It was reported last year that the couple, who had been together for three years, broke up after she caught him cheating.
"I just wanted to stop, I think it's called a nervous breakdown," she told the Sunday Times.
The 49-year-old said that she went off to Thailand to "heal" herself and was eventually thankful that the marriage didn't happen because "it wasn't the right union".
Despite getting engaged to the man 19 years her junior, Kylie also said in the interview:"'I've never been that woman, that girl who dreams of walking down the aisle."
The former 'Neighbours' soap opera star also said that she's accepts that she'll never have children.
