By Certified Emotionally Focused Couples Therapist and Supervisor Stephanie Cox, MS, LMHC. Published by the American Counseling Association with a projected Release Date in 2027
Adult friendships aren’t supposed to feel fragile, but for many, they do. Messages go unanswered, group chats fade, and one-sided dynamics quietly take hold. If you’ve ever wondered why this keeps happening—and why quick fixes don’t last—you’re not alone.
Friendless: Why Adult Friendships Keep Failing moves beyond surface advice to explore the deeper patterns shaping our closest connections. Drawing on attachment theory and relational research, Stephanie Cox introduces the concept of a Secure Base of Friendship, a framework for building relationships that are mutual, stable, and sustaining.
Through relatable case examples and practical tools including the Seven-Step Secure Friendship Arc, readers learn to navigate common challenges like life-stage mismatches, toxic patterns, conflict, repair, and letting go.
At a time of rising loneliness, Friendless offers something rare: a grounded, compassionate guide to understanding why friendships falter and how to build ones that truly last.

This is a clinician guide—meaning therapists will get a clear framework and tools you can actually use in sessions (and assign as homework).
And it’s written in a way that non-therapists can benefit from immediately, because it’s not therapy-speak. It’s real-life language for real-life friendship pain.
Therapists: use it for conceptualization, interventions, scripts, and repair work for your lonely clients.
Everyone else: use it to stop guessing and start building friendships that feel mutual and steady.
Most of us learned how to navigate friendship by just figuring it out as we went. No one handed us a roadmap. So it's no surprise that patterns formed along the way — ways of showing up that feel completely normal to us, even when they're quietly getting in the way of the connections we actually want. The "Am I a Secure Base Friend?" quiz will help you identify your friendship type, understand how you're showing up, and what it means for the relationships you're building.
