Most marriages don’t fall apart the way television shows it. There’s rarely a single thunderclap moment — no thrown plate, no slammed door, no dramatic confession in a hotel lobby. The endings we see in dramas make for good viewing, but bear almost no resemblance to how British marriages actually unravel.
What really happens is slower, quieter, and far easier to miss. A small distance opens up somewhere in year five. Another in year nine. By year fifteen the two people sharing a kettle and a mortgage might not even be able to tell you when things changed. They just did.
After more than twenty years of talking to married people who’ve ended up on a site like Illicit Encounters, a pattern emerges. There’s a kind of timeline to the drift — not a rigid one, not the same for everyone, but recognisable. Here’s roughly how it tends to go.
Years one to three: the easy years (mostly)
The early years are usually the easiest, even if there’s a wedding to recover from financially. Conversation comes naturally. Affection happens without thinking. Sex tends to be frequent enough that nobody’s counting. The flat is small, the future is wide open, and the small irritations — his snoring, her habit of leaving cupboard doors ajar — still feel almost endearing.
The seeds of the future drift are usually planted here, but they’re invisible. He realises he can’t quite tell her about a difficult day at work. She notices he doesn’t ask much about her family any more. Neither thinks anything of it.
Years four to seven: the silent renegotiation
This is when most modern British marriages quietly change shape. A child arrives, or doesn’t. A mortgage gets serious. One career takes off and the other slows down. The flat becomes a house. The holidays become functional rather than romantic. The conversation becomes logistical.
Sex doesn’t stop — but it starts to slot in around the edges of life rather than driving it. Affection becomes performative on birthdays. Date nights start being suggested rather than happening naturally. The marriage isn’t unhappy. It’s just quietly being renegotiated, often without anyone ever using the word renegotiate.
By year seven, many couples could tell you what they’ve stopped doing. But they couldn’t quite tell you when.

Years eight to twelve: the wallpaper years
This is the stretch most members describe with a strange resignation when they first message us. The marriage has become wallpaper. It’s there. It’s familiar. You barely register it.
The arguments are usually smaller than they used to be — about loading the dishwasher, or whether someone took the bins out — because the bigger conversations have stopped being attempted. Sex might happen every few weeks, or every few months, or vanish entirely without either party formally raising it. Whole evenings pass with nothing said that hasn’t been said before.
One reader, Hannah from Stockport, put it perfectly when she emailed us last autumn: “We weren’t unhappy. We were furniture.”
Years thirteen to twenty: the invisible cohabitation
This is often when people start typing things into search bars they would never have imagined typing five years earlier. “Is my marriage over?” “Why don’t I fancy my husband any more?” “How do I feel something again?” Not in a panic. Just curiously, late at night, in a quiet kitchen, while their partner watches the football two rooms away.
By this stage the marriage tends to function more like a respectful flat-share than a romance. You divide tasks, manage logistics, sometimes parent together. You might still love each other in the gentle, brotherly way that long cohabitation produces. But desire? Specialness? Being properly looked at? Most people in year fifteen couldn’t honestly say they remember the last time.
Years twenty-plus: the fork in the road
Something usually shifts after the twenty mark. The kids grow up and leave. A parent dies. A milestone birthday arrives and forces a quiet stocktake on a Sunday afternoon. Suddenly the question stops being theoretical: do I want the next twenty years to feel exactly like the last ten?
For some, the answer is yes — companionship is enough, and there’s real value in that. For many others, the answer is a wordless no. That’s often the point at which people start looking for something that belongs only to them — not to blow up the marriage, often, but to feel like a person again inside it.
Why this matters
None of this is a doomed timeline. Plenty of marriages drift and then come back. Plenty don’t drift much at all. But pretending the drift doesn’t happen — or that it must mean something is broken — helps nobody.
If any of this reads like a description of your own kitchen, you’re not unusual, and you’re certainly not alone. People who quietly recognise themselves in year fifteen are, by some distance, the largest group we ever hear from. Sometimes they want a conversation. Sometimes a coffee. Sometimes they just want to feel slightly more like themselves again.
