6 Keys to a Healthy Marriage

If you locked it down this year, you have lots of company: More than 2 million men give up bachelorhood annually in the United States, usually between March and November. While the honeymoon effect can linger for months, every couple, newlywed or not, should do periodic marriage maintenance, says psychiatrist Scott Haltzman, M.D., author of The Secrets of Happily Married Men. That way, minor annoyances now won't blow up into big problems down the road. So whether you're recently hitched or have been tethered 10 years, watch for these roadblocks on the highway to happily ever after.

3 Weeks
Negotiate the Nest

THE SNAG: Women tend to prioritize the overall aesthetic of the home rather than picking specific areas, says Dr. Haltzman. She may even try to use the decor as a way to define the home as her domain.

YOUR PLAY: Look for ways to express yourselves individually—say, by each choosing a room to make your own, suggests Sam Gosling, Ph.D., author of Snoop: What Your Stuff Says About You.

8 Weeks
Deal with Debt

THE SNAG: Debt is a drag—more so if you both carry that baggage. And arguments over money tend to be intense, according to a study in Family Relations. So create a payoff plan—together.

YOUR PLAY: Set off a snowball effect: Pay the smallest debt first, says Dave Ramsey, author of The Total Money Makeover. Then roll your extra cash into the next-largest one, and so on.

3 Months
Respect Her Folks

THE SNAG: The in-laws may hover, but be nice: In a University of Michigan study, men who were close with their wives' parents early in marriage were less likely to wind up divorced after 16 years.

YOUR PLAY: Look for their talents. Is her dad a gifted griller? Her mom a tax whiz? Tap that expertise—they'll feel involved and stay out of your hair in other areas, says Dr. Haltzman.

7 Months
Stir Up the Sex

THE SNAG: Her libido may wane, says Dr. Haltzman. Typically it's nothing to worry about, but beware: Unfair distribution of chores might be to blame, a study in the American Sociological Review suggests.

YOUR PLAY: Mix it up. Pretend you're single and hit on each other at a bar. "It creates a sense of mystery, challenge, and uncertainty that some couples start to miss," Dr. Haltzman says.

10 Months
Break Routine

THE SNAG: Work. Dinner. Netflix. Sound familiar? Maybe it's time to shake things up. "Couples need to cultivate a spirit of curiosity," says Paul Hokemeyer, Ph.D., a relationship therapist in New York City.
