Although i like Bella the most when she's a vampire. I think it was a bit irrational just leaving all her friends (and Charlie), basically her whole life to be with Edward.(And i mean before she had Renesmee, of course she would have to after her birth, otherwise she would die. DOI lol) You do some crazy things for love, but that's waaaaay extreme.
I just hope that the younger audience that's reading the books don't automatically think it's a good idea to focus there whole life to finding there 'Edward'. Tis' not the best influence. But that's probably just me being picky :)
If i were her i would have picked Jacob. As for immortality or to stay mortal i would love to be an immortal... i hate being human!! i would love to be a vampire or a werewolf.
