"But I thought it'd be cheesy to do it overseas," he said.
Instead, he picked a park that they had frequented many times throughout their relationship -- Letchworth State Park in Castile, New York.
"It's just in our home town so we have a lot of history there," Ragatuso explained.
The two high school sweethearts reunited back in 2004 after splitting up. In fact, it was after Ragatuso was diagnosed with a heart condition that he decided to reach back out to his high school girlfriend, who had made a career as a nurse practitioner in cardiology.
Ragatuso admitted that he didn't know exactly where in the park he wanted to get down on one knee last Sunday.
"But when I looked up, I saw we had a good backdrop. I told her that we were going to take some pictures," he detailed. But instead, Ragatuso started a video to capture the heartwarming moment.
"I was absolutely shocked when I turned around and he was down on one knee," Fahey, 31, said. "Never did I think it would end up being the most meaningful moment of our lives."
A video of that moment has gone viral on Instagram, with more than 32,000 views.
