Attraction and Rejection: a Neurobiological Response

Connecting is a fundamental human need. From the moment we take our first breath, we rely on others to survive. We seek closeness, safety, and recognition. But what if past experiences have taught us that connection can also be painful? That the person who comes close can also be the one who rejects, abandons, or hurts?

For people with trauma, closeness can be something to long for but also something to fear. The nervous system, wired to detect and avoid danger, may respond to connection as a threat. This creates a dynamic of attraction and rejection: the need for closeness sparks a desire, but once that closeness is there, it also triggers the memory of danger. The body and mind go into protection mode—pushing away, creating distance, sometimes abruptly or in a way that confuses the other person.

What Does Pushing Away Look Like?

Pushing away can happen in different ways, depending on how someone has learned to protect themselves. Sometimes it is visible and direct, while other times it is subtle and hidden.

• Active rejection: This may take the form of anger, criticism, distant or harsh remarks, or even creating conflict on purpose to push the other person away. This often happens unconsciously, driven by a need to stay in control: “If I push you away first, you can’t leave me.”
• Withdrawal and isolation: Instead of actively rejecting the other person, someone may become invisible. This can mean avoiding contact, keeping conversations superficial, being emotionally distant, or completely cutting off communication—also known as ghosting. For the other person, this often feels like rejection or a lack of interest, when in reality, it is a protective mechanism.
• Ambivalent behavior: Some people switch between seeking closeness and pushing away. There is a deep need for connection, but once it happens, fear takes over. This can result in mixed signals—first openness and warmth, then sudden distance or withdrawal. This can create confusion and insecurity for both the person with trauma and the other person.

Misinterpretation in Mainstream Psychology

In mainstream psychology, these responses—especially in extreme cases—are often interpreted as symptoms of a personality disorder, such as borderline personality disorder, or as mood swings associated with bipolar disorder. The behavior is then seen as irrational or as a deviation from the norm.

However, it makes far more sense to understand this as a neurobiological response. The nervous system reacts to connection based on what it has learned from past experiences. This is not about a conscious choice or a fixed pattern of “problematic” behavior, but about the body’s attempt to protect itself from (perceived) danger. This perspective allows for more understanding and nuance, rather than an immediate diagnosis or judgment.

The Cycle of Rejection and Confirmation

Often, the other person takes this distancing personally—as a sign of disinterest, emotional unavailability, or even a lack of love. This can lead to them pulling away as well, concluding that the person who alternates between seeking closeness and pushing away is at fault. But this, too, is a form of self-protection. In this way, the deepest fear of the person with trauma—rejection, misunderstanding, and abandonment—is reinforced. A vicious cycle develops where both people feel unsafe, even though the distancing is not about unwillingness or a lack of care.

What If We Understood This Better?

When we recognize this dynamic as a neurobiological response rather than a conscious decision, we can respond differently. Instead of judging the behavior or withdrawing ourselves, we can communicate: “I see you. I’m not leaving. I’ll give you space, but I’ll stay in contact.”

This doesn’t mean sacrificing yourself or ignoring your own boundaries, but rather remaining present with more understanding and gentleness. Sometimes, this means taking a step back without breaking the connection by saying something like:

• “I’m here, and I’ll stay close in a way that feels safe for you.”
• “I see that this is difficult for you. I’m here, and we’ll find a way that feels okay together.”

These words allow space without creating pressure, so the other person does not feel the burden of deciding when things are “okay again.”

A Different Experience of Connection

When someone, despite their automatic urge to withdraw, keeps experiencing that connection can be safe, space is created for a different experience. This doesn’t start with responding perfectly but with staying present, noticing, and allowing space.

A trauma-informed perspective helps soften and strengthen relationships, allowing us to see behavior with more understanding. We can learn that distance does not always mean rejection and that closeness is not always a threat. But also that, as the other person, you can be there for someone in survival mode without crossing your own boundaries. Step by step, in small moments, a new foundation of safety and trust can be built—for both people involved.
