Tell the wife, her husband hit on you, you have it on tape, and you'll put it all over social media unless she comes up with $200.
Then go to the husband and tell him, his wife was hitting on you but you didn't feel right about it so you turned her down and thought you should tell him.
When the wife confronts the husband about hitting on you, he'll blow that off and want to know why she's lying about wanting to sleep with you.
