I get what you guys are saying, and I think after a while [meaning years] after trying his hardest to get Bella back, he probably would eventually end up with Leah. After a long time, of course, I didn't mean that he would try for a short time, then quit.
I dont think that he would have got with Leah, or really anyone else. I think that if he didn't imprint with Renesmee that he would have gone off without the pack, or continued to try for Bella. Without Renesmee there would have been a different story for the 4th book all together.
well i think at first he would have still gone for Bella but by seeing how hurt he and Bella both get by this he would have left and after some months or a year he would have found someone and then that would be a happy ending for him. thanks for commenting =)
