Sophia Bush got to know herself better by dating the wrong guys.

The 'Chicago PD' star, who recently admitted her divorce from her former 'One Tree Hill' co-star Chad Michael Murray in 2005 after five months of marriage was ''unpleasant'' and they no longer speak following rumours he cheated on her with hotel heiress Paris Hilton, is currently dating Google program manager Dan Fredinburg but admitted she doesn't always have the best judgement when it comes her love life.

The 31-year-old actress told The Chicago Sun-Times' Splash magazine: ''I've dated a couple of the wrong guys, but I've also had great love in my life. I think every woman on Earth has dated the wrong guy at some point.''

The brunette beauty now knows what she wants and isn't afraid to discuss her relationships in public.

She said: ''At the end of the day, I'm an open book.''

She added: ''If I were looking at myself objectively, [I'd say] I'm a strong person and that can translate into a strong personality. I'll give all the space in the world to fairness, but I don't have any room for intolerance.''

Her passion for fairness has also inspired her to do more charity work.

She said: ''I have a lot of passion for society and how we should be treating each other. I'm a sucker for heroism.''
