Dubbed "the godmother of infidelity research," Dr. Shirley Glass reveals why affairs happen in good marriages. Endorsed by Oprah and praised by therapists, this revolutionary guide introduces the "windows and walls" concept that transformed how couples navigate trust and boundaries.
Shirley P. Glass, psychologist and groundbreaking infidelity expert, authored the seminal relationship guide Not "Just Friends": Protect Your Relationship From Infidelity and Heal the Trauma of Betrayal.
A licensed marriage and family therapist with a PhD from Catholic University, Glass spent decades researching extramarital relationships, pioneering insights that redefined modern understanding of marital betrayal. Her work revealed counterintuitive findings, such as many affairs arising from emotionally intimate workplace connections rather than marital dissatisfaction.
Dubbed the "godmother of infidelity research" by The New York Times, Glass appeared on Oprah, Good Morning America, and NPR’s Fresh Air while consulting for publications like USA Today and Newsweek.
A breast cancer survivor who treated couples in her Baltimore practice, Glass combined clinical research with compassionate pragmatism, emphasizing recovery over moral judgment. Not "Just Friends" remains a cornerstone in relationship therapy, cited by professionals worldwide for its actionable frameworks to rebuild trust.
Not Just Friends examines how platonic friendships can escalate into emotional or physical affairs, even in committed relationships. Shirley P. Glass identifies vulnerabilities in partnerships, explores the trauma of betrayal, and provides actionable strategies for rebuilding trust and intimacy after infidelity. The book emphasizes boundary-setting and transparent communication to prevent future breaches.
This book is essential for couples navigating post-affair recovery, individuals seeking to safeguard their relationships, or therapists advising clients on trust restoration. It’s also valuable for anyone interested in understanding the psychological roots of emotional infidelity and preventive measures.
Yes, it’s highly recommended for its evidence-based approach to healing after betrayal. Readers praise its compassionate tone, practical exercises (like the Fishbowl Technique), and realistic guidance for reconciliation. Many credit it with saving marriages by addressing both emotional and practical aspects of recovery.
Emotional affairs involve secrecy, deep emotional intimacy, and shared thoughts typically reserved for a partner. Glass warns these relationships often start innocently but erode marital trust and may escalate to physical infidelity. Key indicators include prioritizing the friend over the spouse and hiding interactions.
The myth assumes love alone prevents infidelity. Glass argues partners must actively maintain boundaries, avoid risky situations (e.g., private meetings with attractive colleagues), and openly discuss vulnerabilities. Proactive measures, not just trust, are critical for safeguarding relationships.
Glass advises couples to jointly envision future milestones (e.g., raising children, retirement) while honoring shared positive memories. She stresses consistency in transparency and patience, as trust rebuilds incrementally through repeated reliable actions.
Some readers note the book lacks faith-based perspectives for those seeking spiritual reconciliation. Others caution its intensive exercises may overwhelm couples in early crisis stages. However, most praise its balance of research and practicality.
Glass argues emotional affairs often cause deeper relational damage due to their secrecy and emotional substitution. While physical affairs may be situational, emotional infidelity involves redirecting intimacy needs to a third party, destabilizing the primary bond.
With rising workplace and digital interactions, the book’s emphasis on boundary-setting resonates in an era where platonic connections can easily cross lines. Its strategies help couples navigate co-ed friendships, social media, and remote work challenges.

What if your safest relationship became your greatest threat? One morning you're sharing coffee with your partner of twenty years. By evening, you've discovered they've been living a double life. This isn't a thriller plot-it's the reality facing countless couples today. Shirley P. Glass spent decades studying this devastating phenomenon, and what she discovered challenges everything we thought we knew about cheating. The most dangerous affairs don't start in bars or dating apps. They begin at the office coffee machine, in gym parking lots, through late-night work emails-innocent spaces where "just friends" gradually becomes something unrecognizable. Her research revealed a startling pattern: 82% of unfaithful partners had affairs with someone who started as merely a friend. This isn't your grandmother's infidelity. It's quieter, slower, and far more destructive because by the time anyone realizes what's happening, emotional roots have grown impossibly deep. Think about your closest work colleague or gym buddy. Now imagine that relationship gradually replacing your marriage as your primary emotional connection. This is how modern affairs unfold-not through dramatic passion but through incremental boundary erosions that feel harmless until they're not.
