Jason Alexander shared one of the most important lessons he's learned from his relationship with wife Daena Title.

The 65-year-old alum married Title, 68, in 1982. More than 40 years later, he was asked about the secret to their long-lasting romance during a Monday, March 10 appearance on the Today show.

"I'm married to a woman who lives this thing that I first heard of in A Raisin of the Sun. It's kind of quoted there, but she does it. It goes something like this: On my worst day, she remembers me on my best day and beckons me back," he said.

Alexander continued, saying, "If you have a partner who can do that, because we all have worst days, you don't give up on that partner."

"I am a lucky man," he gushed.

The couple met in the early '80s and welcomed their sons Gabe and Noah in the '90s. Their family expanded again more recently when Gabe welcomed his first child, making his parents grandparents.

Alexander and Title's love story is a passionate one. The actor said that he and his wife started living together three weeks after their first date. Marriage followed shortly after.
