By Kim Ronan, LCSW, MPH, CST | AASECT Certified Sex Therapist | Beverly Hills, CA | About Kim
As a couples therapist in Los Angeles, I hear this concern almost every day: “We argue all the time, does that mean we’re wrong for each other?” Many couples come into my office afraid that frequent tension means incompatibility. They worry that love should feel calm, steady, and easy all the time. When it doesn’t, they assume something is failing. But part of understanding why conflict is growth is recognizing that these moments of tension often reflect deeper needs, shifts, and opportunities for connection rather than signs that the relationship is fundamentally wrong.
I want to gently challenge that belief. In my work, and through the developmental model therapy framework, I’ve seen again and again that conflict is often not a sign of failure. In fact, why conflict is growth becomes clear when we understand how relationships develop over time. The couples who grow stronger are not the ones who avoid conflict; they are the ones who learn how to move through it.
If you and your partner are stuck in repeating arguments, this doesn’t mean you should give up. It often means your relationship is asking for growth.
Why Couples Arguing Is More Normal Than You Think
Let’s start with something important: couples arguing is normal. Healthy, even. Conflict shows up when two people with different histories, needs, and nervous systems try to build a shared life.
Many couples tell me they worry because they fight about the same things:
- Emotional distance
- Sex or desire
- Parenting
- Money
- Feeling unheard
The problem isn’t that these topics keep coming up. The problem is that couples don’t understand why they keep coming up. That’s where the developmental model helps.
Rather than asking, “How do we stop fighting?” I ask, “What is this fight trying to change?” When couples understand this shift, conflict starts to feel less scary and more useful.
Why Conflict Is Growth, Not a Red Flag
One of the core ideas I teach clients is that conflict as growth is a natural part of intimacy. Growth always creates tension. Think about muscle growth; it requires resistance. Relationships work the same way.
Conflict often appears when:
- A partner is changing
- A need hasn’t been named yet
- An old pattern no longer works
- A new stage of connection is forming
The developmental model therapy approach explains that relationships grow in stages. Each stage brings new challenges. When couples resist these challenges, conflict gets louder. When they listen, growth happens.
So when clients ask me why conflict is growth, I tell them this: conflict shows where growth is trying to happen.
The Developmental Model Therapy Explained Simply
The developmental model therapy approach views relationships as living systems that move through stages. Each stage has a task. When the task isn’t completed, couples feel stuck.
This model helps couples:
- Understand why arguments repeat
- Identify their current relationship stage
- Reduce blame and shame
- Learn how to move forward together
Instead of seeing conflict as something to eliminate, this approach treats conflict as guidance. Next are a sample of the stages from the Developmental Model of Couples Therapy.
Stage One: Connection and Bonding
Early relationships are filled with closeness, attraction, and excitement. This is the fairy tales and rose-colored glasses phase. The stuff that love songs and romantic movies are made of. Partners focus on bonding and feeling safe together. Conflict often stays hidden here. We ignore our differences and that is needed to build a bond.
If this stage goes well, couples build trust. If needs are ignored or boundaries are unclear, tension may show up later.
In therapy, we often revisit this bonding stage to understand early patterns that still affect the present.
Stage Two: Differentiation and Power Struggles
This is where many couples panic. Your partner has shown a side of them you haven’t seen before. Disillusionment sets in. Differences become clearer. Arguments increase. Sexual tension may rise or fall. Partners feel misunderstood.
From a developmental view, this stage is required. Each person is learning how to stay connected while also being fully themselves. This is where couples’ arguments often peak.
If couples don’t understand this stage, they assume the relationship is failing. They want to get back to that bonded, symbiotic stage where love was easy.
If they do understand it, this stage becomes a doorway to deeper intimacy.
Stage Three and beyond: Stability and Deeper Trust
When couples work through power struggles, understand their differences and can dance between the “I” and the “We” of the relationship, it settles into something stronger. Communication improves. Repair becomes easier. Conflict still happens, but it feels less threatening.
This stage brings emotional safety, a stronger sexual connection, and mutual respect. It doesn’t happen by accident; it happens because couples learn how to be themselves IN relationship. They differentiate. They learn from conflict instead of avoiding it.
Why Couples Fight About the Same Things Over and Over
When the same argument keeps showing up about money, dishes, emotional distance, or parenting, it is not random. In the Developmental Model, repeating conflict signals an unfinished growth task, not a compatibility problem.
Repeating conflict often means:
- A boundary hasn’t been respected
- A need hasn’t been clearly expressed
- Fear is blocking vulnerability
The developmental model therapy approach helps couples slow these moments down and understand what’s underneath. Once the message is heard, the conflict often softens.
How Conflict Shapes Intimacy and Desire
As a sex therapist, I pay close attention to how conflict affects intimacy. Unresolved tension often shows up in the bedroom as low desire, avoidance, or pressure.
When emotional needs are unmet, bodies respond. When couples work through conflict with care, desire often returns naturally. Emotional safety fuels physical connection.
In my work as a sex therapist, I see this connection clearly. Couples who avoid emotional conflict often find that physical intimacy fades too, not because desire is gone, but because the body responds to unresolved tension. Working through conflict is, in many ways, the foundation for reconnection.
Sexual health and emotional growth are deeply linked.
What Happens When Couples Avoid Conflict
Avoiding conflict may feel safer in the short term, but it often leads to:
- Emotional distance
- Resentment
- Loss of desire
- Feeling alone inside the relationship
Conflict avoided doesn’t disappear; it waits. Growth delayed becomes pain later.
Couples who grow learn how to stay present during discomfort and repair after disagreement.
How I Work With Conflict in Therapy
In my sessions, I help couples:
- Identify their relationship stage and what growth is necessary to get to the next stage
- Understand the purpose of their conflict and get curious of what it’s asking of you
- Learn how to argue without harm by learning how to share about our experiences and hear about our partner’s experiences
- Practice repair and reconnection, whether that be healing from a betrayal or having sex after a long pause
This work is gentle but honest. Growth requires courage, but it also brings relief.
An Invitation to See Conflict Differently
If you and your partner keep circling the same argument and walking away more exhausted than resolved, you are not failing.
You are stuck in an unfinished growth task. Therapy creates the space to slow that cycle down, understand what is underneath it, and actually move through it.
If you are ready to stop repeating and start growing, reach out to book a session.
