There’s an assumption about married dating that goes something like this: weekdays are for the marriage, and weekends — those stolen Saturday nights, those long unhurried afternoons — are when the affair really comes alive.
It sounds plausible. Romantic, even. But ask anyone who’s been on a married dating site for more than a few months, and you’ll hear something quite different.
For a great many people, weekends are the loneliest part of the whole arrangement. And Sunday, in particular, is the quietly painful one.
Why the weekend assumption is wrong
Most affairs run on borrowed weekday time — a hotel on a Wednesday lunchtime, a Thursday-evening “drink with colleagues,” a Tuesday morning before work. These are the windows that exist. Weekends, by contrast, are when family life closes ranks. Saturday is school clubs and shopping and the in-laws coming for tea. Sunday is roast lunches and walking the dog and a film on the sofa with someone you’ve spent two decades sharing a sofa with.
What that means for an affair partner is simple. Saturday goes quiet. Sunday goes quieter. Messages slow to a trickle, then stop. The phone — which usually pings throughout the working week — sits face-down all weekend. By teatime on Sunday, more than a few people are sitting in their kitchens looking at it and feeling the kind of low, specific ache they didn’t know an affair could deliver.

What’s actually happening
It isn’t that one person has stopped caring. It’s that weekends impose a sudden, cold reality. A married person at a Sunday lunch with their family is not, in any meaningful sense, available — emotionally, practically, or otherwise. Two days earlier they were the most attentive, witty, present version of themselves. Now they’re a man at a barbecue with a tea towel over his shoulder, or a woman sat through her son-in-law’s golf monologue, completely out of reach.
That shift isn’t anyone’s fault. It’s the structure of the thing. But it lands hard on the affair partner, who spends Sunday evening drifting between Antiques Roadshow and the Sunday papers trying to work out whether they’ve imagined the whole connection.
Sarah from Bristol — 44, single after a long marriage, met her affair partner through Illicit Encounters last autumn — described it neatly when she emailed us. “Friday afternoon I’m someone he’d run away with. Sunday afternoon I’m a stranger he hasn’t thought about all weekend. And on Monday it starts up again as if nothing happened. After three months of that I almost ended it.”
She didn’t end it. But she did make some quiet adjustments. Most experienced married daters do.
The unspoken rules of the weekend
The first thing is to stop expecting the weekend to behave like the week. It won’t, and pinning hopes on it will only make Sundays worse. Once you accept the rhythm — busy and warm Monday to Friday, quiet at the weekend, busy and warm again from Monday — most of the weekend hurt eases off on its own.
The second is to fill the weekend with your own life. Not in the sad, performative way (“I’m fine, I’m fine, I’m so fine”), but actually. The married daters who fare best are the ones with full Saturdays — friends, gigs, family of their own, a long swim, a dinner booked with a sister, anything that means the day isn’t structured around a phone that isn’t going to buzz. People who treat weekends as something to be endured until Monday have a much harder time of it.
The third — and this is something the better affair partners learn early — is the gentle pre-weekend message. A short Friday note that says, in effect, “I’ll be quiet this weekend, but I’m here on Monday.” It costs nothing. It changes everything. Sundays get a great deal easier when you’ve been told, in advance, that the silence is just the silence and not the slow death of something.
Where Sundays really matter
There’s a reason long-running affairs tend to develop their own little Sunday rituals — a 9pm message after the kids are asleep, a single-word check-in over the kettle, a planned Monday morning coffee that gives the weekend something to point towards. None of that is accidental. It’s the response of two people who learned, somewhere around month three, that weekends need a structure of their own or they will quietly chip away at everything else.
That, more than anything, is what separates affairs that run for years from the ones that fizzle out by spring. Not chemistry. Not timing. Just a quiet understanding that Sundays are hard, and worth handling carefully.
If any of that resonates, you probably already knew most of it. We hear versions of it from members every week at IllicitEncounters.com — and if you’re in the early months of something and the weekends have started to feel heavier than you expected, you’re in very good company.
