i think rose has been through a whole lot before she was transformed. and shes not mean, she knows what she wants and that for her family to be protected and bella has put rosalies family through alot of life threatening risks, and she doesnt understand how bella is willing to give up her life to be one of them, because rosalies life was about perfect when she was human and she would give anything to be human again, but she is stuck as a vampire and she has to live forever knowing nothing will ever change. i think she is very strong and independent and really pretty. Plus she's basically married to Emmet!! hello hes hot!
