The Couples Who Love Each Other — Just Not Under the Same Roof

They've been together for 23 years. They've never broken up. They've never lived together. And they have no plans to start.

Mike and Susan aren't an anomaly or a cautionary tale. They're a data point in a quiet but steady shift in how people are choosing to build long-term relationships — on their own terms, in their own spaces.

Their arrangement has a name: Living Apart Together, or LAT. And it's more common than most people assume.

What the Numbers Actually Show

Between 2000 and 2019, the number of married couples living separately rose by more than 25 percent in the United States. Researchers and relationship writers like Vicki Larson — whose book LATitude explores the trend in depth — argue that this isn't a sign of relationships falling apart. It's a sign of people designing relationships more deliberately.

The trend skews older. People in their 50s and 60s, many of them retired, many with adult children and established lives, are disproportionately choosing this model. They've often been through a previous marriage or long-term partnership. They know what cohabitation costs — not just financially, but in terms of autonomy, compromise, and the slow erosion of personal space.

For this group, a separate home isn't a consolation prize. It's a feature.

Why This Is Happening Now

The timing isn't accidental. Several structural forces have converged to make LAT not just possible, but appealing.

Longevity is the big one. A 62-year-old starting a new relationship today may have two or three decades ahead of them. The question of how to spend that time — and with how much independence — carries real weight. The old script, written for shorter lifespans and fewer options, doesn't automatically apply.

Financial independence matters too, especially for women. When staying in a relationship no longer requires sharing a household for economic survival, the decision to cohabit becomes a genuine choice rather than a default. That changes the calculus entirely.

There's also the practical tangle of late-life assets. Merging households often means merging finances, complicating inheritance, and navigating the expectations of adult children from previous relationships. Keeping separate homes can simply be the cleaner arrangement.

Not Everyone's Convinced

Critics of the LAT model raise fair concerns. Separate households can mean separate support systems — which matters when someone gets sick, loses a job, or faces a crisis that demands presence, not just proximity. There's a version of LAT that functions as emotional intimacy with a built-in escape hatch, and some relationship researchers worry that it allows couples to avoid the deeper work of genuine interdependence.

There are also legal gaps. In most jurisdictions, LAT partners — even long-term ones — lack the automatic rights that come with marriage or even recognized cohabitation. Medical decisions, inheritance, hospital visitation: these can become complicated in ways that couples don't always anticipate.

And then there's the cultural weight. Even in societies that celebrate individual choice, there's a persistent assumption that a relationship is only serious if it's heading toward a shared address. LAT couples often find themselves having to justify their arrangement to family, friends, and institutions that weren't built with them in mind. The Apartners Facebook group — a private community for LAT couples — exists partly because these couples needed a space where they didn't have to explain themselves.

What It Says About Us

The rise of LAT isn't really about couples who don't want to commit. It's about a growing recognition that commitment can take more than one shape. The model we've inherited — meet, date, move in, marry — was designed around particular economic realities, life expectancies, and gender dynamics that have shifted considerably.

The question LAT raises isn't whether these couples love each other less. It's whether the structures we use to measure love have kept pace with the lives people are actually living.
