Integrating
In the integrating stage, two people’s identities and personalities merge, and a sense of interdependence develops. Even though this stage is most evident in romantic relationships, there are elements that appear in other relationship forms. Some verbal and nonverbal signals of the integrating stage are when the social networks of two people merge; those outside the relationship begin to refer to or treat the relational partners as if they were one person (e.g., always referring to them together—“Let’s invite Olaf and Bettina”); or the relational partners present themselves as one unit (e.g., both signing and sending one holiday card or opening a joint bank account). Even as two people integrate, they likely maintain some sense of self by spending time with friends and family separately, which helps balance their needs for independence and connection.
