How Friendships Change in Adulthood

In the hierarchy of relationships, friendships are at the bottom. Romantic partners, parents, children—all these come first.

This is true in life, and in science, where relationship research tends to focus on couples and families. When Emily Langan, an associate communication professor at Wheaton College, goes to conferences for the International Association of Relationship Researchers, she says, “friendship is the smallest cluster there. Sometimes it’s a panel, if that.”

Friendships are unique relationships because unlike family relationships, we choose to enter into them. And unlike other voluntary bonds, such as marriages and romantic relationships, they lack a formal structure. You wouldn’t go months without speaking with or seeing your significant other (hopefully), but you might go that long without contacting a friend.

Still, survey upon survey upon survey shows how important people’s friends are to their happiness. And though friendships tend to change as people age, there is some consistency in what people want from them.

“I’ve listened to someone as young as 14 and someone as old as 100 talk about their close friends, and [there are] three expectations of a close friend that I hear people describing and valuing across the entire life course,” says William Rawlins, the Stocker Professor of Interpersonal Communication at Ohio University. “Somebody to talk to, someone to depend on, and someone to enjoy. These expectations remain the same, but the circumstances under which they’re accomplished change.”

The voluntary nature of friendship makes it subject to life’s whims in a way that more formal relationships aren’t. In adulthood, as people grow up and go away, friendships are the relationships most likely to take a hit. You’re stuck with your family, and you’ll prioritize your spouse. But where once you could run over to Jonny’s house at a moment’s notice and see if he could come out to play, now you have to ask Jonny if he has a couple hours to get a drink in two weeks.

The beautiful, special thing about friendship, that friends are friends because they want to be, that they choose each other, is “a double agent,” Langan says, “because I can choose to get in, and I can choose to get out.”

Throughout life, from grade school to the retirement home, friendship continues to confer health benefits, both mental and physical. But as life accelerates, people’s priorities and responsibilities shift, and friendships are affected, for better, or often, sadly, for worse.

The saga of adult friendship starts off well enough. “I think young adulthood is the golden age for forming friendships,” Rawlins says. “Especially for people who have the privilege and the blessing of being able to go to college.”

During young adulthood, friendships become more complex and meaningful. In childhood, friends are mostly other kids who are fun to play with; in adolescence, there’s a lot more self-disclosure and support between friends, but adolescents are still discovering their identity, and learning what it means to be intimate. Their friendships help them do that.

But “in adolescence, people have a really tractable self,” Rawlins says. “They’ll change.” How many band T-shirts from Hot Topic end up sadly crumpled at the bottom of dresser drawers because the owners’ friends said the band was lame? The world may never know. By young adulthood, people are usually a little more secure in themselves, more likely to seek out friends who share their values on the important things, and let the little things be.

To go along with their newly sophisticated approach to friendship, young adults also have time to devote to their friends. According to the Encyclopedia of Human Relationships, many young adults spend 10 to 25 hours a week with friends, and the 2014 American Time Use Survey found that people aged 20 to 24 spent the most time per day socializing on average of any age group.

College is an environment that facilitates this, with keggers and close quarters, but even young adults who don’t go to college are less likely to have some of the responsibilities that can take away from time with friends, such as marriage, or caring for children or older parents.

Friendship networks are naturally denser, too, in youth, when most of the people you meet go to your school or live in your town. As people move for school, work, and family, networks spread out. Moving out of town for college gives some people their first taste of this distancing. In a longitudinal study that followed pairs of best friends over 19 years, a team led by Andrew Ledbetter, an associate communications-studies professor at Texas Christian University, found that participants had moved an average of 5.8 times during that period.

“I think that’s just kind of a part of life in the very mobile and high-level transportation- and communication-technology society that we have,” Ledbetter says. “We don’t think about how that’s damaging the social fabric of our lives.”

We aren’t obligated to our friends the way we are to our romantic partners, our jobs, and our families. We’ll be sad to go, but go we will. This is one of the inherent tensions of friendships, which Rawlins calls “the freedom to be independent and the freedom to be dependent.”

“Where are you situated?” Rawlins asks me, in the course of explaining this tension. “Washington, D.C.,” I tell him.

“Where’d you go to college?”

“Chicago.”

“Okay, so you’re in Chicago, and you have close friends there. You say ‘Ah, I’ve got this great opportunity in Washington …’ and [your friend] goes, ‘Julie, you gotta take that!’ [She’s] essentially saying, ‘You’re free to go. Go there, do that, but if you need me, I’ll be here for you.’”

