i dont know i just dont see her with anyone else
well. i think renesmee and jacob would turn out to be a perfect couple but i'm thinking that.. how could they stand their scents right? so i also think that leah and jacob should be together.
Jake and Leah would have been great, they both lost a loved one (Jake > Bella, and Leah > Sam) to another person, that other person's true love. During breaking dawn I completely began to stop shipping (supporting the couple) that was formally my favorite BlackSwan (Jacob and Bella) and started shipping Blackwater (Jacob and Leah), their bond grows so strong in such a short period of time that its quite astonishing really. And I personally just dislike Nessie. She's quite annoying as she's smart enough to know that she's all high and mighty, I would have preferred Seth imprint on Nessie because Seth seems to be the type of guy who already understood and loved vampires, he accepted them, and it would have made more since for him to be the one that completely accepted Renesme.
Thats just me ^^
