Final answer:
Susan Hendrick identified six styles of love based on Robert Sternberg's triangular theory of love: liking, infatuation, empty love, romantic love, companionate love, and fatuous love.
Step-by-step explanation:
The styles of love proposed by Susan Hendrick are based on Robert Sternberg's triangular theory of love. According to this theory, there are three components of love: intimacy, passion, and commitment. Hendrick identified six styles of love by combining these components in different ways: liking (intimacy without passion or commitment), infatuation (passion without intimacy or commitment), empty love (commitment without intimacy or passion), romantic love (passion and intimacy without commitment), companionate love (intimacy and commitment without passion), and fatuous love (passion and commitment without intimacy).
