How we cite our quotes:
I had to accept that I wouldn't see Edward again, not even one last glimpse of his face to carry with me to the mirror room. I was going to hurt him, and I couldn't say goodbye. I left the waves of torture wash over me, have their way for a time. Then I pushed them back, too, and went to face Alice. (21.80)
Bella feels that her greatest sacrifice is not giving up her life, but giving up being with Edward.
I stared at him uncomprehendingly. "But you'd be stuck inside all day in Florida. You'd only be able to come out at night, just like a real vampire." […]
[Edward:] "I would stay in Forks, Bella. Or somewhere like it," he explained. "Someplace where I couldn't hurt you anymore." (24.152, 154)
Once again, Edward is willing to sacrifice his happiness for Bella's safety.
