These days, there are a lot of non-traditional ways to meet a potential partner. From dating apps to websites and even ... donating a liver?
For one newly engaged couple from Illinois, that's exactly what happened. Heather Krueger was diagnosed with Stage 4 liver disease in March 2014. Krueger's chances at surviving more than two months were put at 50 percent.
She was told she'd need to consider finding a donor as her condition continued to worsen.
Enter Chris Dempsey.
Dempsey, a former Marine, heard his co-worker — Krueger's cousin — discussing her medical condition. "When I heard about it, I just thought I would want someone to help me," Dempsey said.
"He called me and said the tests came out great, let's do this, I'm a match, I'm your donor," Krueger said. "I couldn't believe it."
In an eight-hour surgery, doctors gave Krueger 55 percent of Dempsey's liver. Then, during their two-month recovery in the same room, sparks began to fly. Just last month, Dempsey got on one knee and proposed in Chicago.
"You never know what will happen to change someone's life. I never would have thought this a year ago," Krueger told ABC News.
