"I can't believe she is gone," Levine told People magazine
. "Mary was my life, my light, my love. The emptiness I feel without her with me is without bottom. She was a force of nature who fiercely defended her autonomy even as her health was failing."
He went on: "Mary was fearless, determined and willfull. If she felt strongly about something, or that there was truth to be told, she would do it, no matter the consequences."
Moore and Levine met in 1982 and were married the following November. Moore had been married to producer Richard Meeker from 1955 to 1961 and to the former NBC executive Grant Tinker from 1962 to 1981.
Levine remembered Moore as "kind, genuine, approachable, honest, and humble. And she had that smile. Oh, to see her smile that smile, just once more."
"My sadness is only tempered by the remarkable outpouring of good wishes, tributes, and personal 'Mary stories' told, with heart, by those touched by her grace," he said. "As long as we all remember her, talk about her, share our stories about her, and what she meant to us, her light will never go out."
