When Dishonesty Shifts: Attachment Style And The Hidden Layer Of Recovery

There’s something I see over and over again in my work with couples navigating betrayal recovery, and I think it gets overlooked far too often in the addiction treatment world: the role that attachment style plays in the dishonesty that surfaces after the initial crisis has passed.

Let me explain what I mean.

The First Layer of Dishonesty

When a couple first enters treatment after the discovery of sexual betrayal or addiction, the lying and gaslighting that come to light are enormous. They are devastating. They are part of what I call the emotional and psychological injury of betrayal. And understandably, most of the early therapeutic work focuses on stopping those behaviors and establishing a foundation of honesty.

Here’s what’s important to understand: that initial lying, the elaborate secrecy, the gaslighting, and the distortion of reality is part of the addictive structure itself. It is the architecture of compartmentalization that allows a person to maintain a double life. It’s driven by shame, by the need to protect self-perception, and by the psychological defenses that were erected to keep the secret world intact. This is the dishonesty that gets dismantled during addiction treatment, during disclosure preparation, and during the early phases of recovery.

And when it works, it’s powerful. Disclosure, when done well, creates a critical pivot point, moving couples out of the devastation of staggered discovery and into the possibility of genuine repair. A foundation of honesty is laid. The secrets are told. And both partners begin to breathe again.

But here’s where it gets complicated.

The Second Layer of Dishonesty

As recovery progresses and the addiction-driven lying has been addressed, many couples find themselves bumping up against a different kind of dishonesty. This one is quieter. More subtle. Often about things that seem (on the surface) insignificant.

A partner in recovery might not mention a conversation they had, or fudge a small detail about their day, or leave out information that they know their spouse would want to hear. And the betrayed partner, understandably, feels the ground shift beneath them again.

“Are we back to square one?” they wonder. “Is the addiction just showing up in a new area?”

I get why it feels that way. After everything you’ve been through, any whiff of dishonesty can send your nervous system into overdrive. The body remembers what it’s like to be lied to, and it does not distinguish between a lie about an affair and a lie about whether your partner stopped for coffee on the way home. Your threat response system fires up, and suddenly you’re right back in the washing machine.

But here’s what I want to offer: in most cases, this second layer of dishonesty is not the addiction migrating to a new territory. It is something else entirely. It is attachment style showing up in the relationship.

How Avoidant Attachment Drives Dishonesty

Our attachment systems are psychobiological. They operate at an unconscious, bodily-based level that shapes how we relate to others, how we handle conflict, and how we manage emotional closeness. And attachment style has everything to do with how a person navigates honesty in a relationship, particularly when recovery has removed the addictive structure that was previously driving the deception.

This is especially true for individuals with an avoidant attachment style. As I describe in The Betrayal Bind, people with avoidant attachment learned early in life that expressing their needs, being vulnerable, or creating waves in a relationship would lead to punishment, withdrawal, or disconnection from their caregiver. As children, they learned to repress their needs and manage their inner world alone. John Bowlby called this coping strategy “compulsive self-reliance,” and it beautifully captures the essence of this attachment style.

As adults, avoidantly attached individuals carry an internal working model that assumes closeness will bring pain, danger, or overwhelm. They may not even recognize their own need for connection because they have spent a lifetime dissociating from it. And (and this is the critical piece for recovery) they have an intense, bodily-based fear of conflict.

For someone with avoidant attachment, the prospect of sharing information that might create tension, disagreement, or emotional intensity in the relationship can feel genuinely threatening to their nervous system. It is not a calculated decision to deceive. It is a knee-jerk, survival-level reaction. Their system says: conflict is dangerous, telling this truth will create conflict, therefore I must avoid telling this truth.

This can show up around things that seem tiny and insubstantial. Not mentioning that they ran into an old friend. Glossing over a purchase they made. Saying everything at work was “fine” when it wasn’t. Leaving out a detail that they know, somewhere in their body, will create a moment of friction.

