A major period of upheaval in Bernstein's personal life began in 1976 when he decided that he could no longer conceal his homosexuality and he left his wife Felicia for a period to live with the musical director of the classical music radio station KKHI in San Francisco, Tom Cothran. The next year Felicia was diagnosed with lung cancer and eventually Bernstein moved back in with her and cared for her until she died on June 16, 1978. Bernstein is reported to have often spoken of his terrible guilt over his wife's death. Most biographies of Bernstein state that his lifestyle became more excessive and his personal behavior sometimes more reckless and crude after her death. However, his public standing and many of his close friendships appear to have remained unaffected, and he resumed his busy schedule of musical activity.
