[Bella to Edward:] "Which is tempting you more? My blood or my body?" I challenged. [Edward:] "It’s a tie." (2.230-231)
Bella wonders how much of Edward is man and how much of him is vampire in his attraction to her. You could take this a step further and wonder if Edward would still be attracted to Bella if she were a vampire as well. What do you think?
[Bella:] "You… don’t… want me?" I tried out the words, confused by the way they sounded. (3.172)
There’s an entire world of meaning attached to these four simple words and Bella’s mind struggles to make that connection just yet.
Love, life, meaning… over. (3.214)
Without Edward, Bella sees no meaning in her existence.
