Final answer:
Sternberg emphasizes that compatible love stories are essential for a happy and healthy love relationship, aligning with his Triangular Theory of Love that includes intimacy, passion, and commitment.
Step-by-step explanation:
According to Sternberg, the key to a happy, healthy love relationship is that both partners have compatible love stories. This concept falls in line with Sternberg's Triangular Theory of Love, which posits that a happy and healthy love relationship encompasses intimacy, passion, and commitment, culminating in what Sternberg calls consummate love. Contrary to focusing on factors such as good paying jobs, college education, or the same religious beliefs, Sternberg emphasizes the psychological and emotional dimensions of love that create a balanced and fulfilling bond. This understanding of love illustrates that healthy relationships are based on a deep connection and shared narratives rather than just external factors or similar backgrounds.
