<h3>What is self-expansion theory?</h3>
Arthur Aron put forward the self-expansion idea, which is always applied to evaluate the upkeep of relationships, including familial, amicable, and amorous. In the context of relationships, "encompassing others in the self" is the primary method used by people to broaden their sense of self. Self-expansion is related to psychological concepts of self-efficacy, intrinsic motivation, self-actualization, and the self-improvement motivation since it is motivated by people's ability to achieve their goals. People in partnerships may feel far away and entirely distinct from the other person, or they may have psychological overlap, which is a strong sensation of oneness.