And so they don’t tell. Or they hedge. Or they unconsciously omit. Not because they are protecting a secret life, but because their nervous system is screaming at them that honesty will bring the very disconnection and conflict that their attachment system has been organized since childhood to avoid.

Why This Matters for Couples

Here’s why understanding this distinction is so important for both partners.

For the betrayed partner, recognizing that this type of dishonesty has a different root cause than the addiction-driven lying can be enormously clarifying. It doesn’t make it okay. It doesn’t mean you shouldn’t feel hurt or frustrated or scared when you discover that information has been withheld. Your feelings are completely valid, and your need for honesty and transparency is non-negotiable for the rebuilding of safety in your relationship.

But understanding that this behavior is rooted in your partner’s attachment system rather than in active addiction changes the treatment focus. And that matters. Because these two types of dishonesty require very different interventions.

Addiction-driven dishonesty is addressed through addiction treatment focused on arresting the behaviors, dismantling the compartmentalized thinking, rebuilding integrity, and engaging in therapeutic disclosure. These are the tasks of early recovery, and they are essential.

Attachment-driven dishonesty, on the other hand, requires a different kind of work. This is relational work. It lives in the space between two people and in the nervous system of the person whose avoidant attachment is running the show. It takes longer. It is more nuanced. And it often requires significant work in couple’s therapy.

The Path Forward

So, what does this work actually look like?

For the partner in recovery who struggles with avoidant attachment, the work centers on learning to identify the fear when it arises. To notice the moment when their body says don’t tell, it will cause a problem. To recognize that impulse not as wisdom but as an old survival strategy that no longer serves them or their relationship. The work is about learning to hold that fear, to calm the dysregulation that floods their system when they anticipate conflict, and to make the brave choice to share the truth anyway, even about the small things.

This is not easy work. Remember, avoidant attachment is not a personality flaw. It is a deeply wired coping strategy that was developed in response to early relational experiences. Changing this pattern requires rewiring at the level of the nervous system, and that takes time, patience, and skilled therapeutic support.

For the betrayed partner, the work involves continuing to hold your boundaries around honesty while also expanding your understanding of what is driving the dishonesty you’re encountering. This is not about excusing the behavior, it’s about accurately diagnosing it so that the right treatment can be applied. When we misdiagnose attachment-based dishonesty as addiction-based dishonesty, we can end up going in circles, applying the wrong solution to the right problem.

For the couple, this is where couples therapy becomes essential. The relational dynamics that feed avoidant dishonesty (the cycle of withholding, discovery, activation, conflict, and withdrawal) are relational patterns that need to be interrupted and replaced with new ones.

Both partners need to learn new ways of being together: the avoidant partner learning to risk honesty even when their system is screaming to hide, and the betrayed partner learning to create enough safety that honesty becomes less terrifying for their partner’s nervous system, while still maintaining their own boundaries and self-care. This is the deep, tender, vulnerable work of relational recovery. It is the imperfect, courageous, deeply human work of allowing ourselves to know and be known in ways that repair old wounds, restore our sense of self, and reconnect us to safe relationship.

A Word of Caution

I want to be clear about one thing: if you are seeing patterns of out-of-control spending, financial decisions that don’t make sense, or other behaviors that feel compulsive and escalating, those are different red flags. Those may indeed point to the addiction expressing itself in a new area, and that warrants a conversation with your treatment team.

But if what you’re encountering is a pattern of small omissions, avoidance of difficult conversations, and a partner who seems genuinely committed to recovery but keeps stumbling over honesty in everyday moments, I would want to look at attachment style first. I would want to explore whether your partner’s nervous system is running an old program that says truth equals danger, and I would want that to become the focus of the therapeutic work.

Because when we understand the why behind the behavior, we can find the right path to healing. And that path, the one that leads through understanding our attachment systems, calming our nervous systems, and braving vulnerability with one another, is the one that leads to the deepest and most lasting change.

You’re not back at square one. You’re in a new chapter. And this chapter, while challenging, holds within it an extraordinary invitation: to build something between you that is more honest, more connected, and more securely bonded than what existed before.
