lol. if marriage is just a piece of paper, why is it so hard and so scared to give one and take it THAT seriously
tho it's only a paper, but it is only a paper that can only give to one woman (even many muslim women nowadays will not accept polygamy)
and it's not just a paper, it protects the right of both party
I hope the billionaire wife has a pre-nup with this guy, if not he can claim half her $ if divorce, and especially their marriage is taken place in US.

its a piece of paper that is taken seriously by both parties, if the men is on the economical strong side, he will be more cautious, vice versa
nowadays its not always the men's lost
like this case, his wife probably forgive him because she overlooked prenuptial
