How we cite our quotes:
[Edward to Bella:] "I brought you to the prom," he said slowly, finally answering my question, "because I don't want you to miss anything. I don't want my presence to take anything away from you, if I can help it. I want you to be human. I want your life to continue as it would have if I'd died in nineteen-eighteen like I should have." (Epilogue.156)
Edward has a different life philosophy than Bella. He wants her to enjoy her average, human life and not miss anything.
