I don't think so. I agree that, maybe, Jacob wanted Bella mostly out of competition with Edward, but Bella loved Jacob and although I don't like them together, I know that's true. Not just because she needed him. We can see that in Breaking Dawn, when she doesn't need him anymore, she still worries about him and loves him.
I think its the way its suppost to be! From the moment Edward and Bella laid eyes on each other, there was already something there! Jacob is an amazing guy but I think Bella belongs with Edward, I think it ended amazing! Everyone is still in each others lives and they became "friends". Bella made out...Shes with Edward, she has an amazingly special daughter, and Jacob (he best friend) is an active part of her life style!!
