I’ve been part of a book club for a few years now where I’m the only man. It wasn’t by design, just how things worked out. And over that time, I’ve had the privilege of watching some incredibly capable, intelligent women open up about their lives in ways they say they rarely do elsewhere.

One evening, a woman in the group, let’s call her Diane, said something that stopped the whole table. “I have colleagues, neighbors, and people I chat with at the gym. But if something terrible happened to me tomorrow, I don’t know who I’d actually call.”

Nobody rushed to reassure her. Because I think, in that moment, a few of the other women recognized something uncomfortably familiar in what she’d said.

What struck me most was that Diane wasn’t shy. She wasn’t awkward in social situations. She was, by every measure, one of the most competent and composed people I’d ever met. And that, as it turns out, might be part of the problem.

Because research is starting to suggest that many women who lack close friendships aren’t struggling with social skills at all. They’ve simply spent so long being emotionally self-sufficient that they never learned how to need people in the way that builds real intimacy. And if that idea catches you off guard, stick with me.

Self-sufficiency can look like strength while quietly becoming a wall

Let me be clear: there’s absolutely nothing wrong with being independent. It’s admirable, actually. But there’s a difference between healthy independence and a deeply ingrained pattern of never letting anyone in.

Some women learn very early in life, whether through family dynamics, cultural expectations, or sheer necessity, that the safest option is to handle things on their own. They become the ones who hold everything together. The problem solvers. The people others lean on, but who never seem to lean on anyone themselves.

From the outside, it looks like they’ve got it all figured out. From the inside? It can be profoundly lonely.

A 2022 study published in Philosophical Transactions of the Royal Society found that women not only seek out social support more often than men but are also more sensitive to the absence of strong social ties. The researchers noted that women who don’t maintain close, confiding relationships often experience measurable declines in both psychological and physical wellbeing. In other words, the need for connection isn’t a personality quirk. For women, it appears to be deeply wired.

So when a woman who seems perfectly put-together tells you she doesn’t have close friends, it’s worth pausing before assuming she simply prefers solitude.

The “tend and befriend” response isn’t just a theory

Most of us have heard of the fight-or-flight response to stress. But back in 2000, psychologist Shelley Taylor and her team at UCLA discovered something fascinating: women don’t always follow that pattern. Instead, they often respond to stress by nurturing those around them and seeking out social connection, a pattern Taylor called “tend and befriend.”

The biological mechanism behind this involves oxytocin, sometimes called the bonding hormone, which is released during stress and appears to drive women toward connection rather than confrontation or withdrawal.

Here’s what makes this relevant. If women are biologically inclined toward seeking social bonds during difficult times, then a woman who consistently doesn’t do this isn’t just “introverted” or “private.” She may have overridden a fundamental stress response because, at some point, reaching out didn’t feel safe or didn’t produce results.

That takes a remarkable amount of effort to maintain. And it’s the kind of effort that can become invisible over decades. She just looks “strong.” But what she’s actually doing is suppressing an instinct that’s been part of female biology for thousands of years.

Capability can become a cage

I’ve seen this in my own life, though from a different angle. After I retired, I realized just how much of my social world had been tied to the office. I had to intentionally rebuild. And I’ll tell you, learning that male friendships require deliberate effort was a humbling lesson for a man in his sixties.

But for many women, the challenge isn’t finding people. It’s letting them in.

Think about it this way. If you’ve spent 30 years being the person everyone else turns to, the reliable one, the fixer, the one who manages the household, the career, the emotional labor for the entire family, then vulnerability starts to feel like a foreign language. You know how to give support. You’ve never learned how to receive it.

As I covered in a previous post, the ability to ask for help is a skill, not a weakness. But for women who built their entire identity around not needing to ask, dismantling that pattern can feel like pulling out a load-bearing wall.

4) Intimacy requires a kind of vulnerability that self-sufficient people often avoid

Here’s a question worth sitting with: what’s the difference between a friendly acquaintance and a genuine friend?

I’d argue it comes down to one thing: vulnerability. An acquaintance knows what you do for a living. A friend knows what keeps you up at night.

