“Important people are sources of both pleasure and frustration. They may give us love, support, and even sexual satisfaction. So we love them. At the same time, they may express annoyance with us, criticize us, and frustrate us. So we hate them. This sad situation is inevitable, in the view of object relations theory. You cannot satisfy someone without also frustrating them sometimes. So love will never be completely unmixed with frustration and resentment. ”
