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 between individuals, which can influence the likelihood of relationship formation. However, it is not an emotional component that grows within the relationship itself; rather, it is a situational factor that can facilitate the development of intimacy and other elements of love.

Passion encompasses the physical and sexual attraction in a romantic relationship. While it can be intense and significant, it does not necessarily deepen over time in the same way that intimacy does. Passion may fluctuate, often peaking early in a relationship before stabilizing or diminishing, rather than growing steadily.

Commitment involves the decision to maintain a relationship over time and to work through challenges together. Although it is essential for long-term relationships, it is more about the intention and decision-making aspect rather than the emotional closeness that intimacy represents.

Compassion is related to caring and empathy towards one another but is not specifically defined within Sternberg's triangular theory of love. It can enhance intimacy, but it does not directly represent the emotional growth aspect unique to romantic relationships.
