FMC gets publicly humiliated by her boyfriend/ex and then absolutely destroys him afterwards

Heyyy readers!! So I just watched a clip of Mika (Allie from Off Campus) with her ex-fiance on a podcast. He was asked to describe mika and he said some bitch and I was sitting there embarrassed and cringing for her. (And yes, maybe this sounds a little parasocial, but thank god they broke up 😭).

Now I'm looking for books where the FMC gets humiliated, disrespected, or publicly embarrassed by the OM (boyfriend, fiancé, ex, etc.) or even by someone else. Bonus points if the MMC witnesses it and either stands up for her, comforts her, or helps her get revenge.

I'm good with either:

- MMC defending her at the moment.

- MMC helping her plan/pay back the humiliation later.

But I need the FMC to have a backbone and clap back eventually. Maybe she dumps her cheating fiancé, exposes him, gets her revenge, or simply moves on and lives her life while he regrets everything.

Please give me some recommendations :)
