“Marriage is not bliss. But it can be if you work at it,” the four-time Olympic gold medallist said. “A deal-breaker for me in a relationship is definitely loyalty. Well, not having it, that is.”

“Heartbreak is a part of life, whether it be a loved one, a boyfriend or an animal,” she continued. “But time heals all wounds.”
