Through the years, Wynonna has publicly shared her most painful struggles. "People walk up to me in airports and say, 'Why did you put your dirty laundry on Oprah?' I said, 'Because I want to be a teacher,'" she says. "I'm willing to teach through my mistakes and my victories."

Now, Wynonna hopes to help others by sharing how she survived an unimaginable betrayal. In 2007, Wynonna's then-husband, Daniel Roach, was convicted of attempted aggravated sexual battery against a minor.

Wynonna says she was in a public place when she first learned of Roach's arrest. "I'm literally in an airport on a golf cart, and people are pointing at me. 'Oh, she's the girl on the 5 o' clock news.'"
