ADHD and Relationships 101: ADHD makes my long-distance relationship hard

Say your partner is in another city. In the morning you think about writing to them, then you dive into the day. At noon they cross your mind for a moment, and you tell yourself you will write once you finish what you are doing. In the evening, when you pick up your phone, there is a single sentence on the screen: “I guess I didn't cross your mind at all today.”

But they did. Several times. It is just that none of those moments turned into a message.

This piece is part of the ADHD and Relationships 101 series, and it answers the question most often asked by someone with ADHD who is in a long-distance relationship. Long-distance relationships are not rare at all: people studying in different cities, people who moved for work, people who found each other online. For someone with ADHD, these relationships carry a difficulty of their own. Because the work that bodies, a home and a shared table do in a nearby relationship, at a distance, almost entirely has to be done by remembering.

Why a long-distance relationship feels harder with ADHD

First, the good news. Long-distance relationships are not as disadvantaged as people think. In a study that compared roughly seven hundred people in long-distance relationships with more than four hundred people living near their partners, very few differences came out between the two groups. Relationship quality was determined more by the characteristics of the people and the relationship than by distance (Dargie et al., 2015).

So distance alone does not break a relationship. But it changes the tools the relationship runs on. Two people living near each other see each other even if they never make a plan. At a distance, every contact requires something to come to someone's mind, a time to be matched and a screen to be switched on.

ADHD touches exactly these three points. Alongside attention and impulses, it also affects executive functions: keeping an intention in mind, remembering at the right moment something to be done in the future, tracking the passage of time (Barkley, 2015). That ADHD can continue into adulthood and can create difficulties in many areas of daily life is also included in the international consensus statement (Faraone et al., 2021). Relationships are one of these areas, and long-distance relationships are, I think, where this difficulty shows most clearly.

Seeming to forget the person you cannot see

In the ADHD community this is often called object permanence. The term actually comes from developmental psychology and describes babies learning that something that disappears from view continues to exist. Adults with ADHD, though, use it in a more everyday sense: food that goes into the cupboard gets forgotten, a bill that goes into a drawer does not get paid, work you cannot see does not get done. It is not a scientific diagnostic criterion, but it is a name that describes the experience well.

In a long-distance relationship, this name turns into a person. Your partner is not in front of your eyes all day. There is no mug of theirs at home, no shoes of theirs by the door. Most of the reminders that connect you to them have disappeared.

There is a fine distinction here. You are not forgetting your love. You are not forgetting your partner's existence either. What you forget is the intention “let me write to them now” coming back to your mind at the right moment. In research this is called prospective memory, and it is one of the areas people with ADHD often struggle with. The intention is set up in your head, but the first stimulus that comes along knocks it out of place.

From the outside, this distinction does not show at all. All your partner has in hand is a day that passed in silence.

Time blindness and time differences

In a long-distance relationship, time matters twice over. One, contact gets squeezed into certain hours. Two, sometimes two different time zones or two different daily routines have to fit each other.

With ADHD, time is often split into two zones: now and not now. The promise “I'll call in the evening” is still sitting in the “not now” zone in the afternoon. When evening comes, you are in the middle of something else, and that promise has suddenly slipped into the past. I described this mechanism from the relationship side in more detail in time blindness in relationships.

If there is a time difference, things get even more tangled. Your evening may be their midnight, your lunch break their meeting. You have to do mental arithmetic, and mental arithmetic is one more load on working memory.

Hyperfocus comes into this too. When you dive into something, the hours really do not pass; we talk about this separately in I get lost in hyperfocus and my partner feels neglected. For a partner who lives far away this feels sharper, because that missed call may be the only video conversation of the week.

Why closeness through a screen can be tiring

Most of a long-distance relationship happens on a screen. That is not a bad thing in itself. In a diary study that recorded the daily communication of long-distance and nearby couples, the long-distance couples had less contact during the day but disclosed more about themselves and saw their partners more positively. Their feelings of intimacy also came out at least as strong as those of nearby couples (Jiang and Hancock, 2013).

So distance does not automatically reduce closeness. But building closeness on a screen can ask a different kind of effort of someone with ADHD.

In a video call there is only a face and a voice. It looks as if there is no other stimulus around, but the phone itself is a notification machine. A message slides in and your eyes go to it. Your partner sees this instantly on the screen. A half-second glance that might go unnoticed if you were face to face can turn into “you're not listening to me” on a screen.

Then there is the matter of sitting down and talking. For some people with ADHD, doing nothing but talk for a whole motionless hour is hard, no matter how much they love the person. This is not coldness. It is attention wanting something to hold on to.

How it looks through your partner's eyes

Now think about the scene from the other side. Your partner cannot see you. They do not know how your day went, how tired you got, how many times you thought of them. All they have is the communication itself: how many messages came, whether the call happened on time, whether your attention was on them while you talked.

In a nearby relationship, love flows through many channels. At a distance, most of these channels are closed. That is why a delay, a silence, an absent-minded look can take on a disproportionate weight. The thought “they forgot” can easily slide into “they don't care,” and from there into the question “is there someone else?”

In a study with university students, those whose ADHD symptoms were high in both inattention and impulsivity had lower romantic relationship quality. This link was partly explained by difficulties with emotion regulation and hostile arguments (Bruner, Kuryluk and Whitton, 2015). The study is not specific to long-distance relationships, but it tells me something important: a large part of the problem comes not from the forgetting itself but from how the argument after the forgetting goes.

If your partner is sensitive to rejection, or if you are, this cycle can speed up even more. I wrote about this separately in rejection sensitivity in relationships.

