Who do you really want by your side through life's most difficult passages?

At 66, caring for an aging husband while navigating my parents' heartbreaking journey with dementia, I've been asking myself this question more and more. And here's what I've discovered:

The person I might need most in my later years, the one who sees me most clearly and supports me most fully, might not be the man I married 36 years ago. It's more likely to be one of my closest women friends.

Beyond the Boundaries We've Been Taught

A couple of weeks ago, I shared research on the architecture of female friendship and how these relationships naturally evolve through the seasons of our lives.

Today, I want to push into uncomfortable territory: What if we stopped treating friendship as secondary and started building our lives around these relationships instead?

Recently, I discovered Rhaina Cohen's book "The Other Significant Others: Reimagining Life with Friendship at the Center." It articulates something I've been circling around for years without naming it.

Cohen profiles people who've made friends, not romantic partners, the center of their lives.

We're talking about cohabitation, shared finances, caregiving through illness, legal arrangements, and co-parenting. The whole architecture of committed life partnership.

Without romance or sex.

The Weight We Place on Romantic Love

You and I have weathered enough seasons to see the cracks in our cultural narrative: Find your "one true love," build everything around that romantic partnership, and let friendships drift to the margins.

But what if that script has been setting us up for profound loneliness?

While beautiful and valuable, romantic love struggles under the weight we've placed on it. We expect our romantic partners to be our primary emotional support, sexual fulfillment, intellectual stimulation, caregiving arrangement, financial partnership, and social anchor.

That's a lot to ask of one relationship. Maybe too much.

Cohen calls this cultural mandate compulsory coupledom—the notion that a long-term monogamous romantic relationship is necessary for successful adulthood.

But where has it gotten us? High divorce rates. Profound loneliness even within marriages. And so many older women caring for partners while their own needs go unmet.

My Personal Investigation

Let me be honest about why this matters to me right now.

My husband is older and has health challenges. There's a real possibility I'll outlive him by a decade or more, and we don't have children together. My solo aging is a legitimate concern. I need to think practically about my future.

Although he's doing relatively well and we love each other, I notice something: My closest friends know my fears about future finances and caregiving duties that I  can't share with him. They know my anxieties about my parents' decline in ways my husband doesn't.

My friends and I process losses and grief together, celebrate wins, and understand each other's particular fears. When life feels overwhelming, they're who I need most. Even though they're scattered across hundreds of miles right now.

What if, instead of treating these friendships as secondary to my marriage, I honored them as equally essential?

The cultural programming in my head immediately protests. But when I quiet that voice and listen to my deeper wisdom, it makes perfect sense.

What This Actually Looks Like

Cohen's book profiles people living this reality. Friends who've moved together across continents. Friends who've been primary caregivers through organ transplants and chemotherapy. Friends who are co-parents, co-homeowners, and executors of each other's wills.

These platonic partnerships, as psychologist Eli Finkel calls them, exist in a space our culture barely acknowledges. They have no ceremonies, few legal protections, and precious few models to guide them. Yet they're creating profound, lasting commitments.

Here's my favorite example from the book:

Barb and Inez met as office mates decades ago. Over time, Barb became deeply intertwined in Inez's family life, helping raise Inez's two sons, one of whom called Barb his "Angel Mom."

Today, in their eighties, they live together in the home they jointly purchased about 25 years ago upon retiring. They initially made the decision for economic reasons—neither could afford a home independently—but their shared household has become the foundation of a deeply interdependent chosen family.

They've each granted the other medical and legal power of attorney, serve as primary caregivers for one another, and have structured their later lives around mutual support and emotional companionship rather than traditional marriage or blood ties.

The Practical Side

So what would it look like to deliberately build life with friendship at the center?

Maybe it means living near your closest friend instead of following adult children to their cities. Perhaps it's creating legal documents that give your friend medical decision-making power. Maybe it's openly discussing the possibility of sharing a home when solo living becomes impractical.

Where I Am Now

I don't have this figured out yet. I'm still married and value my marriage. But I'm no longer pretending one relationship can or should meet all my needs.

I intend to have ongoing, honest conversations with my closest friends about the future—what we each need as we age, what living arrangements might serve us, how we can protect and formalize our commitment to each other, whether we're in romantic relationships or not. (Read the book to explore possibilities.)

It feels both unusual and utterly natural, like finally acknowledging what's been true all along.

Because these days, I can see with clarity that, separate from my husband, the most stable, nourishing relationships in my life are my close friendships.

The ones that ask less, offer more, and create space for my whole, authentic self.

An Invitation to Reflect

Who actually knows your deepest fears and greatest hopes? Who sees you most clearly and loves you despite your flaws?

And what would shift if you treated that person not as your "best friend" but as your other significant other? What conversations might you need to have? What legal protections might you want to establish? What dreams might you dare to share?

The world tells us that friendship is lovely but secondary. What if we trusted our own experience instead? What if we honored the relationships that actually sustain us rather than those we're "supposed to" prioritize?

There's no single right answer—just the invitation to be honest about what you need and who provides it. To imagine a future where friendship isn't an afterthought but a foundation.

I don't know what my eighties or nineties will look like. As a happy introvert, I hope to live alone for as long as possible while nurturing my important relationships. I crave solitude more than most. But I'm also realistic: eventually, I'll need people close by.

And I'm beginning to imagine a future where chosen family becomes essential—not because someone is obligated to stay, but because we decided we belong together.
