This work, in collaboration with the students, outlines the relational sequence of couples from the earliest stages. It initially draws on the theory proposed by John Bowlby and the predominant attachment styles, exploring how these influence partner choices. It also references Murray Bowen (1991) and how levels of differentiation affect the choice of a partner. With this, we invite the reader to be critical of what they read, taking what is beneficial for their practice, expanding the knowledge that still needs to be gathered, and generating new learning in their daily journey. This work aims to provide an approach that allows the reader to have a kaleidoscopic view of the couple, its formation, its constant changes, its diversity, its final stage, and its encounter with challenges that lead to therapeutic consultation. It focuses on the meeting of two worlds, from the "I" to the "We," both in the couple and in the therapeutic relationship.
