How would you…?!?

If you found out your special someone, not necessarily a spouse, was cheating..what would you do to get revenge without doing something that will a) get you into trouble and b) cause harm to others?

I was thinking along the lines of maybe showing them what they lost and what they are going to miss out on, but I don’t know which is why I am asking all of you!

I welcome your ideas! Thanks in advance!
You walk into a club with your best friend, just a night to have fun to yourselves. You are there a while when you notice your fiance all over a girl, his hand roaming her body. He told you he was going out with some guys, but it is just him and this mystery girl.

What would you do? How would you bring this up?
