Tall, dark, handsome, funny, kind, great with kids, six-figure salary, a harsh but fair critic of my creative output . the list of things people want from their spouses and partners has grown substantially in recent decades. So argues Eli Finkel, a professor of social psychology at Northwestern University in his new book, The All-or-Nothing Marriage.

As Finkel explains, it’s no longer enough for a modern marriage to simply provide a second pair of strong hands to help tend the homestead, or even just a nice-enough person who happens to be from the same neighborhood. Instead, people are increasingly seeking self-actualization within their marriages, expecting their partner to be all things to them. Unfortunately, that only seems to work if you’re an Olympic swimmer whose own husband is her brusque coach. Other couples might find that career-oriented criticism isn’t the best thing to hear from the father of your 4-year-old. Or, conversely, a violinist might simply have a hard time finding a skilled conductor-who also loves dogs and long walks on the beach-on Tinder.

I recently spoke with Finkel about how to balance this blend of expectations and challenges in a modern relationship. A lightly edited and condensed version of our conversation follows.

Eli Finkel: The main change has been that we’ve added, on top of the expectation that we’re going to love and cherish our spouse, the expectation that our spouse will help us grow, help us become a better version of ourselves, a more authentic version of ourselves.

Love in the Time of Individualism

Khazan: As in our spouse should, just to give a random example, provide interesting feedback on our articles that we’re writing?

Finkel: That’s obviously a white-collar variation on the theme, but I think up and down the socioeconomic hierarchy, it isn’t totally crazy these days to hear somebody say something like, “He’s a wonderful man and a loving father and I like and respect him, but I feel really stagnant in the relationship. I feel like I’m not growing and I’m not willing to stay in a marriage where I feel stagnant for the next 30 years.”

Masters of Love

Khazan: Why has that become something that we are just now concerned with? Why weren’t our great-grandparents concerned with that?

Finkel: The primary reason for this is cultural. In the 1960s, starting around that time, we rebelled as a society against the strict social rules of the 1950s. The idea that women were supposed to be nurturing but not particularly assertive. Men were supposed to be assertive but not particularly nurturing. There were relatively well-defined expectations for how people should behave, and in the 1960s, our society said, “To hell with that.”

Humanistic psychology got big. So these were ideas about human potential and the idea that we might strive to live a more authentic, true-to-the-self sort of life. Those ideas really emerged in the 1930s and 1940s, but they got big in the 1960s.

Khazan: You write about how this has actually been harder on lower-income Americans. Can you talk a little bit about why that is?

Finkel: People with college degrees are marrying more, their marriages are more satisfying, and they’re less likely to divorce. The debate surrounds [the question]: Why is it that people who have relatively little education and don’t earn very much money have marriages that, on average, are struggling more than those of us who have more education and more money?

There basically is no meaningful difference between the poorest members of our society and Malasia mujeres para la cita the wealthier members of our society in the instincts for what makes for a good marriage.
