The need for love is deeply rooted in the human psyche(灵魂).     According to psychologists, separateness means to be cut off, helpless and alone in the world. It is the source of all anxiety.
   It can be selfish and possessive, or unselfish and giving. Abraham Maslow distinguishes between two kinds of love: B-love or “being love” means love for another person: unselfish love not dependent upon your own needs. D-love or “deficiency-love” is a selfish possessive love which is based upon someone else’s ability to satisfy your needs.
D-love is conditional. It depends upon whether personal needs continue to be met. But B-love is unconditional.     Furthermore, as it depends upon who you are, it is possible only when you allow yourself to be known to the other person.
The psychologist Erich Fromm also distinguished between two types of love.     Symbiotic union is an immature love based upon the satisfaction of needs and is similar to Maslow’s concept of D-love.
Mature love, on the other hand, is a relationship that allows individuals to retain(保持) their independence, their identity, and their integrity. In mature love people can overcome their sense of separateness yet continue to be themselves. The immature lover would say, “I love you because I need you,” but the mature one: “  ”
