Guys, the books are actually really good if you know how to read them. Bella is not actually seeing and doing what she thinks she is. The entire story is far to ridiculous for that (a vampire that doesn't drink blood?) However, those who know older vampire stories will know that vampires have limited mind control over their victims. Bella is being mind controlled into thinking that Edward is the perfect boyfriend and that her real friend Jacob, an enemy of the vampires, is dangerous. Twilight is a tragic tale of deception from the point of view of a character that cannot even see the horrible fate she has fallen to. Bella's "decision" to become a vampire is a reflection on what one can be convinced they want to do. In the modern world of constant advertisement and branding, all can relate to being unsure of where their desires came from.
