We have relationships with all those people with whom we are either connected by certain circumstances of birth or with whom we build an intimate bond with, at some later stage in life. Sad relationship is used to describe a relationship which lacks harmony and does not benefit either of the two people who are related to each other. According to Kristin Davis, “It's nice to be with someone, but I don't think you need to be in a relationship to feel complete. That would be really sad. “In a sad relationship, people related to each other stay sad and depressed. Happiness cannot exist in such a relationship. Fights, argument and heated discussions are a regular feature of a sad relationship. Sad relationship just brings sorrow and no happiness. Sad relationship is a relationship which completely lacks peace and harmony.
