How would you exact revenge on a partner that you found has been cheating on you throughout the relationship?

Moving on and being happy, not letting their betrayal effect my future relationships and not allowing myself to be poisoned by holding onto negativity internally over someone who doesn't matter.

By simply breaking up with them and moving on. It sounds simple but it has a huge impact on their ego if they see you can easily move on from them. It makes them seem powerless.

Upload any nude pictures you have have of him/her on Facebook or your social media of choice, include a description making it very clear that your partner cheats on people, and make sure his/her family and friends know about it.

Leave them? Leaving the person is the sweetest revenge because they will end up wanting you back. If you stay with a cheater, you're a coward.
