WATCH Former First Lady Nancy Reagan's Legacy Remembered

Nancy Reagan, who died in her Los Angeles home on Sunday at the age of 94, was loyal to her husband President Ronald Reagan throughout their 52 years of marriage.

The former first lady, whose funeral service begins today, was remembered for the issues she championed, but perhaps her biggest legacy was her unbreakable love with Ronald.

James Rosebush, chief of staff to Nancy Reagan, said that the love the Reagans shared was real.

“I was often asked, ‘Is this genuine? Do they really have this kind of bond?’ and I said, ‘Oh yes, without question,’” Rosebush said on “Good Morning America.”

Their romance, which would span more than half a century, was captured by decades of love letters written by Ronald.

“My darling, I love you so very much," the president wrote to his wife on March 20, 1955. "I don't even mind that life made me wait so long to find you. The waiting only made the feeling sweeter."

Both actors, Nancy and Ronald's love began in Tinsel Town in the early 1950s.

The couple wed on March 4, 1952, in Los Angeles.

After they were married, Ronald continued his acting career, but Nancy retired to stay home with their two children, Patti and Ron Jr. and her two stepchildren Michael and Maureen, from President Reagan’s first marriage.

Nancy decided to became her husband’s devoted caretaker after he was diagnosed with Alzheimer’s disease. The only thing that could separate them was his death in 2004.

“I miss Ronnie a lot, an awful lot,” Nancy said of her husband in a 2009 interview with Vanity Fair magazine. “People say it gets better. No, it does not.”