What you can do: hand remembering over to a setup

My suggestion is this: instead of trying to think about your partner more, tie the contacts that show you are thinking of them to a setup. Remembering looks like a matter of willpower, but with ADHD it is more a matter of design. In the glossary this is called an external reminder: loading remembering onto your surroundings instead of onto your memory.

Ritual calls. Fix a few evenings a week. Same day, same time, roughly the same length. Say Monday, Wednesday and Sunday evening at nine, for forty-five minutes. Set a recurring alarm on your phone, and set the alarm ten minutes before the call so you have time to put down what you are doing. The power of a ritual lies in making the decision once and not having to make it again every time.

A daytime signal. A long chat in the morning is not necessary. One sentence, a photo, a voice note. If you tie it to something you already do every day, the chance of forgetting drops. If I were you, I would tie it to the first coffee: a “good morning” while the coffee is brewing. You can find the broader version of the question of replying to messages in I reply to messages late.

A shared calendar. Open a single calendar you can both see. Call times, important days, the next meetup and your partner's hard days should go in there. If they have an exam, a presentation or a doctor's appointment, put a reminder on the morning of that day. Asking “How did your presentation go today?” on the right day is, for someone far away, often worth more than a gift.

Tying the call to something. If just sitting and talking is hard, add an activity to the call. Eating at the same time, opening the same series at the same hour and watching it, talking while walking, cooking the same recipe in two kitchens. When your hands and eyes are busy, attention often returns to the conversation more easily. Turning off notifications for the length of the call is a small but effective step too.

The table below is a sample weekly rhythm that most couples can adapt:

Day	What	Length	Reminder
Every morning	One sentence or a photo	1 minute	First coffee
Monday	Video call	45 minutes	8:50 p.m. alarm
Wednesday	Eating together or a series	1 hour	8:50 p.m. alarm
Friday	Voice note or short call	10 minutes	Lunch break alarm
Sunday	Review of the week and a look at the calendar	30 minutes	8:50 p.m. alarm

This rhythm is not a list of rules but a starting point. Change it according to your working hours, the time difference and your own pace.

Routine instead of surprises

In long-distance relationships, romance is often associated with surprise: a package that arrives unannounced, a ticket bought at the last minute. For someone with ADHD, a surprise is actually a hard task. Because it requires thinking ahead, keeping it in mind without telling anyone, and acting at the right moment. All three of those steps put load on executive functions.

To me, what is stronger than surprise at a distance is predictability. Your partner knowing when the next call is and on what date the next meetup is makes the waiting bearable. There is a big difference between an unknown silence and “we'll talk on Sunday evening.”

You can put romantic gestures into the calendar too. A letter or a small package on the first Saturday of the month. Choosing the next meetup together at the end of each one. If making plans feels heavy to you, that is a topic of its own; we talk about it separately in my partner wants me to make plans.

Do not neglect tickets and travel either. What most often ruins a meetup is a ticket left until the last minute. Buying the ticket on the day the date is set, or at least writing the purchase day into the calendar, saves both sides a stressful haggle.

An example of an agreement written together

Putting the setup into a short text instead of keeping it in your head works. Not a long contract; a few sentences that sit on both your phones. Say something like this:

We talk on Monday, Wednesday and Sunday evenings at nine. If one of us is going to be late, they let the other know by half past eight at the latest. During the day there is a signal every morning, and we leave the long conversation for the evening. The date of the next meetup always sits in the calendar. If a message has not been answered, we first think “they may have forgotten,” then we ask. On the last Sunday of the month we look at this list together.

The most important line in this text, I think, is the second to last. The chance of forgetting does not go away, but how forgetting will be interpreted has been talked through in advance. When there is a delay, the argument shifts to which part of the agreement faltered, not to your character.

How to explain it to your partner

The best time is a calm moment; the worst time is right after a missed call. Any explanation given while the hurt is fresh sounds like a defense.

When you explain, name the mechanism, but do not hide behind it. Sentences like these can help:

“I think about you during the day. But the moment I think of you and the moment I could write often don't line up; something gets in between and that intention gets lost. This isn't about you, but I also understand how it makes you feel.”

“I'm not good at surprises, because thinking ahead and keeping it in mind is hard for me. But I'm really good at planned things. If we plan this together, I'll be a more reliable person for you.”

“If my eyes wander during a call, tell me. I won't get angry, I'll put the phone aside.”

Then always bring a concrete suggestion. The sentence “From now on I'll be more careful” is one of the promises that runs out fastest with ADHD. “Shall we open a shared calendar on Sunday evening?”, on the other hand, is something that can actually be done. There are more examples of explaining ADHD in general in explaining your ADHD to your partner.

When it is time to get help

If calls and messages keep turning into fights, if the two of you have been repeating the same argument for months, talking with a couples therapist can help; at a distance these sessions can be held online too, and does couples therapy work for ADHD gives an idea about this. If forgetfulness and trouble with time make your life harder not only in the relationship but also at work and at school, it would be good to talk about this with your doctor as well.

What I am left with

I think a long-distance relationship is not a test for someone with ADHD but a mirror. It makes visible the things the surroundings quietly carry when you live close by. In a shared home, dinner covers for the call you forgot. At a distance nothing covers for it. That is why the problems look sharper, but the solutions are clearer too.

If I were you, I would set aside the sentence “I need to think about them more.” You already do. What is missing is not the thought but the bridge where the thought turns into a message, a call, a ticket. Building that bridge not with willpower but with alarms, a calendar and habits is both less tiring for you and more reliable for your partner.

And I want to say one more thing: routine does not kill romance. A call that comes every Wednesday at nine can be one of the most romantic things in the world for someone waiting far away. Because what you give them is not a surprise but a certainty: they know you will be there on Sunday evening. At a distance, that is what is needed most.
