Bella has an obsession with Edward

[Susan]

Bella's only motive is Edward and there's not a single page when she isn't thinking about him. Of course she thinks of him, she loves him but it feels like he's the only thing on her mind. And he's her only motive to do things. She even wants to be turned into a vampire just to be with him. It's needed in romance for characters to think of each other but Bella takes it to an extream. She's not the only guilty one though. Edward watches her while she sleeps wich is a little creepy.
