Kim Carpenter has admitted the affair that ended his 25-year marriage to his wife, Krickitt.
"I owned it, I took responsibility for it," he told Inside Edition.
Their incredible love story was the basis for the hit 2012 movie, "The Vow," which starred Channing Tatum and Rachel McAdams.
Kim and Krickitt married in a lavish wedding in 1993. Two months later, they were in a horrific car accident. She suffered a brain injury and was in a coma for three weeks. When she woke up, she had no memory of her husband.
Slowly, Krickitt fell in love with her husband again, and they renewed their vows in 1996. They later had two children.
But the romance regarded as one of the greatest love stories ever told has now crumbled after Kim admitted he had strayed from the marriage when confronted by his wife.
“The fact that you spend years and years combating and fighting for something that you are committed to and to go out and do the inexcusable was not," he told Inside Edition.
"It was just a very unfortunate situation."
After he confessed to Krickitt, there was heartache.
"I was beyond devastated because I never would've imagined that would happen to me and I experienced the most excruciating pain that I’ve ever felt," she said.
"The thing that really hurt me the most was the shock I had of how upset she was," he added.
Now that the divorce is final, Kim is trying to move on. She is living with their daughter, LeeAnn. He is living with their son, Danny.
“I’ll forever feel in my character the guilt and shame that I have," he said.
