Somewhere between the group chat and the group text thread that never quite becomes a plan, a new category of friendship has taken hold — women who have known each other for years, who talk almost daily, who show up with soup when one of them is sick, and who have never once met each other's other friends. Therapists and sociologists have started calling it "parallel friendship": relationships that run deep but never intersect with the rest of a person's social world, existing instead in their own sealed lane. It's not a new phenomenon exactly, but the shape of it has changed, and the reasons women give for keeping their friendships siloed say something uncomfortable about how exhausting modern social life has become.
The friend you'd never introduce to your other friends
Ask around and the pattern repeats with striking consistency: a work friend who exists entirely within Slack threads and post-meeting vents, never invited to a birthday dinner. A college roommate who gets the unfiltered version of a bad week over the phone but has never met a partner of five years. A neighbor who waters the plants and knows about the miscarriage nobody else was told, but who wouldn't recognize the sister who visits every Sunday. Each relationship is real, often the realest one in a given week — and yet the walls between them stay up, sometimes for a decade or more, without either party ever suggesting they come down.
What's changed isn't the existence of compartmentalized friendships — people have always had a work self and a hometown self. What's new is how deliberately women are naming the separation as a feature rather than an accident, and how many are describing it not as a gap to close but as the only way they can afford to keep the friendship at all. On TikTok and in longer Substack essays, the phrase "friendship silo" has started circulating alongside a specific complaint: blending friend groups takes emotional labor that a lot of women say they simply don't have left to spend.
The maintenance math nobody talks about
A 2023 survey by Match's Singles in America project found that a majority of respondents said they'd let friendships lapse in the past two years, citing time and energy as the main barriers — not falling out, not moving away, just a quiet failure to maintain contact. Against that backdrop, the appeal of parallel friendships starts to make a kind of exhausted sense: a friendship that stays in its own lane requires less coordination than one folded into a shared social calendar. There's no negotiating who hosts Friendsgiving, no managing the awkwardness when two friends who don't naturally click end up seated next to each other, no risk that a joke that lands with one group falls flat with another.
Sociologist Marisa Franco, author of "Platonic," has written about how adult friendship increasingly competes with work, caregiving, and romantic partnerships for the same shrinking pool of hours — and unlike those other relationships, friendship carries no formal claim on anyone's calendar. Keeping friendships separate, in that framing, isn't avoidance so much as triage: it's easier to sustain five distinct one-on-one relationships that each require thirty minutes of attention than to sustain one blended friend group that demands constant social choreography. The math is almost embarrassingly simple once you say it out loud, which might be exactly why so few people say it out loud.
What gets lost when the lanes never merge
The trade-off is real, and it's worth sitting with rather than smoothing over. Blended friend groups build something a sealed-off friendship structurally can't: a witness network, the kind of overlapping social fabric where multiple people notice if you go quiet, where a partner gets vetted by more than one perspective, where a bad week gets triangulated instead of absorbed by a single confidant who's now carrying the whole weight alone. Women who keep every friendship in its own lane sometimes describe a specific kind of loneliness that has nothing to do with how many friends they have and everything to do with the fact that none of those friends know each other — so no one person has the full picture, and no one group can catch what a single friend, however close, might miss.
There's also a quieter cost that shows up at life's bigger, less plannable moments — a wedding, a funeral, a diagnosis — when the instinct is to gather people, and it turns out the people don't know how to be gathered together. One woman interviewed for a recent Cut essay on the topic described planning her own thirtieth birthday and realizing, with something close to panic, that none of her six closest friends had ever been in the same room; she ended up hosting three separate small dinners instead of one party, because merging them felt, in her words, "like introducing three different versions of myself who'd never agreed to meet."
Why some women are doing it on purpose now
Not everyone experiences the silo as a loss. For plenty of women, keeping friendships separate is a conscious boundary rather than a failure of effort — a way of making sure the friend who knows about the divorce doesn't also field questions about it from someone who wasn't supposed to know yet, or that the friend from the running club stays a running-club friend instead of absorbing the emotional weight of a friendship that was never meant to carry it. Compartmentalizing, in this reading, isn't avoidance; it's a form of consent, letting each relationship stay exactly the size it was built to be instead of expanding by default just because two people happen to be in the same city.
That version of the trend looks less like isolation and more like intentional design — the social equivalent of not merging every account into one, because some things function better kept distinct. The friend who gives blunt career advice doesn't need to also be the friend who saw you cry at your sister's wedding, and there's an argument that trying to make one person hold every version of you is its own kind of unfair ask.
The group chat that never becomes a group
Scroll through enough of these conversations online and a specific tension keeps surfacing: women who say they crave the built-in community of a merged friend group, the kind their mothers seemed to have effortlessly through church, a bowling league, or a decades-long book club, while also admitting they wouldn't actually know how to build one from scratch at thirty-four with a full-time job and a toddler. The nostalgia is for a social infrastructure that mostly doesn't exist anymore, not for the specific people who used to populate it — and rebuilding that infrastructure from five separate parallel friendships takes exactly the kind of coordinated effort the silo was designed to avoid in the first place.
Maybe that's the real story underneath the trend piece: not that women have stopped wanting a village, but that assembling one now requires deliberately doing the thing that made the silos feel necessary to begin with — introducing the running-club friend to the work friend to the college roommate, and hoping the extra effort turns out to be worth more than the peace of keeping them apart.
