yeah i think they would but not till later on....if Bella was willing to let Jacob take Nessie then she would understand that the love they will have later isnt something that could ever be broken. And that Jacob really is looking out for Nessie best interest.
Of course they will. It would be odd if they didn't. Bella always wanted Jacob in her family and Edward told Jacob in BD that he considered him like a brother. I always figured they'd get married when she got older. I just hope one day Steph writes about Renesmee and Jacob's developing romance.
Bella and Edward may not have been happy when Jacob in printed on Ness. I believed that by the time that Ness has grown up they will remain very close friends, but eventually will get married. I believe that Bella and Edward will eventually approve of the marriage, as they would know that Jacob would do anything for her to keep her happy and safe.
