AITA for wanting a divorce?

Back story: 2 years ago I (M35) found some snapchats on my wifes (F 34) phone (not snooping, our daughter was playing games on it when they popped up) of her and some of her "guy friends " talking. One chat was her talking about her ex from 10 yrs ago, how he was amazing, had a nice ass, etc. So i got curious and then scooped through her texts, and found deletes text of her and a different guy, where he was asking to see her tits, wanted to take her to a wedding, etc. She didnt send any pics, but she didnt shut him down either. I confronted her about it and asked who so and so was, and she tried to say I have no idea, until I pulled her phone and showed her the deleted texts. I left that night, and almost divorced her but decided to give her a chance.

Recently: she didnt know that i had her login info for her Instagram (only social media she has now) and some guy she's never mentioned started following her. He sent her a message with a tiktok video that had a guy flexing his forearms popping his veins, then it panned to a nurse who was obviously getting turned on by it. A few days later he sent her a message, but that same day she realized I was on her IG and deleted the message before I could see it.

Just not sure what to do here.
