She should've start letting the mistress parents know that they've raised a homewrecker, slowly torment them, ruined her every new relationship, be it romantic or friendship and tell them that she loves to cheat. Traumatized her until she leaves the company and send emails to which every company she works at, of what kind of person that they choose to hire. Let everyone know that someone died because she can't stop herself seducing other man, do all of those while reminding the father of the sins that he committed and when u don't need his support start your revenge on him. Make him regret that he's a fucking asshole, until he wish that he's the one who died instead of his wife.
But of course, they say that forgiving and moving on is the best revenge. But I’m not that nice enough, if their karma is late then you should be their own karma HAHAHAHAHAHA *cough*
