According to Robert Sternberg's triangular theory of love, which aspect of love is the emotional component that grows over the course of a romantic relationship?

Proximity refers to the physical closeness or geographical nearness of individuals, which can facilitate the formation of relationships but does not inherently reflect emotional depth or growth. While being near someone can lead to increased interactions, it does not equate to or signify the emotional development that occurs in romantic relationships.

Passion involves the intense feelings of attraction and sexual desire that can be present in relationships, especially in their early stages. However, while passion can be an initial driving force in a romantic relationship, it does not necessarily develop or deepen over time in the same way that intimacy does, often fluctuating instead of growing consistently.

Commitment refers to the decision to maintain a relationship and the intention to stay together despite challenges. Although commitment is crucial for the longevity of love, it is more about the decision-making aspect of a relationship rather than the emotional connection that evolves through shared experiences.

Compassion involves empathy and concern for a partner's well-being, which is important in a relationship. However, it is not one of the foundational components in Sternberg's triangular theory, and while it may be present, it does not specifically address the emotional growth aspect that intimacy encapsulates.
