Psychology suggests their bond isn’t anchored by routine roles or responsibilities - it’s sustained by continuous choice, attention, and emotional renewal.
Psychologists who study long-term relationships have noticed something odd about couples without children. When they make it past the twenty-year mark, they tend to score higher on measures of relational satisfaction than parents at the same stage — and they report doing more work on their relationship, not less. The shared project most couples lean on was never available to them, so they built something else instead.
I was reminded of this last Saturday night. We had friends over for dinner in Thao Dien — a couple we've known about four years, together for seventeen, no kids, not through difficulty but through choice. Across the table, under the yellow kitchen light, I noticed something I'd seen before without ever being able to name it.
They don't talk like other couples I know.
There's a texture to how they interact that the long-married parents I know have mostly lost. A curiosity about each other that hasn't calcified. Questions that weren't logistical. Not "did you call the electrician" or "what time is daycare pickup," but "what did you think about that thing your brother said last week?" They looked at each other when they talked.
My wife and I used to talk like that. Then our daughter arrived.
What parents don't have to build
Having a child is, among many other things, the gift of a permanent shared project. An infinite well of things to coordinate, worry about, celebrate, and plan. It provides what relationship researchers call shared meaning almost by default. Every day contains a hundred small co-authored decisions. Vaccination schedules. School uniforms. Which grandparent is visiting when. Whether the child is too old for the teddy on the shelf. You don't sit down and decide to build a life together — the life assembles itself around the child, hour by hour, and you are both there inside it, mostly too tired to notice.
John Gottman's research, built on four decades of studying couples at the University of Washington's so-called Love Lab, identifies shared meaning as the seventh of seven principles that predict whether a marriage will endure. Lasting marriages, Gottman argues, are not held together by logistics. What holds them is a private culture — rituals, symbols, a way of naming things that only the two of you use.
For couples with children, that inner life is supplied in a constant drip. You don't have to manufacture it. The child is the ritual.
For couples without children, none of that scaffolding is free. If they want shared meaning, they have to build it. From scratch, deliberately, and again and again.
The research actually supports this
A large study conducted by the Open University in the UK, called Enduring Love?, surveyed over 5,000 people across England and the United States. Childless couples reported being happier in their relationships and with their partners than parenting couples. And here's the line that stuck with me for weeks. They were doing more work on their relationships than parenting couples were.
More work.
Dr Jacqui Gabb, one of the study's co-authors, noted that when asked who was the most important person in their lives, mothers often answered "my children" while fathers answered "my partner." Relationship maintenance, in other words, is something the childfree have kept paying deliberate attention to, because nothing else was going to do it for them.
An Institute for Family Studies analysis of more than 40 years of General Social Survey data found that 68 percent of childless women without kids at home are happy in their marriages, compared to meaningfully lower rates for mothers with kids at home. The effect, the analysis notes, is substantial.
I'm not saying one path is better than the other. I'm saying the numbers point to a very specific skill one group has developed out of necessity, and that the other group often hasn't.
The Buddhist angle
In Pali Buddhism there is a concept called mettā, usually translated as loving-kindness. It is one of the four brahmavihāras, the sublime dwellings. What's interesting about mettā is that it isn't love that comes from shared history, or shared biology, or shared projects. It's love as its own practice. Love as something you generate, not something that accrues to you as a byproduct.
Parenthood, as I've experienced it in Saigon over the last few years, makes a certain kind of love very easy. You love your child. You love your partner partly because she is the co-author of this small person you both adore. The love flows through the shared project. That is a real gift, and I don't minimise it.
But it can also make mettā-style love, the kind that exists as a practice rather than a byproduct, go quietly unused.
This is a thread I've tried to pull on in my book Hidden Secrets of Buddhism: How To Live With Maximum Impact and Minimum Ego. The practices that look the most useless, the ones that don't seem to be producing anything, are often the practices that keep us awake.
What childfree couples know
Watching our friends that night, I realised what they had quietly developed.
It wasn't better communication, exactly. It was something more basic. They had built a muscle that knew how to generate interest in each other on purpose. They treated each other as ongoing mysteries, not as co-administrators of a household.
They had to. Nothing else was going to do it for them. No school milestones to compare notes on. No parent-teacher night to attend as a team. No shared biological investment pulling them back toward each other every time adulthood pulled them apart.
What they had instead was seventeen years of deliberate attention. Trips they chose because they wanted to, not because the school calendar demanded it. Rituals they invented — a Sunday morning coffee at a specific cafe in District 3 — because nobody was going to invent those rituals for them.
The honest admission
I'm a father. I love my daughter more than I have words for. Nothing in this article is an argument against having children.
It's an observation about a skill.
The skill is the capacity to generate shared meaning with another adult, in real time, across decades, without the help of a joint biological project doing most of the work for you.
Most parents I know have lost some of that skill. Not because they're worse partners, but because they had a gift that made it optional for a while. The child kept the relational machinery running while they weren't looking.
Our friends left around eleven. The plates were still on the table. My wife and I cleared them together without saying much, and I found myself wondering whether what I'd seen in them was something we could still reach for, or whether the window for that kind of attention only opens when nothing else is standing in its way.
I don't know the answer to that. I'm not sure the research does either.
