Every one seems to miss the point that Edward is a genetically perfect predator - OF HUMANS. He is designed to be OVERWHELMINGLY attractive to his prey through physical beauty, pheromones, mannerisms etc. When Edward turned his attention t Boellato Bella she never had a choice. There was no exercise of free will. She did NOT fall in love, she became addicted, obsessed. Her reaction to his departure in New Moon was a pretty good description of withdrawal from drugs. This should give an indication of just how strong her feelings for Jacob grew, that she developed them even in the cru}{ciblecrucible of her obsessive feelings for Edward. If Edward had stayed away a bit longer allowing Bella to finish healing and a bit more time for the relationship with Jacob to grow, I think Bella would have easily chosen Jacob.
