There is a particular kind of romance plot doing the rounds at the moment — the one where two people who have been circling each other finally end up under the same roof, and the comedy comes from everything that happens after the keys are handed over. It lands because it is true. The falling in love part is the easy bit to dramatise. The part nobody films is the negotiation over which sofa goes and which stays, and whose morning routine wins the bathroom at half past seven.
Moving in together in your thirties, forties or fifties is a completely different project from doing it at twenty-two. You are not merging two duvets and a milk crate of books. You are merging two functioning lives, each with its own logic, its own friendships and its own way of loading a dishwasher. That is not a reason to avoid it. It is a reason to talk more before the van is booked.
Decide whose home it becomes — out loud
The single most common source of quiet resentment is one person moving into the other person's home and everyone pretending it is now neutral territory. It isn't. The walls have a history. The mugs have a history. The person who arrives with three boxes and no say in the shelving will feel like a long-term guest, and guests are always slightly on their best behaviour, which is exhausting.
If one of you is moving in, build in real ownership from the start. Not a drawer — a room, or at minimum a wall, a chair and a say in something visible. Take something out to make room for what arrives. If the home you are joining has not lost a single object to accommodate you, you have not actually moved in yet. And if you can possibly manage it, a third place that belongs to neither of you solves this problem elegantly, if expensively.
Money needs a system, not a vibe
Couples who have been independent for years often arrive at cohabiting with strong instincts about fairness and no shared vocabulary for it. Some want strict halves. Some want proportional-to-income. Some want one pot for the house and separate accounts for everything else. All of these can work. What does not work is leaving it vague and hoping it evens out, because the person who quietly pays for the washing-up liquid, the birthday cards and the new shower curtain is keeping a ledger whether she means to or not.
Have the unromantic conversation before you sign anything: what counts as a joint cost, who pays it, and what happens if one of you earns less next year. Then put a note in the calendar to revisit it in six months. Systems drift. Revisiting is not distrust; it is maintenance.
Protect the rhythms you built alone
Everyone has small, unglamorous habits that keep them steady — reading until late, a Sunday morning alone in the kitchen, a weekly call with a sister, going for a walk after a hard day instead of talking about it. When two lives merge, those habits are the first casualty, because they look optional next to togetherness. They are not optional. They are the reason you were good company in the first place.
Say them out loud early, in plain terms: "I need an hour when I get in before I'm any use to anyone." "I like to see my friends on Thursdays and it isn't about you." Framed in advance, these read as self-knowledge. Discovered later, they read as rejection.
How long should you date before living together?
There is no number that protects anyone, and couples who have waited years still get surprised by each other's relationship with the thermostat. What matters more than duration is whether you have seen each other under strain — illness, a bad work month, a family crisis, a cancelled holiday — because that is when a person's real defaults show up. If everything so far has been weekends and restaurants, spend a few longer stretches together first, ideally in one another's actual homes rather than somewhere neutral and lovely.
What if one of us owns the place and the other doesn't?
Name the imbalance rather than politely stepping around it, because it shapes the power in the house whether you discuss it or not. Agree what the person moving in contributes, what they are entitled to change, and — the awkward one — what would happen if you separated, including how much notice each of you would give the other. Writing that down feels grim on a Sunday afternoon, but it is a kindness to your future selves, and if the property side is significant it is worth getting proper legal advice rather than relying on goodwill.
