Sexual infidelity is generally regarded as a grave symptom of a troubled relationship, and the revelation of an affair often triggers a crisis that threatens the entire foundation of trust and connection in a couple. In this workshop, we’ll discuss the complexities of marriage, sex, intimacy, and monogamy in couples from a multicultural, nonjudgmental perspective. We’ll explore the motivations behind affairs and their possible meanings in different relationships, both heterosexual and gay. We’ll examine the benefits and costs of truth-telling and transparency, how couples can rebuild trust and intimacy, and why affairs can actually stabilize a marriage. With an eye on the existential, clinical and ethical aspects involved, we will focus on how our own assumptions, values, and personal experiences can influence our therapeutic work and elude the needs of the couple. Combining didactic material, case studies, and video vignettes, we will lay out a nuanced therapeutic approach for working with extramarital relations, past and present, fantasized or real, disclosed or shrouded in secrecy.
