I, for one, am thrilled to pieces, and posit to you fine people a theory on why Bella and Edward have the most bland-ass, incomprehensible, "I NEED YOU TO LIVE" relationship ever.
It is thus:
Bella and Edward were brought together for no other reason than to birth Renesmee for Jacob. Who will probably end up leaving him anyway for that other half human/half vamp kid briefly mentioned at the end of Breaking Dawn, and someone needs to write THAT book because it already seems eons more interesting than Twilight.
So anyway the point is that there is absolutely no real basis for Bedward to be a "thing" other than cosmic forces pushing their junk together to create a kid for the dude who gets dumped on the whole time. And who is only driven mad by Bella's insane boringosity because of the unborn demon spawn in her belly.
My book was better. I want to read it again.