I wish he wouldn’t use me as an example. It makes me sad.

As people enter middle age, they tend to have more demands on their time, many of them more pressing than friendship. After all, it’s easier to put off catching up with a friend than it is to skip your kid’s play or an important business trip. The ideal of people’s expectations for friendship is always in tension with the reality of their lives, Rawlins says.

“The real bittersweet aspect is young adulthood begins with all this time for friendship, and friendship just having this exuberant, profound importance for figuring out who you are and what’s next,” Rawlins says. “And you find at the end of young adulthood, now you don’t have time for the very people who helped you make all these decisions.”

The time is poured, largely, into jobs and families. Not everyone gets married or has kids, of course, but even those who stay single are likely to see their friendships affected by others’ couplings. “The largest drop-off in friends in the life course occurs when people get married,” Rawlins says. “And that’s kind of ironic, because at the [wedding], people invite both of their sets of friends, so it’s kind of this last wonderful and dramatic gathering of both people’s friends, but then it drops off.”

In a set of interviews he did in 1994 with middle-aged Americans about their friendships, Rawlins wrote that “an almost tangible irony permeated these [adults’] discussions of close or ‘real’ friendship.” They defined friendship as “being there” for each other, but reported that they rarely had time to spend with their most valued friends, whether because of circumstances, or the age-old problem of good intentions and bad follow-through: “Friends who lived within striking distance of each other found that … scheduling opportunities to spend or share some time together was essential,” Rawlins writes. “Several mentioned, however, that these occasions often were talked about more than they were accomplished.”

As they move through life, people make and keep friends in different ways. Some are independent, make friends wherever they go, and may have more friendly acquaintances than deep friendships. Others are discerning, meaning they have a few best friends they stay close with over the years, but the deep investment means that the loss of one of those friends would be devastating. The most flexible are the acquisitive—people who stay in touch with old friends, but continue to make new ones as they move through the world.

Rawlins says that any new friends people might make in middle age are likely to be grafted onto other kinds of relationships—as with co-workers, or parents of their children’s friends—because it’s easier for time-strapped adults to make friends when they already have an excuse to spend time together. As a result, the “making friends” skill can atrophy. “[In a study we did,] we asked people to tell us the story of the last person they became friends with, how they transitioned from acquaintance to friend,” Langan says. “It was interesting that people kind of struggled.”

But if you plot busyness across the life course, it makes a parabola. The tasks that take up our time taper in old age. Once people retire and their kids have grown up, there seems to be more time for the shared-living kind of friendship again. People tend to reconnect with old friends whom they’ve lost touch with. And it seems more urgent to spend time with them—according to socio-emotional selectivity theory, toward the end of life, people begin prioritizing experiences that will make them happiest in the moment, including spending time with close friends and family.

And some people do manage to stay friends for life, or at least for a sizable chunk of life. But what predicts who will last through the maelstrom of middle age and be there for the silver age of friendship?

Whether people hold onto their old friends or grow apart seems to come down to dedication and communication. In Ledbetter’s longitudinal study of best friends, the number of months that friends reported being close in 1983 predicted whether they were still close in 2002, suggesting that the more you’ve invested in a friendship already, the more likely you are to keep it going. Other research has found that people need to feel like they are getting as much out of the friendship as they are putting in, and that that equity can predict a friendship’s continued success.

Hanging out with a set of lifelong best friends can be annoying, because the years of inside jokes and references often make their communication unintelligible to outsiders. But this sort of shared language is part of what makes friendships last. In the longitudinal study, the researchers were also able to predict friends’ future closeness by how well they performed on a word-guessing game in 1983. (The game was similar to Taboo, in that one partner gave clues about a word without actually saying it, while the other guessed.)

“Such communication skill and mutual understanding may help friends successfully transition through life changes that threaten friendship stability,” the study reads. Friends don’t necessarily need to communicate often, or intricately, just similarly.

Of course, people can communicate with friends in more ways than ever, and media multiplexity theory suggests that the more platforms through which friends communicate—texting and emailing, sending each other funny Snapchats and links on Facebook, and seeing each other in person—the stronger their friendship is. “If we only have the Facebook tie, that’s probably a friendship that’s in greater jeopardy of not surviving into the future,” Ledbetter says.

