Actress Liberty Ross says she went through a horrible time after discovering that her now estranged husband Rupert Sanders cheated on her with Kristen Stewart.
The news emerged last year in June when Sanders was caught getting intimate with Stewart.
Ross finally ended her 16-year-long marriage after realising that she has nothing more to invest in the marriage, reports dailystar.co.uk.
"It was horrible. It was really the worst, really the worst," Vanity Fair magazine quoted Ross as saying.
"I'm not a quitter. I've done everything I could to be the perfect wife and mother and really support my husband. But I just didn't have any more to give, you know," she added.
Ross has two children Skyla and Tennyson with Sanders.
