There are many reasons why defensiveness is a favorite topic of mine, but when it comes to couples therapy, the reason is that it often feels like the “third party” in the room.
Defensiveness shows up like an uninvited guest who plants itself right in the middle of the couch. Suddenly this loving, well-meaning couple — who moments ago were simply trying to talk, to get closer, to understand each other better — finds themselves rudely interrupted by this third figure playing psychological monkey-in-the-middle. They’re no longer responding to each other; they’re reacting to its tone, its urgency, its fear, its speed. And in that instant, they lose sight of one another because this third presence has taken over the interaction.
How to spot it
You can see defensiveness most clearly in the split second after one partner gives the other feedback. Instead of pausing, considering the perspective, and sorting through what does or doesn’t resonate, the nervous system jumps straight into protection mode. In that moment, you’ll often see a quick justification or explanation, a shutdown, or a shift in focus to your tone, your delivery, or something you did “wrong.” In other words, the partner moves away from the discomfort of being confronted and toward whatever feels safer in that instant.
What it’s saying
At its core, defensiveness is a form of self-protection. People become defensive when they don’t feel enough psychological safety to sit with something vulnerable. When you share something with your partner, and are immediately met with defensiveness, it’s probably you’ve touched a tender spot — a place linked to shame — and the instinct is to cover it as quickly as possible.
Other times, defensiveness may show up when a partner reflects something we haven’t yet become conscious of in ourselves. Having someone suddenly name or illuminate an unflattering truth can feel startling, even exposing. Instead of leaning into that discomfort, the instinct is to push away the person who brought it to light. In this way, defensiveness isn’t really a refusal to hear a partner; it’s a reflexive attempt to protect a sense of self that feels threatened.
How we work with defensiveness — rather than against it — in couples therapy
When we begin to see defensiveness as the third party in the room rather than a personal flaw, everything changes. It becomes something to notice, to name, and to understand — a signal pointing to what’s tender and important beneath the surface.
In couples therapy, I help partners acknowledge defensiveness without judgment, explore what it’s trying to protect, and gently set it aside so they can connect with each other. With curiosity and practice, couples can move past reactive patterns, creating space for empathy, trust, and real intimacy. In this way, defensiveness doesn’t have to block closeness — it can actually guide us to it.
