One Tree Hill is coming to an end, and so is another romance from the set. Sophia Bush and her on-again-off-again boyfriend and co-star Austin Nichols are finished

31-year-old Austin is the third man she’s dated from the CW series. The reason for their split? “She didn’t think he was the one. She’s moving on”, one source told UsWeekly. Maybe Sophia only thought that with One Tree Hill coming to an end (the final episode airs April 4), she should be free to date one of her upcoming co-stars.
The actress has been already married to Chad Michael Murray in 2005. She also dated James Lafferty in 2009.
