Where the idea comes from
In the 1950s and 60s the British psychiatrist John Bowlby argued that infants are born with a drive to stay close to a caregiver, not just for food but for safety. When the caregiver is reliably available, the child explores confidently. When availability is unpredictable or absent, the child adapts, either by protesting louder or by learning not to ask.
Mary Ainsworth tested this in the 1970s with the "Strange Situation", a short laboratory sequence in which a toddler is briefly separated from and reunited with a parent. How children behaved at reunion fell into recognisable patterns. Mary Main and Judith Solomon later identified a fourth, disorganised pattern.
In 1987, Cindy Hazan and Phillip Shaver asked readers of a Denver newspaper, the Rocky Mountain News, to complete a "love quiz". Adults' descriptions of their romantic lives mapped neatly onto Ainsworth's categories, and the proportions were strikingly similar. Adult attachment research was born, and it reached a mass audience through Amir Levine and Rachel Heller's 2010 book Attached.
The four styles in dating
Secure
Core belief: "I'm worth loving, and others are generally trustworthy."
- Texting: consistent, unbothered by small delays.
- Early dates: shows interest openly; can take a "no" without spiralling.
- Conflict: raises issues calmly and expects resolution.
Secure daters can seem "less exciting" to people used to uncertainty. That calm is often the point.
Anxious
Core belief: "I want closeness, but I'm not sure it will last."
- Texting: monitors reply times; may send follow-ups to quiet the worry.
- Early dates: falls quickly, sometimes before knowing the person well.
- Conflict: wants to resolve it immediately; silence feels unbearable.
Helpful move: pause before acting on the worry and ask, "What do I actually know?"
Avoidant
Core belief: "Depending on others is risky; I'm better off self-reliant."
- Texting: irregular; may go quiet after a particularly close date.
- Early dates: enjoys connection but resists labels and future talk.
- Conflict: withdraws, needs space, may minimise feelings.
Helpful move: name the need for space out loud instead of disappearing.
Fearful-avoidant
Core belief: "I want love, and love feels dangerous."
- Texting: bursts of intensity followed by silence.
- Early dates: strong attraction mixed with suspicion.
- Conflict: can swing between pursuing and shutting down.
Helpful move: slow pacing, explicit reassurance and, often, professional support.
The anxious–avoidant trap
One of the most recognisable dating loops pairs an anxious partner with an avoidant one. The anxious partner reaches for reassurance; the avoidant partner feels crowded and steps back; the step back confirms the anxious partner's fear, so they reach harder. Both are trying to feel safe, using opposite strategies.
Levine and Heller suggest this pairing is common partly because each person's behaviour feels familiar to the other, and familiar can be mistaken for chemistry. Recognising the loop is often the first step to stepping out of it.

Can attachment change?
Yes, and this is the most hopeful part of the research. Studies of "earned security" describe adults who had difficult early relationships but now relate securely. Three things seem to help:
A secure relationship or friendship
Repeated experiences of someone staying, responding and repairing can gradually update old expectations.
Making sense of your story
Research using the Adult Attachment Interview suggests that a coherent, reflective account of your past matters more than the past itself.
Therapy that works with attachment
Approaches such as Emotionally Focused Therapy, developed by Sue Johnson and described in Hold Me Tight, focus directly on attachment needs between partners.
Your style is a starting point, not a sentence. The aim isn't to become a different person, but to notice your reflexes early enough to choose a response.
