The Amityville Horror star married Chilean film director Claudio Dabed in 2000, but they announced plans to divorce last year (11) and she went on to date music mogul Russell Simmons.
George has now revealed she gave her husband ""five years' notice on a couple of issues"" but felt she had to walk away when those problems remained unsolved.
She tells Australia's Herald Sun, ""It was something that happened pretty much overnight. I kind of gave him five years' notice on a couple of issues, and when it came up again for him, the lights just went out for me.
""I did have the best marriage. It was so full of love... But, at some point, when it stops serving your needs as a woman and the things that you want for your life, it's either get out now or wait until it's too late. It was very hard for me, but I'm glad I did it... I did the right thing. It was like an epiphany...""
George refuses to confirm the issues that led to the split, but hints her desire to have children may have played a part.
When asked about her plans for a baby, she adds, ""I wanted children, yes, but I still have time. Now I can start from scratch... (I think about becoming a mother) every minute of the day. Some days, it rips my heart out. And then, other days, I almost forget about it because I'm so busy... My acting is going great; I'm financially independent and I'm not short of love - it's not as if I'm sitting around at home, moping.
""But whoever I have my baby with, I want to be proud of that man and I want to carry a child to a man who wants to do that as well. But, hey, I've got years when you think about it.""
