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.
