Often the fear of loss is more closely linked to a fear of being alone than commitment to a partner; in monogamous relationships, losing a partner means being alone. And, paradoxically, if you want something too badly, the fear of losing it can become greater than the joy of having it. When that happens, we hold onto things not because they make us happy, but because the thought of losing them makes us suffer. Both having them and not having them become sources of pain.
