The misguided application of Oedipal theory has led to the pathologizing of those with different gender identities or sexual preferences. Despite this harm, Oedipal dynamics are often viewed as a central organizing schema for understanding the dynamics of couples and families. In this paper, I revitalize Oedipal theory, divorcing it from its historical heterosexist bias, and highlighting its relevance for working with couple and family relationships, including LGBTQ and single parent households. Rather than using classical Freudian Oedipal theory which situates Oedipus in the psychosexual development of children, I use a contemporary Kleinian/Bionian model to orient the discussion to the relevance of Oedipal issues in adult relationships. Problematic Oedipal dynamics are not always present, but when they dominate or underlie adult relationships, they can be stifling, destabilizing, and destructive. This perspective emphasizes the importance of considering Oedipal triadic structures when working with diverse couples and families.
