What do you think of the ending of Stephenie Meyer's book Breaking Dawn?

The last book was sooo disappointing. The whole book wasn't that good and on some parts just didn't make sense. The book just didn't have a good story line and felt like some scenes Stephenie just threw in for fans. What i am talking about is the ending, i feel like after she had her baby they were building up suspense for this big fight scene with the volturi. We have to listen to Bella talk on and on how terrified she was, and they have half of the book to preparing for a fight scene. All of the other vampires come to back them up, Bella has a back up plan for Renesmee just in case they are killed, and i was expecting some excitement. Then they talk a little... decide not to fight.. the volturi go home... bella and edward have sex.. happily ever after, yea, done, the end!!? I get that its a Romance but that left me with my mouth open thinking wtf!!! I feel like this book went on and on with pointless chapters. Don't even get me started with the whole Jacob ending up with bella's baby, I think he should have been with Leah plus that was just weird and ewww. And Charlie would have freaked out about Jacob being a werewolf and Bella being a vampire but nooo he's all thats fine when can we have lunch!!!? Anyway sorry if i offended anyone but that's my opinion. What do you think about the book and its ending??
