To me the worst book in the saga is Breaking Dawn, I actually never read it until about 4 months ago while I was at a friend's house and we were feeling a lack of “closure” towards the saga because we never read the last book (cause we heard it sucked) so we decided to head to Barnes and Noble and buy two copies.
Big mistake.
Although I enjoyed learning about what happened after Eclipse I couldn't help but feel dissapointed about the new central character to the book….Renesmee…the way Bella glorified this “child” and was so crazy about it and about protecting it even if it meant the end of her own life was a big let down for me.
I think we all fell in love with the books because of the characters, mainly Bella and Edward as a couple that to bring someone else into it was just a recipe for disaster.
The way this “child” had taken over the whole family AND Jacob was irritating and it made it feel like Edward and Bella weren't important anymore now it was aaaaall about Renesmee. Kind of like some parents are about their kids where they can't talk about any subject other than their children, almost as if they didn't have children they wouldn't have a personality or anything to talk about.
This book made me look at Edward and Bella in a different light. Made me wish the story was still about their love and about Bella's new life as a vampire. I think their “child” should have stayed out of the picture.
Bella and Edward's relationship was great without it, more interesting, more intriguing, more exciting,more relateable, more about them two.
And as we all know….
If It Ain't Broke Don't Fix It
just my thoughts

Especially after the encounter with Laurent and her not yet figuring out about the wolves: she feels like she's unnecessarily endangering Jacob (on top of her other loved ones, her family), that it would be in his best interest to cut off the whole friendship/romancing stuff. Feeling extremely (overly) responsible for it, as if she was leading him on, putting a spell on him, while Jacob inquired about her feelings very directly at the cinema – and thus taking his own part in staying close to her despite her official rejection.
And then there were all those analogies about Jacob being her sedative, her addiction, her drug – just like Edward called Bella his personal brand of heroin in Twilight… Both Edward and Bella (then and now) are trying to quench a thirst, a craving, a natural drive to stay 'alive'.

In addition to her own ever continuing draw towards Edward, I think, unconsciously and especially through his current absence, she's learning an invaluable amount more about Edwards' character and his take on 'life', be it alive or 'undead'. It all started with Carlisle's explanation on Edward's 'soullessness'-theory, just before his leaving.