Research by Robin Dunbar, the evolutionary psychologist, sheds light on this. In a 2025 paper published in the Annals of the New York Academy of Sciences, Dunbar explained that women’s friendships tend to be more carefully selected and emotionally deeper than men’s, but also more fragile and demanding. They require significant cognitive and emotional investment to maintain.

That means the very qualities that make women’s friendships so rewarding, the depth, the emotional honesty, the mutual knowing, are also the qualities that make them impossible to build without vulnerability. You can’t get to deep connection by keeping everyone at arm’s length. You just can’t.

And for a woman who’s spent years being emotionally self-contained, the prospect of opening up can feel less like an invitation and more like a threat.

5) It’s not about having more friends, it’s about having deeper ones

There’s a concept in psychology called socioemotional selectivity theory, developed by Stanford psychologist Laura Carstensen. The basic idea, as outlined in her research published through the National Institutes of Health, is that as people age and begin to sense that time is limited, they naturally narrow their social circles. They stop investing in peripheral relationships and focus on the ones that carry real emotional meaning.

What’s interesting is that this isn’t decline. It’s strategy. Older adults who prune their social networks tend to report higher emotional wellbeing than those who try to maintain a wide web of acquaintances.

But here’s the catch for the self-sufficient woman: you can’t narrow down to your closest relationships if you never built close relationships in the first place. The theory assumes you have a rich inner circle to draw from. For women who’ve spent decades being their own island, the narrowing doesn’t leave them with a concentrated group of deep connections. It leaves them with almost nothing.

That’s not a character flaw. That’s a pattern that quietly accumulated over a lifetime. And it deserves compassion, not judgment.

6) The shift doesn’t require a personality overhaul

I want to be careful here because I’m not suggesting that every woman without close friends needs to reinvent herself. That would be both patronizing and wrong.

What I am suggesting, based on what I’ve read and observed, is that small shifts matter enormously.

My wife taught me this. After 40 years of marriage, I’ve watched her navigate friendships with a kind of grace I still don’t fully understand. But even she’ll tell you that her closest friendships didn’t happen by accident. They happened because she was willing, over and over, to say something honest when it would have been easier to stay polite.

For women who’ve built their lives around self-sufficiency, the shift might start with something as small as answering “How are you?” honestly instead of reflexively saying “Fine.” It might mean texting someone not because you need practical help, but because you want to share something you’re feeling. It might mean letting someone see you when you’re not at your best.

None of that requires becoming a different person. It just requires loosening the grip on the version of yourself that always has to be okay.

7) This isn’t about weakness, it’s about being fully human

I’ve been reading nonfiction for most of my adult life, and one idea that keeps resurfacing across books, studies, and decades of conversation is this: we are wired for connection. Not as an optional extra. Not as a luxury. As a fundamental requirement for health and happiness.

The women who end up without close friends despite being warm, intelligent, and socially capable aren’t failing at friendship. In many cases, they’ve simply been too good at carrying things alone. They got through difficult childhoods, demanding careers, and overwhelming responsibilities by relying on themselves. And nobody ever told them that the same strength that got them through those chapters might be the thing standing between them and the intimacy they quietly crave.

As someone who volunteers at a literacy center, I’ve seen how people can carry invisible struggles for years without anyone knowing. The women I’ve met who are learning to read in their fifties and sixties often describe a similar pattern: they got incredibly good at hiding the gap, at compensating, at managing alone. The skill they developed to survive became the very thing that kept help at a distance.

The parallel isn’t perfect, but the principle is the same. Sometimes the coping mechanism outlives the crisis.

Parting thoughts

If any of this resonates with a woman you know, or with you personally, the most important thing I can say is: your self-sufficiency isn’t the enemy. It got you here. But it doesn’t have to be the only tool you use going forward.

Connection is built in small, honest moments between two people willing to be seen. And it’s never too late to start.

So here’s what I’ll leave you with: who in your life have you been keeping at a comfortable distance, and what might change if you let them just a little bit closer?
