A Czech relationship therapist, Martin Galbavý, discusses evolving definitions of infidelity in the digital age. The conversation highlights phenomena like “just texting” others, seeking emotional connection outside of primary relationships, and forming intimate bonds with artificial intelligence. These modern expressions of infidelity, termed “micro-cheating,” operate on the same core psychological mechanisms as traditional cheating. Galbavý emphasizes that choosing a partner inherently involves forgoing other potential connections. The discussion explores how new technologies and communication methods are reshaping the landscape of relationships and challenging conventional understandings of faithfulness. The core issue remains the emotional investment and boundaries within a committed partnership.
