I agree with the above except I dont think she would have found anyone else. I think Rosalie was already at that point where she hated her life and was on the edge of breaking down before she found Emmett. Emmett was just a really rare breed of guy and the only one who could ever really understand Rosalie so I think if she didnt find him, she would eventually just give up and find a way to end her existence.
i agree this has nothing to do rose and emmet
and renemsee would have been born because edward would found bella regardless if rose didn't emmet
edward didn't like rose and he was ever attracted to her so u would ever have jake hot body it will always belong to renemsee which would be born so U GET OVER IT
I really dont think she would throw herself at Edward. She has way too much pride to do that and once she realized he wasnt interested she would react the same way she did at first.....she would hate him for resisting her.
