Final answer:
Lasting love does not depend solely on similarities; it includes factors of intimacy, passion, and commitment as outlined by Sternberg's consummate love, with relationships possibly thriving on complementary differences.
Step-by-step explanation:
I disagree with the statement that love is only lasting between like and like. Although similar interests and values can form a foundation for a relationship, consummate love, as defined by Sternberg, encompasses intimacy, passion, and commitment. Social exchange theory suggests that we may subconsciously weigh the benefits and costs when forming and maintaining relationships, but this does not necessarily mean similarity is a prerequisite for lasting love. Diverse relationships often thrive by complementing differences through mutual respect and understanding, leading to a strong bond that can also stand the test of time.
