$79.95

Why do people have affairs — even in relationships that seem solid? What turns a harmless friendship into an emotional or physical betrayal?

In this powerful 90-minute webinar, Chris Cambas, MA, LMFT unpacks the groundbreaking research of the late Dr. Shirley Glass, author of Not Just Friends, whose work revolutionized our understanding of infidelity.

Glass taught us that most affairs don’t begin with sex — they begin with emotional openness, where there should be protective boundaries. In healthy relationships, partners build windows toward each other and walls around their connection. In unhealthy ones, those boundaries reverse — walls go up between partners and windows open to someone outside the relationship.

Walls, Windows, and the Real Causes of Affairs will help both couples and clinicians identify how and why those shifts happen — and how to rebuild transparency, trust, and connection after they do.

  •  Differentiate between emotional and physical affairs, including how emotional intimacy becomes the gateway to betrayal.
  •  Identify early warning signs of boundary drift, secrecy, and misplaced intimacy.
  •  Understand the psychological and biological underpinnings of attraction outside the primary relationship.
  •  Apply the principles of prevention and repair from Dr. Shirley Glass’s model in both personal and clinical contexts.

Who This Webinar Is For

This session is designed for both couples seeking to protect or repair their relationship and clinicians guiding clients through issues of betrayal, boundary confusion, and emotional drift.

For Couples

  • You’ve experienced a boundary breach or emotional betrayal and want to understand why it happened.
  • You’re ready to strengthen transparency and rebuild closeness.
  • You want to learn how to protect your relationship from emotional distance or outside intrusion.

For Therapists, Coaches, and Clinicians

  • You work with couples struggling with infidelity or emotional disengagement.
  • You want to use the “walls and windows” framework as a clinical assessment and intervention tool.

About the Presenter

Chris Cambas, MA, LMFT, is a Certified Gottman Therapist and co-founder of CoupleStrong and National Marriage Seminars of America. With over 20 years of experience in clinical practice, Chris has trained thousands of therapists and guided countless couples through the processes of betrayal recovery and relational renewal.

His expertise integrates attachment science, neuroscience, and the work of thought leaders like Shirley Glass, John Gottman, and Esther Perel — always with a focus on practical, compassionate repair.

Through his work, Chris helps both couples and clinicians move from reactivity to understanding, from secrecy to transparency, and from disconnection to authentic intimacy.

Why This Webinar Matters

Affairs don’t start in bedrooms — they start in conversations, text messages, and subtle shifts in emotional allegiance. When partners stop turning toward each other, they unknowingly open windows elsewhere.

This webinar explores:

  • How emotional intimacy outside the relationship quietly erodes safety.
  • The slow psychological slide from friendship to infidelity.
  • How to build walls that protect love — not imprison it.
  • The repair process that rebuilds integrity, accountability, and closeness.

You’ll walk away with both insight and tools to prevent, understand, and heal betrayal.
