yea i've been wondering that cause one of the reasons bella wouldnt choose jacob over edward was because she would have ended up hurt like leah and she knew he would imprint someday but what if she did chose jacob then renesmee wouldnt exist and he would have never imprinted and idk its really confusing if you think about it
Up until the moment where Jacob saw Nessie for the first time and imprinted, I seriously thought he was going to end up with Leah. They just seemed to click, and could bond on a level that no one else understood. I'm also a bit of a romantic and I had this fantasy where Jacob and Leah fall in love and she's finally free of Sam. I REALLY liked Leah's character and I hate that Stephenie just kind of left her hanging. I thought it was all going to be good when she found her place in Jacob' pack, that she would finally be happy! and then it was...over.
Especially after they went into her character so much in the first half of BD, it was a shame that everyone else seemed to get a happily ever after, even Charlie and Sue, but Leah was just left there...
well i think if nessie wasnt born thats the way things would have went but nessie was born and the whole thing with the treaty and everything was resolved that wouldent have happened if jacob didnt imprint on nessie and plus right after nessie was born and roasalie was holding her and then jacob came downstairs wanting to kill nessie that would started a whole other conflict because jacob would still want to kill nessie so really the whole imprinting thing was sort of essential to bellas happyness and the happy ending at the end of the book yea it did suck that leah didnt get her happy ending but the whole series is about edward and bellas love not leahs issues
