The aria My Child from the opera La Callas ends the third scene.  Maria Callas and Aristotle Onassis have been together for several years years, but he wants her to stop singing because of the amount of time she devotes to preparing and performing.  Callas had always dreamt of being a mother, and being in her late thirties, she was willing to give up her career to fulfill that dream. However, Onassis had two teenage children and had no desire to start another family. As the scene ends, Maria Callas realizes that to stay with Ari Onassis, she will have to abandon her dream of being a mother. In this aria she sings of her sorry and grief to her child who can never be. She makes this sacrifice with complete conviction that the love between herself and Onassis is strong and that they will be together all their lives.
