Yet commitment and marriage offer real physical and financial rewards. Touting the benefits of marriage may sound like conservative policy rhetoric, but nonpartisan sociological research backs it up: Committed partners have it all over singles, at least on average. Married people are more financially stable, according to Linda Waite, a sociologist at the University of Chicago and a coauthor of The Case for Marriage: Why Married People are Happier, Healthier and Better Off. Both married men and married women have more assets on average than singles; for women, the differential is huge.

The benefits go beyond the piggy bank. Married people, particularly men, tend to live longer than people who aren’t married. Couples also live better: When people expect to stay together, says Waite, they pool their resources, increasing their individual standard of living. They also pool their expertise—in cooking, say, or financial management. In general, women improve men’s health by putting a stop to stupid bachelor tricks and bugging their husbands to exercise and eat their vegetables. Plus, people who aren’t comparing their partners to someone else in bed have less trouble performing and are more emotionally satisfied with sex. The relationship doesn’t have to be wonderful for life to get better, says Waite: The statistics hold true for mediocre marriages as well as for passionate ones.

A committed relationship allows you to drop pretenses and seductions, expose your weaknesses, be yourself—and know that you will be loved, warts and all.

Promoting co-dependence.
