Answer:
What best account for Marcia's feelings is that Passionate love has decreased, but Compassionate love has increased.
Explanation:
Passionate love can be described as a state of intense longing for union with another person. This type of love is more at the outset of a relationship. People in this state of love need to be near the other person, they may think about the other person constantly, and experience extreme distress when separated. It also includes an obsessive element, characterized by intrusive thinking, uncertainty, and mood swings. This type of love can work well at the beginning of relationships but can be hurtful in the long run.
Compassionate love is characterized by its level of intimacy. Also called companionate love, it is about intimacy, trust, commitment, and affection. In a long-term relationship, passionate love typically simmers down to compassionate love within one to two years.
People who are in compassionate love still feel passionate about one another, but the intensity typically feels less overwhelming and urgent. This type of love involves caring deeply for the other person, truly knowing the other individual, and is committed to the other person through both good times and bad.
