why doesnt jacob imprints on bella but he imprints on renesmee[dont think i spelled it right srry]

They dont choose who they imprint on, its like Fate. The person your meant to be with, with stronger bond than 'just love'. They know once they meet them <3

because bella is not the right person for him and shes in upendo with edward.

he can't choose who he imprints on, thats the whole problem lol

just because he loves bella doesnt mean he'd imprint on her...just like sam and leah, they were in upendo until he found emily. The wolfs imprint on someone who is most likely going to carry on the mbwa mwitu gene and be a strong genetic match. Renesmee is half human half vampire, which means if her and jacob had babies they would be 1/3 human, 1/3 mbwa mwitu and 1/3 vampire. They would be shapeshifter like their dad but they would have vampire qualities- such as inpentrable skin, speed and extra strength- making them pretty much invincable i.e renesmee would produce the best offspring with the best genes

He doesnt have control who he imprints on...just like Sam and Leah..Sam thought he was in upendo with Leah until he saw Emily...and *boom* the imprinting happened. It has something to do with 'soulmates' and making the bloodline stronger for the future wolves.
