“In the parking lot, he grabbed my hand and it was like a bolt of lighting went through me. Then he kissed me. My whole body melted,” she said. “I couldn’t believe this was happening. It felt good. We held hands in the car and looked at each other.”

If this seems a bit untraditional, just wait. There’s more.

A few important facts, aside from their 24-year age difference: Ms. Goldman has been married twice before; Mr. Corman once. She has two children from her first marriage; he has none. She lives in White Plains, about an hour on a good day from his Brooklyn Heights apartment, where he lives with a full-time aide. They intend to keep separate residences, because neither wants to move.

After their relationship took a romantic turn, they saw each other on and off over the next year. Ms. Goldman included him in the family holidays; he invited her to temple functions. Sleepovers became a regular occurrence as did monthlong jaunts to Florida.

In 2014, Mr. Corman proposed.

“We were sitting in my home having breakfast and Mannie said, ‘It would be wonderful for you to marry me. But you’d have to live in Brooklyn,’” Ms. Goldman said. “I couldn’t do that.”

“I have a life here. I babysit for my grandchildren. I have a lot of energy. Moving in with Mannie and leaving my home would be like cutting off part of my life. I told him, ‘I’ll change as a person and you won’t want me. I’ll be very different.’”
