Final answer:
Romantic love, as defined by Sternberg's triangular theory of love, consists of passion and intimacy but lacks commitment. It is a deep emotional and physical connection without the long-term promise.
Step-by-step explanation:
According to Robert Sternberg's triangular theory of love, the type of love characterized by passion and intimacy but no commitment is romantic love. Romantic love is marked by a strong physical and emotional connection between two people, yet it lacks the element of long-term commitment that might be found in other forms of love such as consummate love or companionate love. Passion refers to the physical attraction and romantic feelings, while intimacy refers to the closeness, connectedness, and emotional bond one may feel in a relationship.
While passionate love contains high levels of arousal and desire, it does not necessarily include the intimacy or deep affection found in romantic love. Companionate love, in contrast, includes deep affection and commitment but lacks the passion. Infatuation might be described as strong passion without the presence of intimacy or commitment.
