How to stop overthinking in a relationship

Your partner’s reply came back as “ok”. Not “okay!”, not “ok x”, just the two letters. You’ve read it several times, scrolled back to compare it with last week’s messages, and checked whether they’ve been online since. Part of you knows they’re probably busy. Another part is already rehearsing the conversation in which it all falls apart.

You can stop most of this, though not by finding the answer you’re looking for. Overthinking in a relationship feeds on not knowing. Every extra check, and every round of “are we okay?”, calms it for a while and then lets the next doubt in. What helps is getting used to not knowing for a few hours, turning the big “what does this mean” questions into small practical ones, and telling your partner, once and plainly, what you’re working on.

Why a two-letter reply can take over your evening

Not knowing can be harder to bear than bad news. At University College London, 45 volunteers played a computer game in which they guessed whether a snake was hiding under a rock, and a snake meant a painful electric shock to the hand. The odds kept changing as they played. People felt most stressed, and their pupils and sweat showed it, when the chance of a snake was about even, more than when they were fairly sure what was coming.¹ A short message from someone you love can feel like one of those rocks.

Written messages also carry less than we think. In a set of American experiments, students wrote short messages meant to sound sarcastic, serious, angry or sad, then guessed how often the reader would pick up the tone. They expected to be understood far more often than they were, and the readers were too sure of their own reading as well. Knowing each other well didn’t fix it.² So when “ok” sounds cold, some of that coldness may be your own voice reading it.

Which of these sounds like you?

• You read their messages over and over
• You keep an eye on their mood
• You check their phone, their location or who they follow
• You keep asking whether things are okay

You read their messages over and over

Rereading feels like gathering evidence, but the message is the same on the tenth reading as on the first. Each pass only gives your mood of the moment another go at it.

Try this for a week. Read a message once, reply if it needs a reply, and leave the chat closed for an hour. If you still want to look after that, look once. Notice how strong the pull is when you close the chat, and how strong it is an hour later. Keep a short note, too, of what the worrying messages turned out to mean. After a few weeks you’ll have your own record to set against the next “ok”.

You keep an eye on their mood

A silent drive home, a short answer over dinner, a sigh in the kitchen, and you’re already working out what you did. The worry behind this has a name, attachment anxiety. In everyday words it means a steady fear that the people you love will leave or stop loving you. In a large national survey of American adults, about 1 in 9 people described themselves mainly this way.³

This worry also changes what people make of what they see. A researcher in the United States gave volunteers the same made-up moments from a relationship and asked them to explain each one. Volunteers with this anxious style came up with darker explanations, felt more upset, and described reactions more likely to start a fight, though the partner in the story had done exactly the same thing for everyone.⁴

When you catch yourself reading a mood, write down two other reasons for it that have nothing to do with you: a hard day at work, a headache, a worry about their mother. You don’t have to believe them. They’re there so the first explanation stops being the only one. If the mood lasts for days, ask about it once, in plain words (“You’ve seemed down this week, is something up?”), and take the answer you get.

You check their phone, their location or who they follow

Checking promises certainty, and a Dutch experiment suggests it does the opposite. Two psychologists had volunteers check a gas stove on a computer screen again and again. Afterwards their memory of the stove was as accurate as before, but it felt hazier, and they trusted it less.⁵ Going by that study, refreshing a partner’s location or scrolling through who they follow may work the same way: the more you look, the less any one look settles it. And looking at their phone without asking adds a secret of your own to the relationship.

Pick one kind of checking and put a simple rule on it, such as no location app for a week. The first days may feel worse, because the doubt is still asking for its usual answer. Write down what you feared you’d find, and look at that list at the end of the week.

You keep asking whether things are okay

“Do you still love me?” “Are we okay?” “You’d tell me if something was wrong?” Asking once is ordinary. Asking again soon after you’ve had the answer is what researchers call excessive reassurance seeking.

In two studies of young couples, the people who asked for reassurance over and over tended to be the ones high in attachment anxiety, and their partners noticed the asking.⁶ When another team put 16 studies together, they found a small link between this kind of asking and rejection by other people, clearest in how rejected the askers themselves felt.⁷ The answer “yes, we’re fine” settles the worry until the next quiet moment, and then the worry wants a new one.

Next time the question rises, write it down instead of asking it, and look at it later in the day. By then you’ll often know the answer from how your partner actually treated you in the meantime. If you still want to ask, ask once, and leave it there for that day.

Planning or overthinking?

Some thinking about your relationship is useful. Working out how to bring up money, or whether you’re ready to move in together, is planning. A long review of the research concluded that going over things tends to help when the thoughts stay concrete, on what happened and what you could do next. It tends to drag people down once it turns into big “why” questions about what it all says about you.⁸

So ask whether the thought ends in something you could do this week. “Should I ask if they’re free on Saturday?” ends in a message you can send. “Why am I never as important to them as they are to me?” ends nowhere, and it’ll still be there tomorrow. The same split runs through replaying conversations in your head, and the overthinking test shows how often your thoughts tend to go round in circles.

If the doubts turn up all day, give them a set time. In a small American trial, people who worried a lot kept their worrying to one half hour a day for two weeks, and afterwards they worried, tensed up and lay awake less than a comparison group.⁹ The worry time tool helps you set one up.

How to talk to your partner about it

Your partner probably feels the overthinking even without seeing inside it: the extra questions, the checking, the “what did you mean by that?”. It’s fairer to tell them what’s going on, once, than to keep asking around it. Choose a calm moment, well away from a message that has just set you off.

Talk about the habit, and leave their faults for another day. Something like: “I read a lot into short messages, and then I ask you if we’re okay. I’m trying to ask less. If I ask twice in one day, could you just say you’ve already answered and leave it there?” That gives them a part to play other than endless comforting, and it puts the work on your side.

If there’s one small change that would help, ask for it too. Maybe a quick message when plans change, or a word when they want a quiet evening, so the quiet doesn’t land on you as a verdict. A habit like that is easier to keep than a promise made in the middle of a worried evening.

Anxious attachment for life? A 59-year study found it usually eases

Online quizzes can make an attachment style sound like a blood type, fixed in childhood. An American study followed 628 people over many years, at ages from 13 to 72. On average, attachment anxiety was highest in the teenage years and early adulthood, then fell, most of all through middle and older age. Throughout adult life, people in a relationship scored lower on it.¹⁰ These are averages, and they can’t show whether the relationship eased the worry or calmer people found partners more easily. They do show it isn’t set in stone.

When the worry is about something real

Overthinking and being wrong are two different things. Sometimes a partner really has gone cold, or is hiding something, and the doubt is picking up on what you’ve seen. A worry built on things your partner has actually done, more than once, deserves a direct conversation. A worry built on a gap between messages deserves an hour’s wait.

If you can’t tell which kind you’ve got, write down only what happened this week, the things you saw and heard, and leave out what you think they meant. If the page is nearly empty, most of the worry is coming from you, and the steps above are the place to start.
