It is all right. When a person is unmarried he remains fresh. After marriage reality takes over, imagination is absent. Then, the partner becomes a possession, a part of one's self. Also, there may be fear of losing the person - though not in Hinduism, especially among Brahmins. Yet, tastes change. When a person is a child he may want a tricycle, then a bicycle. Later, that will have no meaning and he'll want a motorcycle. So it is with the mind
