A friend once told me she’d known for four years. Four years of knowing, and she spent two of them redecorating the kitchen. New tiles, a better tap, a shelf for the cookbooks neither of them used. When I asked why she didn’t just go, she didn’t say “I love him.” She said, “It’s complicated.”
It always is. People don’t stay in miserable relationships because they’re weak or stupid. They stay because leaving costs something real, and the cost is rarely the thing outsiders assume. Here are the seven reasons that come up again and again, in roughly the order people tend to admit them.
1. The Sunk Cost Trap: All Those Years
Eleven years is a hard number to walk away from. It doesn’t matter that eight of them were fine and the last three were a slow grind of silence at dinner. The brain doesn’t do that maths. It counts the whole eleven and treats them like a deposit you’d be insane to forfeit.
Economists call it sunk cost fallacy. In relationships it feels less like an error in reasoning and more like loyalty. You think about the flat you rented together in your twenties, the dog, the holiday in Portugal where he learned to make proper coffee. Leaving feels like declaring all of it a mistake, which it wasn’t. It was just finished.
2. Money Makes the Door Heavier Than It Looks
This is the reason people whisper rather than announce. A joint mortgage. A car in both names. One savings account that’s been quietly fed by two salaries for six years. Leaving isn’t a decision, it’s a spreadsheet, and most people don’t have the stomach for that spreadsheet at 11pm on a Tuesday.
The practical answer is unglamorous and it works: before anything else, get a clear picture of your own money. Knowing what you actually earn, owe, and could afford on your own changes the question from “can I leave?” to “how would I leave?” That’s a far less frightening question, and sorting out your own finances instead of everyone else’s is a genuinely good place to start. A separate account with three months of rent in it has talked more people off the fence than any amount of journaling.
3. Fear of the Unknown Beats a Known Unhappiness
Psychologists call it status quo bias, and it’s not cowardice. A dull, familiar misery is predictable. You know how bad Sunday evening will feel. Being single again at 34 or 51 or 62 is a fog, and the brain hates fog more than it hates sadness.
So people build a case. What if there’s nobody else? What if I’m alone at Christmas? What if he’s actually right that I’m difficult? The unspoken part is that the current relationship already contains most of those fears. Plenty of people feel lonelier sharing a bed than they ever did alone.
4. Children, School Runs, and the 7:40am Logistics
Nothing complicates a breakup like a seven-year-old who needs to be at school by 8:20 and a nine-year-old who won’t sleep unless both parents are in the house.
Parents stay for reasons that are partly noble and partly not:
- They don’t want to be the one who split the family, even if the family is already split emotionally.
- Two households cost roughly 60% more than one, and someone has to pay it.
- The idea of another adult tucking their kids in, or another adult being unkind to them, is unbearable.
- They’re scared of the conversation with their own parents, who’ve been married 42 years and think divorce is a character flaw.
What’s worth knowing: children are far better at reading atmosphere than adults give them credit for. A house with two polite strangers in it teaches a lesson about love that nobody wants to teach.
5. The Good Weeks Keep You There
Intermittent reinforcement is the most effective trap in behavioural psychology, and unhappy relationships run on it. Three bad weeks, then a Saturday where he’s the person you fell for. Flowers, a joke that lands, a genuine hug in the kitchen.
That Saturday resets everything. You think: there he is. That’s the real one. The rest is a phase. And you spend another six months chasing Saturdays. A relationship that’s bad 50% of the time isn’t a relationship with a rough patch. It’s a coin flip you keep flipping.
Why the good days feel so convincing
Hope is a painkiller. It works fast, it wears off, and it doesn’t treat anything. Almost nobody stays because life is bad every single day. They stay because it’s bad most days and wonderful some days, and they’ve learned to average it out.
6. Your Whole Life Is Wound Around Theirs
There’s a version of staying that has nothing to do with love and everything to do with admin. The shared friend group. The Sunday lunch with his mother who genuinely likes you more than she likes him. The squash partner you only got because she was his colleague.
Identity gets tangled up in it too. You become half of something, and the idea of reintroducing yourself to the world as a single person feels like applying for a job you’re underqualified for. Some people also stay because leaving would mean admitting to a room full of people that the wedding they attended, the one with the string quartet, was the beginning of the end.
7. Actually Leaving Is Exhausting
People underestimate this one constantly. Leaving is not a moment, it’s a project. A deposit on a rental. A van and two friends on a Saturday. Dividing a kitchen into yours and mine, down to the garlic press. Changing your address on nine different websites. Explaining the same thing seventeen times to people who mean well.
When you’re already tired from being unhappy, a project of that size looks impossible. So you do the easier thing. You stay another month. And another.
What Actually Moves the Needle
Nobody leaves because a blog post convinced them, and I’m not going to pretend otherwise. But there are small, unglamorous moves that turn a vague fog into something you can look at.
Write down the specific things you’d need to change, not the feelings. “I need him to stop speaking to me like I’m slow” is checkable. “I need to be happier” isn’t. Then say it out loud to him once, clearly, without the argument. What happens next tells you more than another year of hoping.
Tell three people the truth, all of them at least an hour’s drive away from your shared life. Open a bank account in your own name if you don’t have one. Look up what a one-bedroom actually costs in your area, because the number is usually less terrifying than the imagined one. Talk to a therapist, not to fix the relationship but to work out what you’d want if nobody’s opinion counted.
And stop measuring the relationship against its own best day. Measure it against an ordinary Tuesday, because ordinary Tuesdays are what a life is made of. If the ordinary Tuesdays are quietly awful, you already have your answer. The only question left is how many more of them you want to spend.
