I want to be sure I understand correctly. Jacob professes his love for Bellas baby. He envision her as his lover once she gets older yet she is a baby. He is her protector/best friend. Now from a realistic point of view I can see the pedophilia tendencies. Now from a fictional point of view, I still see pedophilia tendencies. Note: not all pedophiles have relations with kids. Many fantasize.
Feel free to elaborate for me if my interpretation is a bit skewed.
