No fancy restaurants open, no Eiffel Tower backdrops? No problem.

Cupid is alive and well in the coronavirus quarantine, bringing couples closer together — for life. Proposals have gone off without a hitch during lockdown, even as some romancers had to switch gears from whirlwind proposals in Europe or celebrations surrounded by their nearest and dearest.

And, as it turns out, quarantining together has also made some couples realize they can’t live without each other. For some, it’s sparked spontaneous proposals these lovebirds will surely tell their grandkids about.

Here, six New York City couples share their unforgettable quarantine engagements.

Fox has been teaching Robinson how to play guitar on their balcony during isolation.

For Ilene Robinson and Allan Fox, the pandemic put their relationship into even sharper focus.

“This obviously hasn’t been an easy time, but we bring out the best in each other,” says Fox, 61, who has lived in Long Beach, LI, with Robinson for four years. “I wake up every day thinking, ‘I can’t believe how lucky I am to be with Ilene and look at what the world is going through.’ That was my impetus to take the plunge.”

On May 5, Fox, a singer-songwriter who works for the Legal Aid Society, woke up feeling especially romantic. During one of his balcony guitar lessons for her, he suddenly changed the lyrics of “I’ve Got You, Babe” to “Will you marry me?”

He dropped on one knee, as Robinson’s teen daughter was filming.

“I wasn’t even thinking about getting engaged … It was a ‘pandemic ring,’ as he calls it,” Robinson, a 55-year-old school teacher, says. “I wasn’t even thinking about getting engaged. We had talked about maybe one day [getting] married,” but she was still “completely shocked” when it happened.

Engagement agrees with the couple. “It does feel different,” Fox says. “We’ve woken up every morning thinking, ‘It’s fun being engaged.’ ”
