There are many reasons that married couples argue. Not surprisingly, the number one reason is money. Indeed, even when people have a strong, stable relationship - and regardless of how much money they have - money is still often a source of conflict. These arguments have detrimental results. Research from Utah State University finds that disagreements over money are the single best indicator of divorce.

So while there are many steps you can take to improve your marriage or keep it strong, one of the best is to figure out how to talk about money with your spouse. Unfortunately, doing so is not easy because discussing money makes people uncomfortable. After all, as we're growing up, most people learn not to talk about money instead of how to talk about it.
