What is the best revenge to get on a cheater?

I got cheated on by my boyfriend. I want him to pay since he has absolutely no conscience and continues to play mind games with me and other girls. Don't tell me to go on with my life or flaunt another dude in front of him because I really want to make him suffer for what he did to me and his family. If you have been in my shoes, what did you do? What should I do?
