Well Bella is part of both of them... Bella likes 2 ride motorcycles and edward is so against it. she is like edward because they love each other plus jacob is like a daredevil an does pranks and he is a trouble maker so yeah umm that is why!
She only likes Edward because he's a vampire. Like it says in Eclipse.If vampires didn't exist Bella and jacob would have been together.I mean think about it.She's only drawn to him because of how cute he is wich is becuase he's a vamp. And Edward only likes her because she smells good. Jacob and Bella are meant to be.
