Love is one of the most profound emotions known to human beings. There are many kinds of love, but most people seek its expression in a romantic relationship with a compatible partner. For some, romantic relationships are the most meaningful element in their lives, providing a source of deep fulfillment. The ability to have a healthy, loving relationship is not innate. A great deal of evidence suggests that the ability to form a stable relationship begins in infancy, in a child's earliest experiences with a caregiver who reliably meets the infant's needs for food, care, protection, stimulation, and social contact. Those relationships are not destiny, but they appear to establish patterns of relating to others. Failed relationships happen for many reasons, and the failure of a relationship is often a source of great psychological anguish. Most of us have to work consciously to master the skills necessary to make them flourish. You can learn what you need to know to make your relationship last.
