One-liner: The earliest relationship becomes the template for every later one, and when that first bond is unsafe, the template it leaves can quietly wreck the ones that follow.
Also known as / related terms: John Bowlby’s attachment theory and maternal-deprivation hypothesis; Mary Ainsworth’s Strange Situation; secure, anxious/ambivalent, avoidant, and disorganized attachment styles; internal working models.
What it is: Psychiatrist John Bowlby proposed that human infants are biologically primed to form a close bond with a primary caregiver, and that the quality of that bond gets encoded as an “internal working model,” a largely unconscious template for what closeness, trust, and safety feel like and what to expect from other people. His early maternal-deprivation hypothesis held that serious disruption of that first bond has lasting developmental costs; his later, broader attachment theory refined this into a model of how different caregiving patterns produce different relational styles. Developmental psychologist Mary Ainsworth gave the theory its empirical backbone with the “Strange Situation,” a controlled laboratory procedure observing how infants respond to a caregiver leaving and returning. From it she identified secure attachment (the child, reliably comforted at home, uses the caregiver as a safe base and is soothed on reunion) and two insecure patterns: anxious/ambivalent (produced by inconsistent care, the child is clingy and hard to soothe) and avoidant (produced by cold or rejecting care, the child suppresses its need for comfort and appears indifferent). Researchers Mary Main and Judith Solomon later added a fourth, “disorganized” attachment, seen when the caregiver is themselves frightening or a source of both comfort and fear, leaving the child with no coherent strategy at all, drawn toward and terrified of the same person. These early styles are not destiny, but they show meaningful continuity into adulthood, shaping how a person handles intimacy, conflict, dependence, and threat for decades.
How it shows up later: Insecure working models feed several adult patterns in this guide. Avoidant attachment can underlie the emotional coldness and instrumental relationships of the Dark Triad and the disposable-alliance behavior of The Fickle Operator. Anxious attachment can drive validation-hungry, grievance-prone behavior. Disorganized attachment, the “come here / go away” template built around a caregiver who was both safe harbor and threat, is a plausible root for the volatile, idealize-then-attack relational style seen in Malignant Narcissism, where the same person is courted and then destroyed.
Why they do it: People largely run the relational template they were handed before they had words for it. An adult who keeps others at a cold distance, or who swings between clinging and attacking, is often executing an internal working model formed in a first relationship that made closeness feel unsafe, not making a considered present-day choice.
How to protect yourself:
- Expect the template to reassert itself under stress, warmth in calm periods does not predict how an insecurely attached person will treat you the moment closeness or conflict feels threatening.
- With the “come here / go away” pattern, do not read the “come here” phase as the real relationship and the attack as an aberration; both are the pattern.
- Keep your own stability independent of their swings, so that being alternately pulled close and pushed away does not become the axis your working life turns on.
- Knowing the behavior may run on an old template helps you stop taking the whiplash personally, while still holding a firm boundary against it.

Label note: Attachment theory is an established, heavily researched, empirically tested body of developmental psychology, one of the most validated frameworks in this category. It describes population-level patterns and continuities, not a diagnosis; you cannot read a specific adult’s infancy backward from their behavior, and attachment styles are known to be modifiable over a lifetime.
