For the past 10 years, the world of finance has found its way into more aspects of our lives, from our homes and retirements to our milk and gas prices. It also crept into relationships and marriages.

Wealthy couples will almost always deny any wealth effect in their relationships. When the 30-year-old blonde says she married her 60-year-old husband for love (and not the $300,000-a-year "personal budget") you know there likely is more to the story. Even longtime couples I met for "Richistan" often had agreements and deals related to money, whether it involved post-nups to required funds for pet philanthropy projects. It's naive to believe money doesn't play a role in every relationship, even if that role is small.
