Do you think Bella would leave Edward if Jacob imprinted on her???

Even as human or vampire, i don't think she would give up on her family (the cullens), it's not because jake imprinted on her, that she is in love with him (she is, but she loves edward more) and that they should be together.
Edward is and shall always be bella's true love, the same for edward.
Jake will always love bella as his true love, but bella loves him as family not as a loved one

Yes, if she was human. She would leave Edward, but I guess never will be happy. She will sacrifice herself as Jacob's imprinting is involuntary. She would be sad, but then she will know she'll die one day, and both of them have until... well forever. She's temporary to Edward really. But what happens when she dies is another question.
However, if she was a vampire, Jacob, a werewolf, a natural enemy of the vampire would not imprint on her in the first place.
Take love at first sight for us humans for example. Will we ever look at an animal, a shark perhaps, and fall in love with it? No, they're different species. Werewolves are, you can say, half human, so they can imprint on humans; it is half of who they are, who they were before they were werewolves. Vampires are not human, and imagine the smell, how would Jacob ever get used to the smell? The bitter coldness. Imprinting, I guess, is ... well, instinct?- It is part of who they are, involuntary, subconscious- And instinctly, a werewolf would not be friends with a vampire.
So... I think Bella WOULD leave Edward if Jacob imprinted, but only if she was human.

NOWAY!!!!!Bella loves Edward more than her own life.like she says she would go everywhere with Edward.if Edward died bella would die too."i can't live in a word without him."

no friggin' way!

Of course not! Jacob has already imprinted on Renesmee anyway. Edward is Bella's true love and they're married! Bella didn't want to be "that girl" and I don't think she would wan't a worse meaning of "that girl" if she divorces in her first year of marrige.

no she wouldn't.i know this because i've already read the last book.

ofcourse not what the hell anyway in eclipse when bella went 2 see jacob and i think quil imprinted on that toddler bella asked jacob so thats it she have no choice he didnt say she will directly fall in love with him when they imprinted instead he said how cant she not like him hes so caring and everything so ofcourse she wouldnt have left edward

I don't think so. You mean after or before Bella had a baby?

Personally, no. The Twilight Saga is all about how Bella chooses Edward instead of Jacob. Edward is her true love, she loves Jacob, just not as much as Edward. Theres a part of me that sees Edward angry if he imprinted Bella, but unfortunately, Jacob does not imprint Bella so Edward-Die-Hards will have to plan it themselves.

she would not give up Edward
