After actually having seen the movie now...I guess Jacob treats her a little better, although once he actually becomes a werewolf he tries to shoo Bella away just like Edward did.
Although having seen her best choice of the humans, Mike, the whiny, third rate Shia LeBuef, who pusses out and throws up at action movies, I kind of understand her willing to put up with dealing with someone who may or may not rip her face off at any moment.
