Money advice for a lasting marriage

Create a shared budget

You never gave much thought to splurges like pedicures or tickets to sporting events when you were single, but those expenses take on new meaning in a marriage.

Matt Bell, author of Money and Marriage: A Complete Guide for Engaged and Newly Married Couples, says spending you took for granted while you were single needs to be renegotiated after marriage.

"You have to talk about your priorities for saving and spending, to be on the same page, and if there are differences, you need to talk through them," Bell says.

Financial vow: Track expenses together. Once you have the numbers, create a budget that reflects your priorities as a couple. Bell advises couples to plan for living expenses and investments as well as splurges like romantic dinners and vacations.

"Look at all financial decisions in terms of what is best for the marriage," Bell advises. "Your attitude should be, 'We’re going to set goals together.' "
