Liberty Ross has spoken out for one of the first times since her estranged husband Rupert Sanders cheated on her with his “Snow White and the Huntsman” leading lady Kristen Stewart. The English actress, 35, has since set out to find herself and even posed nude for Love magazine after she filed for divorce from her director husband in January.

The public affair could have ruined Ross, but she told Vanity Fair for their December 2013 issue she is going through a rebirth. "It was horrible," Ross told the magazine. "It was really the worst, really the worst."

"I have no words to describe what we went through," she said. "But I think, for me, something always has to completely die for there to be a rebirth. And, for me, I feel like I'm going through a rebirth."

Sanders, 42, was photographed kissing Stewart, 23, on July 17, 2012, and the affair was exposed by multiple news agencies days later. Ross remained relatively silent after the cheating scandal went public, as did Robert Pattinson, Stewart’s famed "Twilight" ex-boyfriend whom she dated for nearly three years.

Sanders, like Stewart, released a public statement where he apologized to his then-wife and children. "I love them with all my heart," he said in the statement. "I am praying that we can get through this together."

But Ross said there wasn’t any way she should continue her marriage, despite never wanting to give up. "I'm not a quitter. I've done everything I could to be the perfect wife and mother and really support my husband," she told the magazine. "But I just didn't have any more to give, you know?"

Now, when Ross reflects on her marriage she admitted they weren’t perfect before the affair, that they had lost their “real connection,” and she forgives Sanders. "We were together for 16 years, and that in itself is really beautiful," she said. "And we've created two exceptional lives together."

They have two children together: daughter, Skyla; 7, and son, Tennyson; 5. The couple’s divorce has not yet been finalized. Ross’ interview with Vanity Fair will appear on stands nationwide on Monday.
