bella is needy in some ways.
she thinks that he will disapear into hin air
so i guess she just makes sure she see's enough of him "before" he does..
and she is addicted to him.
but then again, Edward is needy to. (he needs Bella)
so i say its an equal situation.
Everyone is next in twilight but it is subtle u know? B needs E, E needs B, the cullens ccouples need each other,Charlie needs B, the Cullen family needs each other, but it's why we lovveeee the story!
