As fate would have it, Moore’s mother Marge fell ill with severe bronchitis in 1982. The actress called her regular doctor, who was unavailable, and was instead connected with Dr. Levine, who was on call that day.

“After I’d seen her mom the second time, I said to Mary, ‘If there’s an emergency, just get in touch with me,’ " Levinetold PEOPLE in 1984of the serendipitous house call. “And Mary said, ‘Does acute loneliness count?’ And I said, ‘Yes.’ "

A few days later they made a dinner date. Soon enough, Moore and the Loyola-educated cardiologist, who was 15 years her junior and working at New York’s Mount Sinai Hospital at the time, began spending every weekend together.

“She fell really in love,” a friend of the actresstold PEOPLEat the time. “It’s been a real rebirth.”

Emanuel Azenberg, the producer ofWhose Life Is It Anyway?in which Moore starred on Broadway in 1980, called Levine “one of those doctors they wrote movies about 30 years ago.”

“He’s genuinely caring,” said Azenberg. “There’s no question they’re in love. They both have too much integrity to stay with the relationship if they weren’t.”

After filming two movies back-to-back that summer, Levine told PEOPLE Moore “had complained there were periods [during the day] when she just felt lousy.”

“It was I who said, ‘Hey, maybe the drinking is affecting your diabetes,’ " he recalled.

The cardiologist went on to perform a two-week study of the fluctuations in his wife’s blood chemistry, collecting blood specimens throughout the day and even waking her at night. He suggested that she cut out her after-dinner brandy and all other alcohol consumption for a trial period. Her blood chart steadied somewhat. His conclusion: Alcohol was affecting her body chemistry. It was not that she was drinking more — the problem was, “the disease is progressive and becomes more difficult to treat.”

“Everyone on the street thinks of Mary as being theirs. She’s at Betty Ford because her doctor and I thought she needed a supportive environment for abstinence,” Levine said. “Her goal is to gain some strength and understanding that it’s okay to say no to alcohol.”

“The first towns that realtors showed us things in were too close to the city, too suburban — because now we really wanted to be country. ‘Can we look a little farther north?’ we kept asking, ‘just a little farther north?’ " she continued. “And here we are. There’s not even a movie house in this town — you have to go to Poughkeepsie. Or do what we do on weekends, which is either go to bed early and forget about it or rent a movie.”

The widower shared how people may “think you know her and love her,” but how in reality they “don’t know everything.” Hedetailed some of Moore’s greatest struggles in life, including dealing with alcoholism while diabetic and the pressures of her dysfunctional family, while speaking to PEOPLE in May 2023.

Levine reminisced on how Moore had a strong passion for dance, even adding, “She said she would always believe herself to be a failed dancer as opposed to a successful actress.” He explained how she hoped that one day her dancing would earn her praise from her parents.

The cardiologist also shared that the one thing Moore kept private in their relationship was the death of her sonRichie, who died at 24 from a self-inflicted gunshot wound. She kept that tragedy “in a dark room. She didn’t want to touch that pain,” he said.

Levine also told PEOPLE that he considered it his role and privilege “to be her protector and care for her and hold her.”
