i believe that they will, i sure it wud be awkward that bella wud be jacobs mother in law but i do believe they will get married. I think stephenie meyer shud make a book about those 2 and how their lifes continue on after breaking dawn!
Honestly I think she will. She is growing up with Jacob around and as she matures she'll just grow to love him. It's fate really. I mean he did imprint on her after all. They were meant to be together.
I would love for them to get married! Nessie is a part of Bella and Jacob has always wanted to be with Bella and he would get to experience it though her. That would be great! I couldn't imagine Jacob with anyone else, just think if her and Jake had a baby it would be half vampire/human/wolf possibly!
