Your attachment style is part of the answer
Being single doesn't mean something is wrong with you. But if you keep finding yourself alone despite wanting a partner, or if you repeatedly end up in the same kind of relationship that doesn't work, the pattern is worth examining. Attachment theory, developed by John Bowlby in the mid-20th century, offers a framework for understanding why. Your attachment style—the way you relate to closeness, vulnerability, and trust—shapes who you're drawn to, how you behave in relationships, and whether those relationships last.
Bowlby discovered that the bonds you form early in life create templates for how you expect relationships to work. If someone was reliably there for you as a child, you learned that vulnerability was safe. If they weren't—or if they were inconsistent, critical, or demanding—you learned differently. Those lessons don't stay in childhood. They follow you into adult relationships, influencing who you choose, what you tolerate, and when you walk away.
The attachment styles and what they cost you
Adult attachment comes in four main patterns. Phillip Shaver and Cindy Hazan developed this model in the 1980s, and Chris Fraley expanded it into the ECR framework, which measures two dimensions: how much you fear abandonment and how much you fear closeness itself.
Secure attachment means you're comfortable with intimacy and trust that others will show up for you. You can ask for what you need without collapsing if someone says no. You're about half the population. If you're securely attached, you're more likely to form relationships and sustain them, though you can still be single—by choice, timing, or circumstance.
Anxious attachment (sometimes called preoccupied) is characterized by a hunger for closeness mixed with fear that it will vanish. You're hypervigilant to signs of rejection. You might text too much too soon, ask repeatedly for reassurance, or stay too long in relationships that don't serve you because the thought of being alone is unbearable. You represent roughly a fifth of adults. Anxiously attached people often end up in relationships, but the relationships can be volatile or one-sided.
Avoidant attachment is the opposite: you value independence above all else. You're uncomfortable with emotional intimacy, even when you want a partnership. You might pull away when someone gets close, go quiet instead of arguing, or leave relationships that are getting serious. Around a quarter of people have this style. Avoidant attachment keeps you single more often, or single within a relationship—physically present but emotionally distant.
Fearful-avoidant attachment combines both fears: you want closeness intensely but expect to be hurt. You might pursue someone fiercely, then sabotage the connection. You're a small group—about five percent—but the pattern is exhausting. You often cycle between intense relationships and isolation.
Where your values enter the equation
Attachment style explains the how of your relationships. Your values explain the what and the who. You might have the secure attachment skills to form a healthy partnership, but if you haven't examined what matters to you, you'll end up with the wrong person. You might meet someone objectively suitable, but if your core values don't align, the relationship will slowly hollow out.
Values are what you actually prioritize, not what you think you should prioritize. If independence is genuinely central to how you want to live, a partner who needs constant togetherness will feel like a trap—not because you're avoidant, but because you're being honest. If deep emotional intimacy is non-negotiable for you, a partner who keeps you at arm's length will leave you starving, no matter how kind they are on the surface. Amir Levine and Rachel Heller's research in Attached shows that people who understand both their attachment style and their actual values make better choices about who to pursue and whether to stay.
You might be single because your attachment style makes you afraid of the vulnerability a real relationship requires. You might be single because you keep choosing people whose attachment styles clash with yours in ways that create friction. Or you might be single because you've been trying to force yourself to want things you don't actually want, waiting for a version of partnership that contradicts your real values.
What you can do about it
Attachment styles are not fixed. Bowlby's original insight, confirmed by decades of research, is that new relationships can rewire old patterns. You can move toward security through consistent experiences with someone trustworthy. But that requires knowing what you're actually looking for—and that's where values matter.
Start by noticing your own patterns. When you're in a relationship, do you become anxious and clingy? Do you withdraw and shut down? Do you sabotage? When you're single, are you actively avoiding dating, or are you looking but choosing unavailable people? These patterns point to your attachment style, and recognizing them is the first step to changing them.
Then ask yourself what you actually want from a partnership. Not what sounds good, not what your friends have, not what you think you're supposed to want. What does a life shared with someone else look like for you? How much time do you need alone? How much emotional expression do you need from a partner? What can't you compromise on? These are your values. When you're clear on them, you stop accepting relationships that don't fit. You also stop looking for people who can't give you what you need, which saves everyone time.
If you're single because your attachment style is keeping you stuck—because anxiety makes you pursue the wrong people, or avoidance makes you flee when things get real—that's changeable. It takes awareness, usually some difficult conversations, and the willingness to do things differently. If you're single because you haven't been honest about what you want, that's also changeable, and often simpler. The My Values attachment values assessment surfaces what your attachment patterns are and shows you whether you're living in alignment with your actual needs. That clarity is where real change begins.
Can attachment styles change?
Yes. Bowlby's work showed that attachment patterns formed early, but later relationships can shift them toward security. You won't rewire years of patterns overnight, but consistent experiences with a trustworthy, responsive partner change how you expect relationships to work. Therapy and self-awareness accelerate the process.
Does being anxiously attached mean you'll stay in unhealthy relationships?
It increases the risk. Anxious attachment creates fear of abandonment, which can make you accept poor treatment or overlook incompatibility. But awareness of your style gives you a choice. You can notice the anxiety rising and ask yourself whether you're staying because the relationship is right or because you're afraid to leave. That distinction matters.
Is being avoidant the same as not wanting a relationship?
No. Avoidantly attached people often want partnership, but they have genuine discomfort with the vulnerability and closeness it requires. They might prefer less frequent contact, more independence, or less emotional expression than their partners do. The goal isn't to become someone you're not, but to find a partner whose attachment needs are more compatible with yours.
Why do I keep ending up with the same kind of person?
Your attachment style acts like a filter. You're drawn to people who match your expectations of how relationships work, even if those expectations don't serve you well. Anxious people often pursue avoidant people, recreating familiar conflict patterns. Understanding your attachment style helps you recognize when you're being pulled toward someone familiar but wrong.
