213. Self-Expansion Theory: Do You Love Them, or Who You Become Around Them?
Have you ever met somebody and suddenly found yourself discovering new ideas, interests, ambitions or even entirely new parts of yourself? Perhaps you became fascinated by their profession, started seeing the world differently through their perspective, or felt unusually alive whenever you exchanged ideas.Now comes the provocative question: are you falling in love with the person, or with the expanded version of yourself that becomes possible around them?In this episode, Marie explores Self-Expansion Theory and its relationship with romantic attraction, sexual desire and our evolving sense of identity. We travel from relationships formed at work to relationships born entirely online, and even into the darker cyberpsychological territory of romance scams.And, Goddess, the central question remains yours to answer: when another human expands your world, when does fascination become genuine love?Share your opinion and personal experience through the contact form linked in the general podcast description. I would love to hear your perspective.REFERENCESAmerican Psychological Association (2026) PsycNet record 2026-63379-001.
