The Four Attachment Styles: What They Are and How They Show Up

How we connect with the people closest to us isn’t random. It’s patterned, shaped by our earliest experiences of closeness, safety, and need. Understanding those patterns is one of the most practical and illuminating things you can do in therapy. It often reframes years of relationship confusion into something that finally makes sense.

That’s where attachment theory comes in.

What Is Attachment Theory?

Attachment theory was originally developed by psychiatrist John Bowlby, who proposed that human beings are biologically wired to seek closeness with caregivers, not just for physical survival, but for emotional regulation and psychological safety. The quality of those early caregiving relationships, he argued, shapes how we learn to relate to others throughout our lives.

Bowlby’s foundational work established that children form an internal working model based on their early caregiving experiences, an unconscious template for how safe, available, and trustworthy they expect others to be. These templates don’t stay in childhood. They travel with us into adult friendships, romantic relationships, and the therapy room.

Building on Bowlby’s work, developmental psychologist Mary Ainsworth identified distinct patterns of attachment behaviour in young children through her now-famous Strange Situation studies. Her research described three original styles: secure, anxious, and avoidant. Later, researchers Mary Main and Judith Solomon identified a fourth: disorganized attachment, which captures a more complex pattern that doesn’t fit neatly into the other three.

In my clinical work, I often introduce attachment theory early on, not as a label to fix onto someone, but as a framework that helps clients understand themselves with more compassion. The question isn’t “what’s wrong with me?” It’s “what did I learn, and is it still serving me?”

The Four Attachment Styles

Bartholomew and Horowitz’s four-style model of adult attachment is one of the most clinically useful frameworks for understanding how early patterns carry forward into adult relationships. Here’s how each style tends to show up:

Secure attachment

Securely attached individuals generally feel comfortable with both closeness and independence. They can rely on others for support without losing themselves, tolerate conflict without catastrophising, and trust that relationships can withstand difficulty. 

Anxious attachment

Anxious attachment is characterised by a deep fear of abandonment and a hypervigilance to relationship cues. People with this style tend to seek frequent reassurance, read into small signals of distance, and feel a persistent undercurrent of worry that the people they love will leave. Underneath that anxiety is usually a core belief: I am loveable only if I work hard enough at it.

Avoidant attachment

Avoidant attachment looks like self-sufficiency from the outside, and often gets mistaken for independence. People with this style tend to prioritise independence, feel uncomfortable with emotional demands, and pull back when relationships get too close. Underneath is typically a belief that closeness is unsafe, or that needing others leads to disappointment.

Disorganized attachment (also called anxious-avoidant)

Disorganized attachment is the most complex of the four. It often develops when early caregivers were also sources of fear or inconsistency, meaning the person learned both to want closeness and to associate it with danger. The result is a push-pull pattern: longing for intimacy, and retreating from it at the same time. 

What I find in practice is that clients rarely fit into one neat category. Most people carry a primary style with elements of others, and that style can shift depending on the relationship. Someone may be relatively secure with friends and deeply anxious in romantic relationships, or avoidant in one context and more open in another. The goal in therapy isn’t to diagnose, it’s to notice the pattern and understand what it’s protecting.

How Insecure Attachment Shows Up in Adult Relationships

Insecure attachment is often associated with anxiety, depression, and difficulties with emotion regulation, making it one of the most clinically significant factors in adult psychological wellbeing. In relationships, it tends to show up in recognisable ways:

Anxious attachment may look like needing constant reassurance from a partner, feeling destabilised by silence or distance, or interpreting neutral behaviour as rejection. It can also look like over-functioning in relationships, working hard to be needed, to be good enough, to prevent abandonment.

Avoidant attachment may look like emotional unavailability, discomfort with vulnerability, or a pattern of exiting relationships before they get too close. It often gets mislabelled as not being “a relationship person”, when it’s actually a deeply learned protection.

Disorganized attachment often produces confusing and painful relationship patterns, the simultaneous craving for closeness and the inability to stay in it. It can look like self-sabotage, intensity followed by withdrawal, or a sense of never feeling safe regardless of how trustworthy the other person is.

I often see clients who arrive frustrated with themselves, repeating the same patterns across different relationships, with different people, and unable to understand why. Attachment theory doesn’t excuse those patterns, but it explains them. And that explanation is often the first real shift.

How Therapy Can Help

The good news is that attachment styles are not fixed. By recognising patterns in how we approach relationships, we can make intentional choices to challenge unhelpful tendencies, and therapy provides a structured, safe space to do exactly that.

In therapy, attachment work might include:

Using Cognitive-Behavioural Therapy (CBT) to identify and challenge the core beliefs underlying insecure attachment, “I will be abandoned,” “needing people is weak,” “closeness always leads to pain,” and begin building more realistic, flexible ways of relating.

Working with Dialectical Behaviour Therapy (DBT) skills to develop emotional regulation and distress tolerance, which are particularly important for anxious and disorganized patterns where emotional flooding can make intimacy feel overwhelming.

Processing earlier relational experiences and trauma that shaped the attachment pattern in the first place, not to blame caregivers, but to understand what was learned and why, and to update the nervous system’s read on what closeness actually costs now.

The therapeutic relationship itself is also part of the work. A consistent, attuned, boundaried relationship with a therapist offers a lived experience of what secure attachment (within a professional relationship, however) can feel like, often for the first time.

What I want clients to understand is that insecure attachment is not a life sentence. It’s a learned pattern, and learned patterns can change. The work is gradual, and it requires both insight and new experience, but people do shift. I see it regularly.

When to Reach Out

If you recognise yourself in any of the styles above, if relationship patterns have left you confused, exhausted, or repeating the same painful cycle across different connections, trauma-informed can help.

At Mantra Psychotherapy, we offer LGBTQ2IA+-affirming care and gay men’s therapy in Toronto and across Ontario. Attachment patterns developed for good reason. They can also change, with the right support.

Our clinic also offers LGBTQ2IA+ couples therapy to navigate attachment patterns within relationships.
