What do you think renesmee will do when jacob dies because you know he can't live forever?

he can live forever. he doesn't have to but he can. i think.

If Nessie really loves Jacob then she might even sucide. Or might go into deppesion like Bella did when Edward left. If the eqution really is {Renesmee + Jacob = pag-ibig for them }then she will NOT be able to live without him.

I don't think he will die because there is no reason for him to give up changing into a werewolf. The Only way he can age is sa pamamagitan ng stopping changing and since Renesmee will live forever, he will choose to stay werewolf and not age with her.

I think Nessie will react like her mother but in a controlled way like her father. Sure, for the first few days she'd be awfully sad but she'll manage to ilipat on but will still pag-ibig Jake because she's part vamp, means things are permanent for her.

But I think Jake can live forever, all he has to do is not to stop phasing. he just has to keep on being a wolf, which is possible since he within vampire vicinity
