ex boyfriend of hers.

I had noticed lately that she seemed to be on her phone quite a bit lately and was always very protective about not leaving it out anywhere. A few weeks ago I woke up in the middle of the night and snuck off with her phone to see if I could dig anything up. I searched through her Snap and other social media, texts, emails and couldn’t find anything.

So I logged in to her old college email account that still for some reason is active. I looked all around and in the trash folder, there was an email that was asking for verification from only a few weeks prior. When I opened that trashed email it had listed a different email account and said her school email was listed as a backup account, was this correct?

So I took a mental note of what that email that was listed was, made sure I left her apps and websites exactly as she’d left them, and put everything back. I grabbed my phone and tried that email address.
