What is Rosaline Hale personaty?

Rosalie's personality is that of a very vain person. She's beautiful and described by Edward as pigheaded. In Twilight, she thinks Bella is a threat to the secrecy of her family and that she can't be trusted, and she doesn't want to help them fight off James to save Bella's life. In New Moon, she's the one who mistakenly tells Edward that Bella is dead, causing him to go to the Volturi. In Eclipse, Rosalie tells Bella about her feelings toward her and why Rosalie voted against Bella's immortality. She says that, even though she only thinks of Edward as a brother, she was jealous of her that Edward was so attracted to Bella, even though he never shows any affection towards Rosalie. It bothered her because she was so used to attention and men's affection toward her. Rosalie apoligizes to Bella for being rude, and they seem to be on the right track towards friendship. In Breaking Dawn, Bella asks for Rosalie's help with her pregnancy and she agrees, though when the Cullens find out that Bella is dying, Rosalie tells her to stay alive to have the baby so that Rosalie can have it for herself. She doesn't care whether Bella stays alive or not, so long as she can care for and mother Bella's baby because Rosalie would trade anything, even Emmett, to be a human again and have a baby.
