Couple’s therapy can be 90% preparation, and 10% action. Be 100% prepared  to start with this bundle. Relationships between couples contain unique problems that individuals could never know. Treating one person is complicated, but the relationship between romantic partners introduces complexity. Enabling couples to find simpler solutions will require the couple’s starter kit to understand their world. Working with their ecosystem includes understanding elements instrumental to their success; boundaries, sexuality, intimacy, power differentials, and general systems theory are a foundation for any clinician’s interest in treating relationships.
