Don't marry unless you're ready to pay
I mean "pay" literally: "How Did Johnny Depp Find Himself in a Financial Crisis?" includes this gem: "Depp’s fiery, 15-month marriage to the actress Amber Heard cost him another $7 million."
Depp got literally nothing out of that marriage apart from sex and some bad PR when she accused him of domestic violence. There is no reason for a man to marry today. Marriage is only a transfer of financial and attention assets from a man to a woman, as well as lawyers and whoever else can grab a piece of the action.
You probably won't lose $7 million, but you may lose a lot more proportionally speaking. These stories should remind you that marriage is a loser for men.
