How we cite our quotes:
[Charlie:] "He's too old for you," he ranted. (17.114)
Dads can sometimes disagree with their daughters on whom they should date. Little does Charlie know 1) how "too old" for Bella Edward really is, and 2) the other things about Edward that he should be concerned about.
[Bella to Charlie:] "I'm going home," I shouted, my voice breaking in the perfect spot. (19.20)
Bella lies to her dad in order to save his life. She realizes that Forks is now more of a home to her than Phoenix, but she's determined to leave if it means protecting Charlie.
[Bella to Charlie:] "I do like him – that's the problem. I can't do this anymore! I can't put down any more roots here! I don't want to end up trapped in this stupid, boring town like Mom! I'm not going to make the same mistake she did. I hate it – I can't stay here another minute!" (19.33)
Bella is lying to her father when she says that Forks cannot be her home. She uses the same cruel words her mother had used when she left... that's a low blow. However, Bella is willing to hurt Charlie because she believes that it will save him from James. Charlie's safety is the most important thing to her right now.
