idk man, every time I see a post about how jacob was better for bella, how he accepted and understood her exactly how she was, how he could have made her so happy... i don't know how to say "yes! this is totally correct! but also missing the whole point."
the fact that bella had another option for happiness (where she wouldn't have to sacrifice anything or change herself at all) but STILL CHOSE EDWARD ANYWAY is meant to lend more significance to her decision, not to demonstrate that she somehow chose incorrectly. bella knows she has the potential to become something greater than what she is by becoming a vampire. she also knows that SHE can't make JACOB happy because she will never stop thinking about what could have been with edward. and i think this was what stephenie was trying to say with the HEA in breaking dawn.
it's not that team jacob is wrong, it's that the whole jacob/bella relationship was designed specifically to be a tragedy. stories have themes – it's not just about rewarding whichever character is the least problematic. i agree that stephenie communicated this theme really poorly, but this is how i've always personally interpreted eclipse. jacob deserved better than what he got, but he also deserved better than being bella's second choice.
