Many couples come to therapy feeling confused about patterns around touch, conflict, irritability, or emotional distance. One partner may feel rejected. The other may feel overwhelmed.
Often, the missing piece is sensory processing.
Sensory sensitivities are common in adults with Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder. While sensory differences are part of the diagnostic criteria for autism (outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), many adults with ADHD also experience heightened or fluctuating sensory thresholds — especially under stress.
These differences are neurological. Not relational.
Understanding Sensory Processing in Adults
In autism, sensory differences are part of the diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition.
In ADHD, sensory differences are not part of the formal diagnostic criteria, but many adults report heightened sensitivity or fluctuating sensory thresholds — especially under stress or cognitive fatigue.
Common patterns include:
- Auditory overwhelm (background noise, overlapping conversations)
- Tactile sensitivity (unexpected touch, certain fabrics)
- Visual sensitivity (bright lights, clutter)
- Sensory seeking (movement, stimulation, music)
- Rapid flooding when overstimulated
These are nervous system responses — not character flaws, avoidance, or intentional rejection.
How This Shows Up in Couples
Physical affection may feel complicated.
A partner may deeply love their spouse and still pull away from touch because their nervous system becomes overstimulated. The other partner may experience this as rejection.
Conflict escalates quickly.
When sensory overload combines with emotional intensity, flooding happens faster. Drawing from the work of John Gottman, flooding makes productive conversation nearly impossible. What looks like “stonewalling” may actually be nervous system shutdown.
Daily friction builds up.
Noise levels, lighting, clutter, spontaneity, or differing needs for stimulation can quietly create chronic tension — especially in relationships where one partner is sensory seeking (common in ADHD) and the other is sensory sensitive.
The Emotional Impact
When sensory sensitivities go unnamed:
The sensory-sensitive partner may feel:
- Ashamed
- “Difficult” or high maintenance
- Afraid of disappointing their partner
- Chronically overwhelmed
The other partner may feel:
- Rejected
- Lonely
- Undesired
- Confused by inconsistency
Both partners suffer — even when love is strong.cal.
New Understanding
Instead of interpreting withdrawal as emotional distance, it can be more helpful to think about it this way:
“Your nervous system may be overwhelmed, and we need to understand what is happening inside the body and environment.”
This perspective reduces blame and helps couples work together. When sensory and emotional experiences are understood, partners can create more predictable affection, planned conflict pauses, and environments that support regulation and connection for both people.
Moving Forward
Neurodiverse relationships are not broken — they require understanding.
When sensory differences are recognized and respected, couples often experience more compassion, less reactivity, and deeper connection.
If you are navigating autism, ADHD, or sensory differences in your relationship, couples therapy can help you understand your patterns and build tools that work for both nervous systems.
In my work with neurodiverse couples, we slow down these moments of misinterpretation and build practical tools that support both partners.
