Answer:
Social Exchange Theory
Explanation:
The Social Exchange Theory states that social behavior is the result of an exchange process in which the purpose is to maximize benefits and minimize costs.
According to this theory, people weigh the benefits and risks of the social relationship. If the risks are greater than the rewards, then the people terminate the relationship.
By writing a list of pros and cons about the relationship, Leland is weighing the benefits and risks of her relationship with Abbey and therefore this is explained better by the Social Exchange Theory.
