In Breaking Dawn, Bella becomes vampire, she can't sleep. U think she'll be bored with time. She'll be with Edward forever doing the same things again & again....

I would be bored. Living forever. BUT...

She's living with Edward for forever. That's the whole point isn't it? She chose him. He's who she can't live without. And with him, comes being a vampire, which comes with forever. That's what she's wanted throughout the entire series.

I don't think she'll get bored. She had 3 पुस्तकें to chose her decision and she finally made her decision in Eclipse: to be with Edward... for eternity. I think she thought it through pretty thoroughly wouldn't you?
