Cheating stories written in first person

Kind of an odd request, but I am looking for books about infidelity that read like posts you would find on subreddits like r/survivinginfidelity and r/relationship_advice. I love a good cheating story, and I always find myself lurking on subs just like those ones. But I am looking to be more productive with my time, while trying to minimize my screentime as much as possible!

Specifically, I am in search for a book written in first person about someone finding out about their partner cheating on them in great detail and every step they took to get their sweet revenge!

I want to preface that I am looking for a book that's written in more of a survivors perspective rather than a book glorifying/romanticizing the cheating. The more more insane and unbelievable it sounds, the better! Bonus points if it's based on a true story, but it does not have to be.

Thanks! 😀
