Final answer:
Uncoupling in a relationship is complete when the two individuals involved have fully separated their lives, which can happen after going through different stages of emotional and legal separation. The process is akin to breaking and forming bonds, where at the final stage, individuals no longer see staying married as favorable to their well-being.
Step-by-step explanation:
Vaughan asserts that uncoupling in a relationship is complete when the two individuals have reached a point where their lives are entirely separate. In the context of marriage and divorce, this could mean a range of things, from the emotional detachment to the physical and legal dissolution of the marriage. Uncoupling is a process that often involves stages, starting with a secret dissatisfaction, moving to a public acknowledgement of the problems, and finally culminating in the separation of lives. This could also be reflected in the changing perspectives of the individuals about the relationship and their readiness to start anew.
The statement 'The breakage and formation of bonds is similar to a relationship: you can either get married or divorced and it is more favorable to be married' aligns with the idea that, in many cases, maintaining a marriage is seen as more desirable or 'favorable'. However, when uncoupling is complete, individuals are presumed to have moved past this stage and no longer view the maintenance of the partnership as favorable to their circumstances or happiness.
