Jacob likes Renesmee because he imprinted on her.
he becames attached to renesmee it is like it OS not gravity holding him on earth but renesmee instead
In the firts two parts of Breaking Dawn Jacob still is "inlove" with Bella. During the third part Jacob imprints, or falls inlove, with Bella and Edward's daughter, Renesmee.
I Breaking Dawn, Renesmee has an unusual power to comunicate by touching you. Jacob imprints on her and a while after that, Irina (Laurent's mate) saw Renesmee and she looked like an immortal child so she went and reported them to the Volturi.
The main characters in Breaking Dawn are Bella Edward and Renesmee. REnesmee is a new character and she is the daughter of Edward and Bella. She is half human and half vampire. Also I guess Jacob is a good charector. Jacob imprints on Renesmee. Imprints, meaning He would marry her and no one else!
Jacob imprints on Bella and Edward's daughter, Renesmee. Imprinting means that Jacob is now "tied" to Renesmee; in other words, he is in love with her. Even though she is so much younger, he now feels like her big brother and when she's his age, they'll be in love. Jacob is dedicated strongly to Renesmee, and it's just a "wolf thing" that can't be controlled. Jacob did not choose to imprint on Renesmee, it just happened.
Bella does love Jacob but she loves edward more but in breaking dawn when Bella knew that Jacob tricked her into kissing him in eclipse she started not to like him and she knew that he loved renesmee but she knew that Jacob still cared for Bella
One simile I found in breaking dawn is when bella finds out jacob imprinted on renesmee. Staring at her like he was a blind man seeing the sun for the very first time. (page 448, 3rd paragraph).
Yes, while she is growing up he acts a brother, and then a friend until she reaches his age then they have a physical, real relationship.
No, at the start in twilight, Rosalie didn't like Bella and they only started to actually become friends in Breaking Dawn when she's about to have Renesmee, Jacob and Edward do not like each other and only become nice to each other at the end of Breaking Dawn. but everyone else always likes each other. (if that makes sense)
I don't think they've gotten that far.
In Eclipse, she figures out for herself that she is in love with Jacob as well as Edward. But she gets married to Edward in Breaking Dawn.
In a human world yes. But Jacob doesn't age as he is a werewolf- remember the growth spurt he had? Technically he's about 26 but he isn't getting any older and while Renesmee is growing up, he acts more like a brother and a friend to her than a lover.
