Boys' Nights Can Save a Marriage or Sink It. Here's the Difference.

In pop culture, boys' nights have gotten a bad rap. We associate them with movies or memes that suggest they're chaotic to the point of immorality.

Yet the fact remains that male bonding is incredibly important. A recent study found that men who maintained friendships and were part of a strong social network had a greater sense of purpose in life. It recommended investing in long-term friendships and seeking out opportunities where men could connect with other men. Male friendships can also be a great buffer for stress, improving men's health and lifestyle habits.

A reason that we might not value male friendships as highly in our culture is because the way men and women spend time with their friends looks and feels very different. Psychologists even have names for it. Male friendship tends to be "side by side," and female friendship more "face to face," a distinction researcher Paul Wright drew back in 1982 that has held up ever since. Men bond shoulder to shoulder, aimed at some shared activity, whether that's watching the game or fixing something in the garage. The talking still happens, but it happens around the thing they're doing. Women bond by turning toward each other, and the talking is the point.

Boys' nights give men a release valve to fraternize the way only men can.

That's why a boys' night can look, from the outside, like it accomplished nothing. Your husband was gone four hours and came home knowing less about his best friend's messy breakup than you'd pick up from a stranger in a bathroom line. But Geoffrey Greif, a University of Maryland professor who interviewed hundreds of men for his research on male friendship, found that guys often bond by not putting each other on the spot. They tend to be "fixers" more than confessors, and a lot of their closeness runs on presence and inside jokes rather than heart-to-hearts. It's a lower-key kind of closeness, and it's easy to underestimate. Boys' nights give men a release valve to fraternize the way only men can. As sweet as your husband may be around you and your family, when he's with his male friends, he embodies a different side of his masculinity. They joke about things girls don't usually find funny or interesting. They might debate WWII history, their weightlifting regimens, or who stands the best chance of fighting off a bear in the wilderness. As strange as it might sound to us, male bonding often looks like wrestling, roughhousing, and arguing over sports.

When women hang out together, we're doing something more delicate, and the research backs the stereotype. A meta-analysis of 205 studies covering more than 23,000 people found that women self-disclose more than men, and the gap is widest of all between two women. Opening up is how female friendship gets built and kept up, which is why a single coffee date can double as a therapy session. There's a name for that instinct too. UCLA researchers called it "tend and befriend," the finding that women under stress are especially likely to reach for other women for comfort instead of squaring up or bolting, a response they tied to the hormone oxytocin.

So we bond over shopping, celebrity gossip, and venting about whatever's going on at home, and we're far more likely to spend an afternoon over brunch mimosas than arm-wrestling each other to exhaustion. His half of this works the same way ours does, just pointed at the activity instead of the conversation.

The association between male bonding and cheating may be more social stigma than actual phenomenon.

Despite these differences in how each of us bonds with our friends, in a marriage, each spouse deserves positive same-sex friendships. Unfortunately, there's a double standard here, one partially linked to the pop-culture perception of male friendships. Male friendships largely have a reputation for leading to sexual promiscuity. They're associated with going to bars, hitting on women, and blowing hundreds at strip clubs. This link between boys' nights and cheating gets perpetuated constantly by movies, television, and even music. And the data does show a gap, though a smaller one than the stereotype implies. The General Social Survey finds that about 20% of married men and 13% of married women admit to having had sex outside their marriage, and even that difference has been shrinking for decades, from roughly 15 points wide in the 1990s to closer to 7 today. Those numbers also rest on self-reporting, which may not be entirely accurate. And for all the cultural hand-wringing, no research has ever isolated a night out as a cause of cheating. Studies that track who actually strays keep pointing back to a person's own appetite for casual sex and how committed they are to the relationship, not to whether they spent Friday night out with friends. The association between male bonding and cheating, in other words, may be more social stigma than actual phenomenon.

There's also a real protective factor most people who are anti-boys' night ignore. Married men who are devout Christians—meaning they pray frequently and regularly attend church—are significantly less likely to cheat on their spouses. National data points the same direction: the same analysis of General Social Survey figures found that people who rarely or never attend religious services are among the most likely to have strayed. So if your husband is spending his time with other religious men, he's even less likely to be up to anything at all.

None of this means every boys' night is a good one, though. Dedicated nights out can be one of the healthiest things in a marriage or one of the most corrosive, and the difference lies in the details. Handled well, friendships outside your marriage can actually strengthen it, and there's science to back that up. One study found that when couples fight, the stress hormone cortisol spikes less in people who have solid support outside the marriage, which means those outside friendships literally soften the blow of conflict at home. Other research on middle-aged and older couples found that marital satisfaction was higher when each spouse stayed active in their own social circles, partly because it gave them support and energy they weren't demanding from each other. Keeping friendships beyond your husband stops you from turning him into your entire world. It's easy to put the person we love on a pedestal, and if we aren't careful, that overwhelming love can turn toxic. People often confuse caregiving with codependency.

Whereas codependency is measured by fear of abandonment, weak boundaries, and a constant need for control, healthy caregiving is flexible, loyal, and clear about its limits. Dedicated time with friends can prevent codependency and keep you from becoming overly clingy. But if your husband is going out constantly to avoid time together rather than add to it, that's its own kind of problem. The goal shouldn't be getting away from you, but spending real time with friends he trusts and enjoys. A healthy amount of space usually feels refreshing rather than threatening, and the strongest marriages make room for it.

Strong marriages seek out balance.

Boys' nights are a great chance for male bonding, but that doesn't mean they have to be secretive. An upcoming boys' night should come with transparency. Husbands should be glad to share what they're doing and who they're with: a wrestling night with their college friends, a baseball game with their brothers, or just dinner with a couple of guys after work. It also helps to have a rough idea of when he'll be home, so you're not up late worrying. One of the best parts of a boys' night is when your husband walks back in the door eager to tell you the night's best stories, a funny anecdote, or just that he missed you. That kind of sharing is its own sign of respect for the person you love.

On the other hand, women have a responsibility to trust their husbands too. When we take our wedding vows, we're agreeing to trust our partners indefinitely. That means respecting the male bond, not prying into their conversations or asking for a detailed account of every single thing that happened. In turn, husbands have a duty to honor their wives: they shouldn't lie about who they're with, spend the night at venues built around meeting women, or run with guys who don't respect their marriage. You don't need to obsessively check in on his friendships, but honest communication should run both ways. Boys' nights can be a genuinely good thing, but they can also expose trust issues.

What matters most is that your friendships aren't a way to escape your marriage. If your husband is out every single night, he's neglecting your marriage. And if you're spending all your free time with your girlfriends or out clubbing, you're neglecting him just the same. The time you spend together should still feel special, and worth protecting. You and your husband can be best friends, but you shouldn't feel like you're each other's only friends. At their best, boys' nights are a small exercise in trust, the kind that usually sends him home with a good story and a little more gratitude for you.
