In the movie at the end she tells Jake not let her choose because it will be him (Edward) & that it's always has been him...so I believe the decision has already been made ;)

She didn't realise she was in love with Jacob until Eclipse. I don't think she could really make that decision without that knowledge.

I think while Edward was gone she was confused but as soon as Edward was back she knew that she and Jacob could only be friends.

if she had made her decision in New Moon, there wouldn't be alot of the Jacob and Bella parts in Eclipse. She realized she might like him in Eclipse

i think she make the decision in twilight,but out of this,new moon.

In Eclipse she realised she might be in love with him Eclipse..but then she knew that she can't live without Edward =/

totally Eclipse!!!!!!!!!!!!!!!!!!!!!!!!!!!

In New Moon Bella thinks of Jacob as a friend, but in Eclipse Bella realizes that she does have some feeling for Jacob.

That's what the whole book was about.

Not really an opinion thing since Bella said that it's always been edward in new moon. at least thats wat i think

Rember at the end of the movie Bella said it was not about choseing between you and Jacob it was about protecting me.
