British star Sienna Miller was destroyed when she discovered former boyfriend Jude Law cheated on her, because she had naively believed in true love. The FACTORY GIRL star had to endure a very public scandal in 2005 when her then-fiance admitted he'd had an affair with his children's nanny. She tells American publication Life, "What makes me sad (is) that there was a loss of innocence on my part. I was blinded by being a romantic person. "I sort of feel like, 'What if I never love that vulnerably and that openly again?' But I feel like I'm really strong. I feel like I grew up." Miller says the fact other women have faced the same situation helped her keep things in perspective adding, "People have made such a huge deal of it. "But every single woman I know has experienced the same thing - just not publicly. People would say, 'Poor her.' "But it wasn't the first time it's happened to me - and it won't be the last, I'm sure!"
