Chapter Twenty-six: Solo Polyamory, Insecure Attachment, and a Healthier Love
“The quality of any relationship is predicated on one’s relationship with oneself.”
Carl Rogers
Solo polyamory places a strong emphasis on autonomy inside the context of multiple intimate relationships. For some people, that structure genuinely fits their values. For others, the language of autonomy can hide fear, avoidance, or difficulty tolerating closeness. Those are not the same thing. As psychologist Carl Rogers wrote, “The quality of any relationship is predicated on one’s relationship with oneself” [368]. That line matters here because no relationship structure can do our inner work for us.
Solo Polyamory and Attachment Styles
Attachment patterns often follow people into adulthood [285]. Someone with a secure attachment style may value autonomy without fearing closeness. Someone with insecure attachment may use distance, intensity, or non-exclusivity in ways that reflect unresolved fear rather than honest preference.
Research on consensual non-monogamy suggests that avoidant attachment can be associated with greater willingness to engage in those structures [374]. That correlation is worth noticing, but it should not be overstated. Correlation is not causation, and no single relationship model belongs only to one attachment pattern [369]. Human beings are more complicated than that.
Dark Triad Traits and Relationships
The Dark Triad traits of narcissism, Machiavellianism, and psychopathy are associated with manipulation, reduced empathy, and self-serving behavior [370]. Research also suggests that people high in these traits may lean toward short-term mating strategies and exploitative patterns in relationships [371]. That reality matters because any relationship structure can be used well or used badly.
Solo Polyamory and Vulnerability to Dark Triad Traits
Polyamory and solo polyamory both emphasize negotiated freedom, autonomy, and non-exclusivity [372,373]. Those values can be practiced with maturity and care. They can also be misused by someone who wants the benefits of access without the burden of empathy, consistency, or accountability. If a person already leans manipulative or exploitative, a loosely structured relationship can become cover for selfishness rather than a framework for honesty [370,371].
Secure Attachment and Relationship Satisfaction
Across relationship structures, secure attachment remains one of the strongest foundations for relationship satisfaction [285]. People tend to fare better when there is trust, clarity, mutual respect, and enough honesty to name needs and boundaries directly.
That distinction is important. If someone behaves manipulatively inside solo polyamory, the problem is not automatically solo polyamory. The problem is the person’s character, motives, and capacity for ethical relating. A healthy structure still depends on healthy people.
Labels Do Not Hide Character
Solo polyamory is not automatically healthy and not automatically unhealthy. Like any other structure, it can be practiced with honesty, care, and maturity, or it can be used to avoid closeness, dodge accountability, or justify selfishness.
The deeper issue is not simply how many people are involved. The deeper issue is how each person relates to intimacy, responsibility, and truth. Secure attachment helps because it gives people more room for honesty, steadiness, and mutual respect [285]. Self-awareness helps because it makes it harder to hide fear behind a philosophy of freedom [368].
If solo polyamory truly fits someone’s values, that fit should show up in consistency, communication, boundaries, and care for the people involved. If it is being used as a shield against vulnerability, that will show up too. No label can hide character for long.
