Final answer:
A romantic relationship will typically decrease in passion, while it either becomes more committed or ends. Factors such as life stages, technology, and societal pressures can significantly affect the trajectory of the relationship.
Step-by-step explanation:
Over time, a romantic relationship will typically decrease in passion while either increasing in commitment or ending. During adolescence, romantic relationships commonly begin, and they can evolve significantly through the life stages of the individuals involved. Sternberg's Triangular Theory of Love indicates that different components of love, such as intimacy, passion, and commitment are important, but these elements might not all be present in equal measure throughout the life of a relationship. Age-gap relationships, the use of technology such as messaging, and societal changes all influence the dynamics of romantic relationships, which can result either in increasing commitment -- akin to getting married -- or in dissolution -- similar to getting divorced.
