Dear Therapist, We Used to Get Along, but Something Changed: A Relationship Scenario

The Letter
I have been with my partner for several years, and we once felt deeply compatible. Recently, even small differences have turned into frequent arguments, leaving us both tense and exhausted. There is no single dealbreaker, but I am beginning to wonder whether we are simply too different. Can we learn to navigate these differences, or are we fundamentally incompatible?
My Response
I see this in two ways. On one hand, conflict can be incredibly painful and exhausting. Yet, on the other hand, it can signal an important transition and an opportunity for growth in a relationship.
You may once have felt more compatible with each other, but every long-term relationship eventually requires partners to face their differences. Ultimately, the relationship becomes a crucible that refines these differences into something purer.
This is where differentiation becomes necessary. It is the ability to maintain a grounded sense of yourself while remaining emotionally connected to your partner.
This involves developing four important capacities:
- Managing difficult thoughts and emotions
- Enduring discomfort in the service of values
- Responding from a grounded position
- Maintaining a flexible yet solid sense of self
As human beings, we have urges for both attachment and autonomy. Yet, sometimes we lean on one more than the other. One of the biggest lessons to learn in marriage is the ability to balance these two urges.
Often, the most common problem is having too much of one without enough of the other. We either feel suffocated in the relationship or feel unable to be yourself. Learning to balance these urges of autonomy and attachment is called differentiation.
Instead of seeing conflict as evidence that you are incompatible, consider what it may be asking each of you to develop.
Make it your shared mission to understand each other's experience more deeply without get lost in the traps of who is right and wrong.
From my perspective, compatibility is not about having fewer differences; it is more about understanding each other's experiences and being able to stand on your own.
