When Love Hurts: Understanding Triggers, Trauma, and Affairs in Relationships

Relationships have a fantastic way of bringing everything to the surface: our capacity for joy, tenderness, and connection, but also our fear, shame, and pain. Even couples who deeply love each other can find themselves trapped in cycles of hurt, silence, anger, or distance that neither partner fully understands.

When this happens, most people assume something is wrong with them or with the relationship itself. But from a trauma-informed perspective, these painful moments are not signs of failure; they are signs that the body is trying to heal.

None of this is about blame. It’s about the nervous system and how it responds to closeness.

Whether you’re navigating everyday triggers or recovering from the devastation of an affair, the truth is the same: you are not broken. You are simply touching places within you that were never given the safety to be felt before. There’s a reason your relationship feels so intense—and there’s a way through it.

‍

The Body Remembers

Most people think triggers come from the present moment: a sharp tone, a forgotten promise, a look that lands wrong. But in trauma work, we understand something deeper: most triggers in relationships aren’t about your partner at all. They’re about your past.

Closeness awakens the body’s oldest memories—the preverbal imprints of times when love and safety didn’t coexist. Your body remembers what your mind forgot. It reacts before you have time to think, not because you’re broken, but because you’re trying to stay safe

Your reaction that feels “too big” or “irrational” is often the voice of an earlier self saying, “This feels like before.” Your body isn’t rejecting your partner; it’s protecting an old hurt.

The Younger You Who Still Lives Inside

Inside every adult is a younger part—what we call the Dissociative Child in PSIT. This wounded child is the part that froze when comfort wasn’t available, that hid when emotions felt too big, that learned connection can sometimes hurt.

When your partner does something that echoes those early experiences, that younger part can suddenly take over. You might feel panic, anger, shame, confusion, or an urge to withdraw. You might go numb, lose words, or feel small and helpless. This isn’t immaturity; it’s survival intelligence awakening.

It happens to both partners. One might collapse into fear of abandonment while the other retreats in fear of being consumed. Both are trying to protect themselves from a threat that no longer exists.

Two Nervous Systems Dancing

In every relationship, two nervous systems are constantly communicating beneath the level of words. When one person becomes dysregulated—triggered, defensive, or shut down—the other’s body senses it instantly.

This can create a looping dance of co-dysregulation:

one partner pulls away, the other feels abandoned and clings harder;

one raises their voice, the other shuts down, leaving the first feeling even more unseen.

Neither is “the problem.” Both are caught in an invisible physiological loop of protection.

The beauty—and the challenge—is that these same bodies can learn to co-regulate. With awareness and practice, the same connection that once triggered pain can become the very container for healing.

‍

Affairs Through a Trauma Lens

Few ruptures cut as deeply as infidelity. It dismantles trust, identity, and safety. But to truly heal, we must look beyond morality and into the body.

Affairs rarely arise from lack of love; they arise from lack of regulation. When someone’s nervous system is overloaded—numb, ashamed, or terrified of closeness—the body seeks relief. Sometimes that relief comes through intensity, secrecy, or fantasy.

The affair becomes a nervous-system strategy, not a conscious choice for betrayal. It’s the dysregulated self trying, however destructively, to feel alive again.

People often stray not because they stopped loving their partner, but because they couldn’t tolerate the parts of themselves that surfaced inside that love. They may feel unseen, inadequate, or suffocated. They may crave validation or intensity to escape their own internal collapse. None of these excuses the pain. But it does humanize it.

‍

The Impact of Betrayal

For the betrayed partner, an affair is not just heartbreak—it’s trauma. The body reacts as if its very survival is at stake: shaking, nausea, insomnia, intrusive images, panic, or emotional collapse.

Betrayal shatters the nervous system’s sense of safety. The world suddenly feels unpredictable, and the partner once associated with calm now becomes a source of alarm. This reaction isn’t overreacting—it’s biology. Your body is remembering what abandonment felt like long ago.

‍

Healing at the Level of the Body

Many couples try to talk their way through this pain, only to find themselves going in circles. That’s because the wound doesn’t live in the mind; it lives in the body.

Talking helps once the body is ready to listen, but not before.

Forgiveness can’t be forced from the head; it has to arise from a regulated nervous system.

That’s where Psycholytic Somatic Integration Therapy (PSIT) comes in. PSIT works directly with the body’s memory, where trauma, betrayal, and fear live, and helps each partner slow down enough to notice what’s really happening beneath the arguments.

Through this somatic approach, couples learn to pause the moment before reaction, to recognize when a younger self has taken the wheel, and to bring the body back into the present. They begin to experience that safety is possible again, not through words, but through nervous-system cues of consistency, transparency, and calm presence.

What Repair Looks Like

Repair after trauma or infidelity is not about returning to how things were. It’s about building something new, slower, steadier, more honest.

It means having real conversations at the right time, not in the middle of dysregulation.

It means clear boundaries without punishment, compassion without caretaking.

It means learning to sit in discomfort without fleeing or fixing.

As healing unfolds, couples often discover a depth of intimacy they never knew before.

They begin to say things like:

“We’ve never been this close.”

“I finally understand you.”

“We’re meeting each other as adults for the first time.”

‍

If You Were the One Who Strayed

Your path forward begins with accountability. Healing requires transparency, patience, and an open nervous system. Shame will try to shut you down—don’t let it. Learn what overwhelm feels like in your body. Stay present even when your instinct is to hide. Repair is built through consistent, embodied actions, not promises.

‍

If You Were the One Betrayed

You are not crazy. You are not too sensitive. Your pain is the body’s truth.

Healing means allowing yourself to feel safely, pacing your recovery, and rebuilding trust only when your body says yes. You deserve space to move at your rhythm—and to have your reality believed.

The Possibility of Healing

Some couples heal together, discovering a deeper partnership on the other side. Others choose separate paths but leave with greater clarity, self-awareness, and compassion. Both are valid.

Healing doesn’t depend on the relationship staying intact.

It depends on your relationship with yourself.

‍

The Deeper Truth

Everything you’re feeling—triggers, withdrawal, rage, numbness, confusion—is your nervous system trying to tell its story. It’s not proof of failure. It’s evidence of aliveness.

Love will always surface what still needs to heal. When two people are willing to meet that process with honesty and care, what once felt unbearable can become sacred ground.

You are not broken.

Your relationship is speaking.

And with presence, patience, and the right support, love can become not the place you hide from pain, but the place where healing finally begins.