Though you would think we would all know better by now than to draw a hard line between online relationships and “real” relationships, Langan says her students still use “real” to mean “in-person.”

There are four main levels of maintaining a relationship, and digital communication works better for some than for others. The first is just keeping a relationship alive at all, just to keep it in existence. Saying “Happy birthday” on Facebook, liking a friend’s tweet—these are the life-support machines of friendship. They keep it breathing, but mechanically.

Next is keeping a relationship at a stable level of closeness. “I think you can do that online too,” Langan says. “Because the platforms are broad enough in terms of being able to write a message, being able to send some support comments if necessary.” It’s sometimes possible to repair a relationship online too (another maintenance level), depending on how badly it was broken—getting back in touch with someone, or sending a heartfelt apology email.

“But then when you get to the next level, which is: Can I make it a satisfying relationship? That’s I think where the line starts to break down,” Langan says. “Because what happens often is people think of satisfying relationships as being more than an online presence.”

Social media makes it possible to maintain more friendships, but more shallowly. And it can also keep relationships on life support that would (and maybe should) otherwise have died out.

“The fact that Tommy, who I knew when I was 5, is still on my Facebook feed is bizarre to me,” Langan says. “I don’t have any connection to Tommy’s current life, and going back 25 years ago, I wouldn’t. Tommy would be a memory to me. Like, I seriously have not seen Tommy in 35 years. Why would I care that Tommy’s son just got accepted to Notre Dame? Yay for him! He’s relatively a stranger to me. But in the current era of mediated relationships, those relationships never have to time out.”

By middle age, people have likely accumulated many friends from different jobs, different cities, and different activities, who don’t know one another at all. These friendships fall into three categories: active, dormant, and commemorative. Friendships are active if you are in touch regularly; you could call on them for emotional support and it wouldn’t be weird; if you pretty much know what’s going on with their lives at this moment. A dormant friendship has history; maybe you haven’t spoken in a while, but you still think of that person as a friend. You’d be happy to hear from them, and if you were in their city, you’d definitely meet up.

A commemorative friend is not someone you expect to hear from, or see, maybe ever again. But they were important to you at an earlier time in your life, and you think of them fondly for that reason, and still consider them a friend.

Facebook makes things weird by keeping these friends continually in your peripheral vision. It violates what I’ll call the camp-friend rule of commemorative friendships: No matter how close you were with your best friend from summer camp, it is always awkward to try to stay in touch when school starts again. Because your camp self is not your school self, and it dilutes the magic of the memory a little to try to attempt a pale imitation of what you had.

The same goes for friends you see only online. If you never see your friends in person, you’re not really sharing experiences so much as just keeping each other updated on your separate lives. It becomes a relationship based on storytelling rather than shared living—not bad, just not the same.

“This is one thing I really want to tell you,” Rawlins says. “Friendships are always susceptible to circumstances. If you think of all the things we have to do—we have to work, we have to take care of our kids, or our parents—friends choose to do things for each other, so we can put them off. They fall through the cracks.

After young adulthood, he says, the reasons that friends stop being friends are usually circumstantial—due to things outside of the relationship itself. One of the findings from Langan’s “friendship rules” study was that “adults feel the need to be more polite in their friendships,” she says. “We don’t feel like, in adulthood, we can demand very much of our friends. It’s unfair; they’ve got other stuff going on. So we stop expecting as much, which to me is kind of a sad thing, that we walk away from that.” For the sake of being polite.

But the things that make friendship fragile also make it flexible. Rawlins’s interviewees tended to think of their friendships as continuous, even if they went through long periods in which they were out of touch. This is a fairly sunny view—you wouldn’t assume you were still on good terms with your parents if you hadn’t heard from them in months. But the default assumption with friends is that you’re still friends.

“That is how friendships continue, because people are living up to each other’s expectations. And if we have relaxed expectations for each other, or we’ve even suspended expectations, there’s a sense in which we realize that,” Rawlins says. “A summer when you’re 10, three months is one-thirtieth of your life. When you’re 30, what is it? It feels like the blink of an eye.”

Perhaps friends are more willing to forgive long lapses in communication because they’re feeling life’s velocity acutely too. It’s sad, sure, that we stop relying on our friends as much when we grow up, but it allows for a different kind of relationship, based on a mutual understanding of each other’s human limitations. It’s not ideal, but it’s real, as Rawlins might say. Friendship is a relationship with no strings attached except the ones you choose to tie, one that’s just about being there, as best as you can.
