Almost every client who sits down across from me eventually asks some version of the same question: why do I keep doing this? Why do they shut down the moment a conversation gets hard. Why they need three texts back within the hour to feel okay. Why closeness, which should feel good, sometimes feels like the scariest thing in the room. The honest answer is usually attachment — a pattern formed so early in life that it now runs quietly in the background of every relationship, largely outside conscious awareness.
Where attachment styles come from
Attachment theory began with British psychiatrist John Bowlby and was later tested empirically by developmental psychologist Mary Ainsworth, whose "Strange Situation" studies with infants and caregivers identified distinct patterns of bonding — secure, anxious, and avoidant. In 1987, researchers Cindy Hazan and Phillip Shaver demonstrated that these same patterns persist into adult romantic relationships in remarkably similar proportions. A decade later, a nationally representative U.S. study by Mickelson, Kessler, and Shaver (1997) found that roughly 59% of American adults are securely attached, 25% avoidant, and 11% anxious, with the remainder falling into a disorganized or mixed pattern — numbers that have held up across dozens of replications since.
That means two out of every five adults are navigating relationships through some form of insecure attachment. It is not a flaw or a diagnosis. It is a strategy your nervous system built, usually in early childhood, to get its needs met with the caregivers it had. The trouble is that a strategy built for a five-year-old rarely serves a forty-five-year-old well.
The four attachment styles
Secure
Comfortable with both closeness and independence. Can ask for what they need directly, tolerate a partner's need for space without spiraling, and recover from conflict without it threatening the relationship's foundation.
Anxious (preoccupied)
Craves closeness and reassurance, and reads ambiguity as a threat. A delayed text can feel like abandonment. Often described by partners as "too much," when what's actually happening is a nervous system scanning for signs of rejection because, at some point, that scanning kept them safe.
Avoidant (dismissive)
Highly self-reliant, uncomfortable with emotional intensity, and quick to create distance when a relationship starts to feel demanding. Often described as "cold" or "unavailable," when what's actually happening is a nervous system that learned early on that needing someone was unreliable or unsafe.
Disorganized (fearful-avoidant)
Wants closeness and fears it in equal measure — often pulling a partner in and then pushing them away in the same week. This pattern is more common among people with a history of inconsistent or frightening early caregiving, and it tends to respond well to steady, patient therapeutic work.
Why this matters more than most people realize
Attachment style predicts far more than how someone acts on a first date. It shapes who people are drawn to, how long relationships tend to last, and how conflict gets handled once the initial spark fades. It also has a documented relationship to wellbeing outside the relationship itself — insecurely attached adults report meaningfully higher rates of anxiety and depression than securely attached adults, according to the same Mickelson, Kessler, and Shaver national survey. This is why I weave attachment work into couples therapy and individual therapy alike — it is rarely just a "relationship issue." It is a nervous system issue that shows up in relationships.
The good news: attachment style is not a life sentence
One of the most consistent findings in the research is that attachment style can shift with what's called a corrective relational experience — enough repeated moments of safety, consistency, and repair to teach the nervous system a new pattern. This can happen in a secure romantic partnership, in a strong friendship, or, for many of my clients, in the therapeutic relationship itself. Change is slower than a single conversation, but it is genuinely possible at any age.
A starting point, wherever you're reading this from
If you recognized yourself in one of these patterns, the next useful step is naming it out loud — to yourself, and eventually to the people closest to you. "I notice I get anxious and need reassurance when you're quiet for a while" lands very differently than an unexplained wave of clinginess or withdrawal. For those working through this on their own or from outside California, my 6-week Come Home to Yourself program and ongoing membership both dig into attachment patterns in depth and are available nationwide. For hands-on clinical work with me directly, I see individual and couples clients throughout California.
