I 30M and 30F have been together for 16 years and just "celebrated" out 10 year marriage anniversary. Recently some old dirt got dug up and I confirmed my gf at the time (now wife) had sex with my cousin when I was living with him about 12 years ago. We have since pushed through even though I sniffed it out back them and she made me think he had just stolen pictures and stuff off my phone while I was sleeping and was texting people a "fantasy". Another incident happened about 9 years ago where she was snapchatting a guy from high school and it wasn't nsfw pictures but she needed attention I wasn't giving at the time. We pushed through that. Fast forward all these years, we have a house, I cook majority of dinners, wash most of the clothes, do a lot of the chores, 2 boys in travel baseball, and I coach both teams. I've been always dedicated to my family and have always made passes at my wife. We have had ups and downs about what each other's needs are and gotten through them. But something just ticked in my head until I took a deep dive into my wife's phone. And in the "recently deleted" portion of the text where 1500 messages to a 25M about baseball stuff, gym stuff, trying to find time for her to come "spend the night" and even a time this week where they met up and he made her food.Also she had told this guy about an incident that happend at a sports bar we were at, where a guy grabbed her around her waist and didnt even tell me. She insist it's just a mistake and that I'm the man she wants forever and always. I deeply love her but I've learned with a little talk and persistence, she can be persuaded. Is their a way to get passed this? AITA if I ask for a divorce?
