I grew up Mormon, and I can tell you that from a young age, it is impressioned upon young girls that they need a man to take care of them, and teach them to be a housewife only. Not that a career is not allowed, but it is subliminally discouraged, as the roll of women in the Mormon church is to simply breed more tithe payers.So you can understand the underlying analogy in Twilight that Bella is a sad and helpless girl without a man to be her superior and tell her how to live. She goes ***** insane just because Edward leaves her, and she can't function without a man to give meaning to her life.
