ADHD and Friendship: Why Friendships Fade

There is a message on my phone that has been waiting for a reply for three weeks. I love the person who sent it. I read the message, I built the reply in my head, I even built it twice. Still, I did not send it.

Before the diagnosis there was only one explanation for this: it must mean I do not care enough. I lived with that explanation for years, and each time I felt a little more ashamed.

On the friendship side, this is also the cycle I hear about most: you meet someone, and the first three months are very intense. Long conversations, frequent meetings, a closeness that forms fast. Then a week gets in between. Then a month. Then it is too late to call.

The reason is not indifference. But from the outside it looks exactly like indifference, and this is where the real problem begins.

Making is easy, keeping is hard

The review by Wehmeier and colleagues (2010) shows that difficulties in social functioning in ADHD have a marked effect on quality of life.

But when you look at the picture more closely the distinction becomes clear: making friends is usually not the problem. Keeping them is.

The studies that show this distinction best were done with children. Normand and colleagues (2013) observed children with ADHD and their self-chosen mutual friends in the laboratory and looked again six months later. In the friendships of the children with ADHD, closeness, reciprocity and satisfaction with the relationship were lower, and conflict was higher. So there was a friend; the texture of the relationship was different.

A systematic review that gathers the subject comes to the same place: in children and young people with ADHD, the number of friendships and the quality of friendships are generally found to be lower, and friendships last for a shorter time (Spender et al., 2023).

Here is a place where I have to be honest: almost all of these studies were done with children and adolescents. There are very few well-designed studies that look directly at adults' friendships. The mechanisms I describe below I draw from known symptoms and from my own observation; I do not present them as a measured finding.

The difference between not calling and not caring

Remembering to call is hard. Calling someone requires remembering to do something in the future. This is called prospective memory, and it is one of the areas ADHD struggles with most. It has nothing to do with remembering the past; "remembering by itself, at exactly the right time, something that is not in my mind right now but needs to be done later" is a different job, and that job falters.

The result is this: you truly miss someone and you do not call. Both can be true at the same time.

What is not seen is forgotten. Someone you do not see often drops out of mind. This is the human form of the object permanence matter, and it has a side that produces guilt.

Interest starts intensely. A new person is a novelty, and in ADHD novelty is a strong source of motivation. In the glossary, bonding intensity. When the novelty fades, the interest drops too, and for the other side this looks like a sudden cooling.

Answering a message is a separate threshold. Writing a short "okay" is easy. A long, emotional message or one that asks for a decision goes into a waiting queue and stays there. I covered this separately in the article on email and message paralysis in ADHD; in friendship the cost is heavier, because the other side is waiting for your answer, not an institution's.

Not calling does not mean not caring. But from the other side the two look completely the same.

Difficulties during conversation

Interrupting. You cut in because you know you will forget what comes to mind if you do not say it. The reason is understandable, the effect is still hurtful. In the glossary, interrupting.

Oversharing. When the filter works slowly, information that does not yet belong at that level of closeness can get shared. The regret that follows is common. In the glossary, oversharing.

Missing things while listening. While the other person is speaking, your mind catches on one sentence and you do not hear the rest. Then the question that was asked has to be repeated.

Jumping between topics. A quick move from one topic to another is a lively conversation for some people and a flow that cannot be followed for others.

Running out of social battery. The crash that comes after a long meeting is real, and it leaves a person unwilling for the next meeting. I described that side in the article on social battery in ADHD.

The emotional side

The meta-analysis by Beheshti and colleagues (2020) shows that difficulties with emotion regulation are common in adult ADHD.

In friendship the counterpart of this is: an unanswered message, a canceled plan or a facial expression can produce a disproportionate pain. Its name is rejection sensitive dysphoria, and it often leads to quietly drifting away.

What appears in the glossary as quiet withdrawal comes into play here: reducing contact instead of saying you were hurt.

In me it works mostly in this form: when a message gets a late answer, my mind immediately builds a story, the "they are fed up with me" story. The time between building that story and believing it is very short. The only thing I have learned is to wait a day before believing that story.

How the other side reads this

There is a part here that most articles skip. Friendship is for two people, and the other side has no information at all about your inner world.

What they see is this: three months of intense interest, then silence. A forgotten birthday. Not being asked about your illness. A plan postponed three times. With this data, the most reasonable explanation to build is "they do not want me anymore."

Accepting this was hard for me, because I wanted my intention to be seen. It is not seen. The only thing that is seen is behavior. The common mistake is exactly here: explaining your intention without changing your behavior. The sentence "this is how I am, sorry" works for a while, and then it does not.

What works

Hand remembering over to a system. A recurring reminder in the calendar: once a month, call this person. It is common to find this cold; in fact it is the opposite, the most concrete way of keeping the relationship going.

Keep a small number of relationships regular. Instead of irregular contact with twenty people, regular contact with three. In ADHD capacity is limited, and accepting this raises the quality of the relationships.

Set a fixed rhythm. Coffee on the first Saturday of every month, a phone call every Tuesday evening. A fixed time removes the burden of making a plan each time.

Choose side-by-side activities. Instead of sitting facing each other and talking, doing something together: walking, working, cooking. Activities done side by side go on much more comfortably in ADHD.

Manage interrupting. Write what comes to mind on a piece of paper, then say it. Taking notes prevents both forgetting and cutting in.

Take special days out of memory. Birthdays, anniversaries, condolences, get-well wishes. These are what hurt most when they are not remembered, and all of them can be written into a calendar. The details are in the article on forgotten special days.

Explain, but briefly. The sentence "when I haven't called for a long time it does not mean I have forgotten you, I find it hard to remember to call" works in most friendships.

After a long silence Trying to write an explanatory paragraph to someone you have not called for months leads to never sending the message at all. A single sentence is enough: "It's been a long time, you're on my mind." Most friendships can bear this.

When to look beyond this

Not every kind of drifting from friendship is explained by ADHD.

If withdrawal from people has gone on for months, if nothing you used to enjoy gives any enjoyment now, and sleep and appetite have changed too, the picture resembles depression. If there is anxiety lasting for days before meeting, sweating, a pounding heart and the thought "I'll make a fool of myself," social anxiety is a separate heading. Both are often seen together with ADHD, and both have treatment. Diagnosis and treatment decisions are a doctor's job; this article is not a substitute for that evaluation.

If meeting new people is itself hard, the article on meeting new people looks at that part in detail.

A part that has to be accepted

Not every relationship can be kept going, and this is not entirely ADHD's fault either. People drift apart, lives change.

The distinction is here: a friendship you lost because you forgot and a friendship that ended naturally are different things. The first can be worked on; for the second, blaming yourself is unnecessary.

Back to the three-week message

I finally sent that message. There was no explanation in it, and no apology. It was a single line.

What did me good was not the reply but what I noticed after sending: what had kept the message waiting for three weeks was not indifference, it was the shame that grew in those three weeks. As the shame grows the message gets harder, and as the message gets harder the shame grows. What breaks this cycle is not finding a perfect sentence, it is sending a short sentence right away.

I covered the side of close relationships in the article ADHD and relationships.

There is a post in the diary about good people: The presence of good people.
