I have seen many wealthy men whose marriages failed. Is it that they don't know how to use the money on their wives or what?
It's because the wealthy men demand something that the wives can't accept.
It's mostly about sex, if the wealthy men demand to having sex with many women and their wives can't accept it, that's why the marriages failed.
Have you ever heard Dubai Porta Potty? if the wealthy men have disgusting kink like asking their wives to eat and swallow their poop, if the wives can't accept it, the marriages failed.
So, things other than money, which could be more difficult than money to get will arise. Mate, have you forgotten that women are dynamic and very much insatiable? Money doesn't solve everything
What's that? say it.
