^ I kind of gave up on Twilight when the spoilers for Breaking Dawn came out but I keep coming back to J/B because they were the only good thing in the whole series.
As for Jacob making bad choices, I think due to his age and the fact that he has to deal with being a werewolf it caused him to do things impulsively without thinking of the consequences. It's not an excuse for the things he's done but it does make you think that maybe he was not in his right mind when he made those choices such as kissing Bella without permission.
I really love Taylor and Kristen's friendship as well, they're so cute
