During the events of Eclipse, Edward choses to remain silent about his and Bella's engagement, and Jacob never threatens to kill himself to make Bella kiss him. So Bella never discovers her 'love' for Jacob so Bella and Edwards 'heartbreaks' are avoided. Plus, Jacob becomes the only casualty of the battle with the newborns. Bella is at first distraught but then internally rejoices that she is free from his intrusion at last. By the way, Bella and Edward do marry, they do have Renesmee, and Bella does discover her gifts because the events of Breaking Dawn continue just minus Jacob and thus the wolves. The Cullens gather an even larger group of witnesses to make up for the wolves. And the story finishes with Nahuel becoming the most likely candidate (in fact the only one) of being Bella and Edwards son-in-law.
