Can ADHD Affect Romantic Relationships? Simple answer: yes.

ADHD can have a real impact on romantic relationships, but I think we often talk about ADHD too narrowly.

We tend to think about ADHD as a difficulty with focus or attention. That is certainly part of it, but for many people, ADHD is also very much about regulation. It can affect attention, emotions, impulses, energy and how someone responds to stimulation. Shifting gears can be difficult, so can stopping once something has captured your attention or finding your way back to regulation once an emotional response has taken over. These are difficult for any human in relationship but can be particularly challenging for those with ADHD.


Being in a relationship means building a life with another person. There are shared responsibilities, expectations and routines. There is also the trust that comes from knowing you can rely on each other.

This is where ADHD can cause added complications as it affects some of these areas. ADHD can start to have an impact on the relationship due to forgetfulness, difficulty with motivation, inconsistency or challenges with regulation can affect how each person experiences responsibility and reliability... And this is where it can get complicated.


In my work with couples, I often see the impact ADHD has on the relationship dynamic. What interests me is not just what one person is doing, but what starts to happen between the two people as they respond to it.

  • A forgotten commitment might lead to frustration.

  • That frustration can lead to more reminders.

  • The reminders can begin to feel critical.

  • The person receiving them may become defensive or withdrawn, which can create even more frustration.

  • Over time, both people can become caught in something that feels much bigger than the original issue.

The couple starts to develop an understanding of what these moments mean.

  • “My partner always forgets. They don't care.”

  • “I can't rely on them.”

  • “I have to remind them about everything.”

  • “They are always on my back.”

  • “They don't understand how hard this is for me.”

These stories are understandable but they are not facts. They come from real experiences but once they become part of the relationship, they can start to shape how each person sees the other.


Looking at ADHD as part of the relationship


This is where I think couples therapy can be particularly helpful.

Couples therapy is particular in the sense that we do not focus on individuals but rather the patterns within the relationship. I am not there to figure out which partner is the problem, or to teach one person how to manage the other.

Instead, I often think about ADHD as a third.

There are two people in the relationship, and there is ADHD as another factor that can influence what happens between them. It means we can look at the role it is playing without making either person the problem.

Yes, ADHD makes certain things harder, but working against our partner also makes things harder. Maybe the relationship has adapted around those difficulties and maybe those adaptations have created resentment or an imbalance in responsibility. Maybe repeated frustration has changed the way each person experiences the other, but we can learn to rewrite that story.


Rather than getting stuck trying to determine whether something is “because of ADHD,” I often want to understand what happens between the couple when ADHD becomes part of the picture.

  • What happens when something is forgotten?

  • What happens when one person becomes overwhelmed?

  • What happens when reminders start to carry frustration?

  • What happens when that frustration begins to feel like criticism?


Those moments tell us a lot more about what is possible.

Looking at ADHD through a relational and nervous system lens


My work with couples is informed by both PACT and Somatic Experiencing, and I find that these approaches work particularly well together when ADHD is part of the relationship.

PACT gives me a way of looking closely at what is happening between two people. Rather than focusing on one person's behaviour in isolation, we can slow down the interaction and see how each person is responding to the other. Somatic Experiencing adds another layer to that work by helping us pay attention to what is happening in the nervous system while this is taking place.

This matters because we can understand our patterns very well and still find ourselves repeating them.

A couple might know that reminders lead to defensiveness, or that feeling criticised leads to withdrawal, and still find themselves in the same interaction the next time something happens. When we are activated, it can be difficult to access what we know when we are calm.

When in session, I can help couples slow that process down.

We can notice what happens when something is forgotten, when frustration enters the conversation, or when one person begins to feel misunderstood. We can look at the meaning each person is making of the moment while also paying attention to what is happening in their bodies and nervous systems.

This gives us more information than simply asking, “Is this because of ADHD?”

Maybe ADHD is contributing to difficulty with attention, follow-through or regulation. We can acknowledge that without allowing it to become the entire explanation.

A missed commitment is still a missed commitment. It may have a real impact on the relationship. At the same time, the story that develops around it , “you don't care about me” or “I can never do anything right”, is something we can explore together.


In conclusion, yes, ADHD can have a real impact on our relationships. But the way we approach it matters.

When we only look at ADHD as an individual difficulty, we can miss what happens between two people as they try to navigate it together. The frustration, the adaptations, the misunderstandings and the stories that develop over time can become just as important as the original ADHD-related difficulty.

In couples therapy, we can look at all of this together. We can understand what ADHD brings into the relationship while also paying attention to the patterns that have developed around it.


The goal isn't to find someone to blame or to make ADHD disappear. It is to help the couple understand what is happening between them so they can begin to approach these challenges as a team.


Because who we are alone isn't the whole story.
