Triangular Theory of Love
Psychologist Robert Sternberg proposed a triangular theory suggesting that there are three components of love: intimacy, passion, and commitment. Different combinations of these three components result in different types of love. For example, a combination of intimacy and commitment results in compassionate love, while a combination of passion and intimacy leads to passionate love. According to Sternberg, relationships built on two or more elements are more enduring that those based upon a single component. Sternberg uses the term consummate love to describe a combination of intimacy, passion and commitment. While this type of love is the strongest and most enduring, Sternberg suggests that this type of love is rare.
