Ryan Reynolds recently ended his brief romance with Charlize Theron as Contactmusic.com reported yesterday, and now the reasons why he made the decision are starting to emerge. A source told US Weekly magazine: "He only wanted something casual, but she's in a rush to settle down, have kids and start a family since she's getting older." The source added that Charlize 'didn't take it very well when he broke it off. She knows deep down that it wouldn't have worked, but she is pretty bummed out about it all."

Reynolds split from wife Scarlett Johansson in December, and Theron recently broke up with Stuart Townsend after dating him for nine years. Reynolds and Theron were only together for two months until Reynolds broke it off in late July, the Daily Mail reported, and they had managed to stay off the radar until Theron was spotted leaving Reynolds' Malibu home. They were set up by mutual friends and had been neighbours for years, but Theron's urgency to start a family coupled with busy schedules meant that the romance was never going to last. The US Weekly source continued: "They're both too busy and they were hardly ever together anyway."
