What term is used to describe the state of intense positive absorption typically present at the beginning of a romantic relationship?

The term that describes the state of intense positive absorption typically present at the beginning of a romantic relationship is passionate love. This type of love is characterized by feelings of excitement, attraction, and a deep emotional connection with one's partner. It often involves physical intimacy and a strong desire for closeness, which can create a sense of euphoria. This intensity can lead individuals to experience heightened emotions and think about their partner constantly, distinguishing passionate love from other forms of love that may develop later in a relationship, such as companionate love, which emphasizes deep affection and commitment over time rather than the initial fervor and infatuation.
