Frank and Gina* were the couple friends admired most—intellectual, funny, professors who taught on the same campus. They seemed perfectly matched. But after the birth of their first child, their sex life dropped out, they bickered incessantly, and both started taking antidepressants. Twenty years later, they're still married, with thriving careers and successful children, but privately they have been unhappy for a long time. "I used to feel that I was the light of her life, and now I feel as though she's annoyed that I'm still here," says Frank, who perpetually contemplates separating.

Close to half of today's marriages end in divorce, but that doesn't mean that couples who stay together are happy. "Even those marriages that remain intact have generally become less satisfying," says Eli Finkel, a professor of social psychology at Northwestern University.

Many couples carry on dutifully with the task of raising a family, showing a brave face to the world while secretly stuck in a mild but chronic depressive state I call "depressively married." Modern marriage, I believe, has hit a perfect storm—a collision between our biology and our contemporary values regarding marriage and child-raising.

Most unhappy marriages seem to founder on the same rocks: children. Noted marital researchers John and Julie Gottman, cofounders of the Gottman Institute in Seattle, conducted a long-term study of 130 newlywed couples. "The data shocked us," John says. Two-thirds of the new parents self-reported that they were "very unhappy after the birth of their first child."

When the Gottmans taped couples interacting in the lab, couples with children treated one another with more contempt, belligerence, and sadness, as well as with less affection, humor, and empathy than did couples without children but married for the same amount of time. Using a self-report measure of marital adjustment, they found that over the next year, hostility between partners increased dramatically, while the romance dissolved. Three years later, there was little improvement.

More than a hundred studies show that marital satisfaction falls off a cliff after the birth of the first child and doesn't get much better until the last child leaves for college.

Couples have been having children since the beginning of time; why have they become such relationship-killers only now? According to Stephanie Coontz, author of Marriage, a History and professor of history at Evergreen State University, until the 19th century, marriage served the purposes of reproduction, economic security, and the creation of alliances between families. No one would have dreamed of resting such a cornerstone of society on something as fickle as love. There was little room for feelings of disappointment.

By the 1950s, people married predominantly for love, although divorce was still rare. In the Leave It to Beaver marriage, men and women had separate roles, separate sets of friends, and separate leisure activities. Children were told to go out and play (and no one felt guilty about it). As long as women performed their "marital duty" (whether they enjoyed it or not), sexual adjustment in marriage was deemed good enough. And if either partner had an affair, it seemed easier to keep the fact secret than threaten the relationship.

In the 1970s, with the sexual revolution and the birth of modern feminism, marriage underwent a second transformation: Simultaneously, the bar of our expectations was raised while the resources we gave to our relationships were diminished.

In the contemporary era, couples expect to be best friends, to have complete equality in all spheres of life, and to sustain an ongoing romance with mutual sexual satisfaction—and an exclusive relationship at that.

At the same time, modern marriage is accompanied by ever more dedication of time and resources to children.

These are Olympian expectations, but you'd have a better chance of winning the actual Olympics. The new marital ideal is, observes Coontz, "like the little girl with the curl; when it works, it's really, really good. And when it doesn't, we feel deeply betrayed."

Orgasms for All

By the 1970s, Americans had discovered the female orgasm, and sex became an equal opportunity enterprise. While the shift has expanded human potential and produced richer sex lives for men and women, it has also made postbaby adjustment a more shocking disappointment and a recipe for depressive marriage. Sexual satisfaction is one of the best predictors of overall happiness. Yet in one study, only 12 percent of couples reported not having "serious sexual problems" after having children.

It's no one's fault. The abrupt change in sexual connection between partners is hormonally influenced. Throughout the nursing years, prolactin production depresses the sex hormones estrogen and testosterone, biologically encouraging women to de-emphasize mating and focus energy on keeping their newborn alive. Further, as breastfeeding stimulates the bonding hormone oxytocin, it prompts a shift in attention toward baby and away from husband.

A sexual chasm opens between partners that wasn't there before. The Gottmans found that a full three years after childbirth, women report feeling "not very sexual" and want sex no more than "every week or every other week," while men report feeling "extremely sexual," wanting sex "every day." And when couples do have sex, there is a great discrepancy in their enjoyment of it. Men have orgasms six times more often than their partners.

Many men suddenly feel undesired and unloved. "Something inside them just breaks," says Julie Gottman. The dramatic switch in women's attention from mate to baby, guided by oxytocin, may be "evolution at its best, but it is detrimental to intimacy between the partners." What's good for reproductive success is bad for 21st-century marital success.
