While Jacob insists his feelings for Renesmee (Mackenzie Foy) will remain completely platonic until later in her life (as does Twilight author Stephenie Meyer), Bella (and most of the fandom) find their relationship to be unsettling at best.
Fans know, in the end, Jacob and Renesmee do live happily ever after together, along with Edward and Bella. Shoutout to Alice's future-telling skills! She gave viewers a glimpse of the future at the end of Breaking Dawn: Part 2.
Jacob was initially in love with Bella, but she chose Edward and gave birth to Renesmee, a half-human, half-vampire hybrid. As part of the imprinting, Jacob will only be a brother figure to Renesmee until she comes of age, by which time she may develop romantic feelings for him, and vice versa.
Jacob Black imprints on Renesmee Carlie Cullen, daughter of Bella Swan and Edward Cullen, upon birth in Book 2 of Breaking Dawn. Jacob was initially in love with Renesmee's mother, Bella; she eventually chose Edward over him, however, and mothered Renesmee—a vampire-human hybrid.
By imprinting on Renesmee, Jacob has imbued her with protection from other werewolves in his tribe. Prior to taking her on as a romantic partner, Jacob would first act as an older brother to Renesmee until she grew up – which won't take long given her hybrid nature, which makes her age more quickly.
So if freezing for a hybrid just means not aging anymore, then Renesmee could be perfectly capable of getting pregnant. The child would be half human, half vampire, and half wolf.
As a result, she not only gains immeasurable strength and good health, but her daughter, Renesmee, is born a vampire-human hybrid. Renesmee is special, because she is not an Immortal Child, or a child that was bitten by a vampire. Instead, Renesmee is born biologically.
Jacob has run away because he got that invite from Edward to the wedding. Bella chooses Edward, of course, and they get married. While on their honeymoon, Bella becomes pregnant.
Renesmee soon gave birth to twins Evan and Sarah Black a month later and another month after, Renesmee marries Jacob.
Jacob is extremely insecure and does a lot of abusive things to Bella. This isn't to say that Edward was a saint as he did some messed up things, too, but Jacob was often out of control. He would use his emotions to manipulate Bella to try to get her to be with him.
After Renesmee looked at Jacob in his eyes, he imprinted on her … but it doesn't necessarily mean that he fell in love with her while she was still a baby. Rather, Jacob's imprint on Renesmee created a bond between them that, hopefully, would be more protective than romantic.
Members of the Quileute wolf-pack do age if they do not phase for a long time; Jacob's body has physically grown to the equivalent of a 25-year-old in Breaking Dawn but stops aging after that. Jacob is the largest and strongest of the pack.
Yes. It's creepy as hell. Jacob is the same age as Renesmee's mother (in reality a year or two younger, but you get the drift). Biologically, he's seventeen to eighteen years older than Renesmee.
Did Jacob imprint on Bella? No. And this is how you can be sure: in New Moon, after the first time Jacob becomes his wolf phase, he is mean to Bella.
Renesmee is special, because she is not an Immortal Child, or a child that was bitten by a vampire. Instead, Renesmee is born biologically.
Bella chose Edward over Jacob because Edward associates more with Bella, is more similar to her, and appears to Bella as a better parent and provider. Edward and Bella are in closer proximity than Jacob and Bella because Edward and Bella go to school together.
The Jacob/Renesmee spin-off won't happen for awhile, as Stephenie Meyer is currently working on a Young Adult science fiction story.
Nahuel states that Renesmee will probably reach complete physical maturity around seven years after her birth, at which point she will stop aging and live to an unknown extent of years.
Bella gets pregnant after one night of passionate sex with her husband Edward the vampire, sex that leads to the destruction of their idyllic honeymoon suite.
In the world of Twilight, vampire women are unable to get pregnant because their body can not change to hold a fetus. But men are apparently able to get human women pregnant.
At the end of Eclipse, she becomes engaged to Edward Cullen, and they marry in Breaking Dawn, one month prior to her 19th birthday. On their honeymoon, she becomes pregnant, and, due to the peculiar nature of her baby, Bella nearly dies giving birth to their daughter, Renesmee.
By the end of Breaking Dawn, Jacob and Bella finally put their issues behind them and become best friends once again, with Bella accepting him as her future son-in-law.
Seeing as she's half vampire, one would think she would age much slower than humans, since vampires can't age at all. However, poor unloved Jacob shouldn't have to wait eighteen years for his happily ever after, so Renesmee grows abnormally fast, and will magically stop aging once she reaches sexual maturity.
However, as a half immortal, she will continue to grow until her full maturity at the age of about seven, at which point she will appear to be about seventeen (like her father Edward) and will cease to age (as shown by Nahuel in Breaking Dawn).

Edward reads Renesmee's mind. Edward hears inappropriate thoughts from Mike Newton about Bella and discovers Jacob's appearance using mind reading to pick up his mind.
