If you're a girl, it's extremely easy to get your revenge in the form of sex. Sign up to tinder and you'll get dozens of matches per day, so you could have sex as many times as you want, for free, while he has to pay for it. You'll bury him, he'll cry after he finds out how many men have used you. And send him pics too. There's no way he can win at this game. To test this theory, I once created a fake tinder account using a picture of a very unattractive girl and I received literally dozens of matches per day, dozens of men wanted to have sex with the fake profile that I created using the picture of a girl who's like 2/10. It really works. So if you're serious about revenge and you want to make him cry, go out and have sex with as many men as possible.
