Am in my 30’s, My wife and I have been living in separate locations about 4yrs now. With intermittent visits 3-4months intervals.
Few days back wen she visited, I exchanged one of my new fones with her so while I was checking out the fone so I could delete some stuff and familiarize with the fone(her previous fone ,now mine)I casually stumbled into her FB & WhatsApp and saw sex chats with different men including her ex. This will be first ever I would be checking her SM, calls, SMS or whatsoever.
When I confronted her with these evidences, she rather than apologize to me, began guilt tripping me with how she’s been ignoring my own philandering (but no evidence, she’s just basing them on speculations).
She dragged the fone in a bid to snatch it from me at the Mall in public.
I told her point blank how disappointed & angry I am and am separating from her.
I arranged for for logistics to take her to our house in the town she stays.
She’s called my dad. I have no idea what she’s told them, but I got evidences.
We do not yet have a child together.

Did I overreact??
How do I deal with this situation
Mature advices will be appreciated from experienced people
