In Edward's absence, Bella got emotionally imbalanced and psychologically disturbed, hearing what she called as 'velvety, beautiful voice' in her head. She could not believe that he had decided to leave, compelling Bella to be oblivious about him 'as if he did not exist', thinking that was the best to get her off perils. Edward wouldn't give in to her request of being changed into a vampire to keep them eternally inseparable. It shook Bella off her normal senses, getting cold without conscious effort at fortifying blocks of truth to a conclusion that he didn't like her after all.
The moment that Victoria was hunting Bella to avenge her mate's (James) demise down Forks and La Push raised some levels of hysteria though which was rather less significant to lifelessness at Edward's while of inexistence. So came Jacob Black's rescue with Sam Uley to lead the pack, of werewolves, slaying Laurent and keeping an eye and ready claw on the rest of his coven for Bella's safety, sealed in away even from the slightest threat. Jacob underwent intense struggle on the process of revealing his true identity before which, he and Bella had some nice things to share like the motorcycle adventure, where Jacob truly came in handy on her secret deprivation. Upon discovering that he was a werewolf and it was his pack that saved her life from Laurent's assault, Bella did not have second thoughts of wholeheartedly accepting him, as a friend worth of lifetime trust.
This, however, was not sufficient to release her from delusions of Edward talking to her mind whenever she got near danger. Bella often revisited the forest that once sheltered the Cullens and decided to jump off the cliff one time to dare sorts of hell close by, believing strongly that, that was the only way to keep hearing Edward's warning voice. Even as she drowned in the black currents, her feelings were safe from anxiety as if every fear were instantly washed off upon such vivacious hints that clamored 'Edward did exist'. Up to that point, she was spared.
It went too abrupt that Edward didn't take note of those details carefully, with a sweeping assumption that Bella committed suicide yet missing the puzzle piece that Charlie meant to be gone for Harry Clearwater's funeral, one very unexpected phone call. Hurriedly so, Edward consulted the 'Volturi' with the solid intention of ceasing to live without her. But the Volturi wanted to keep him (for his special talents) and would not grant his death wish, so he opted to just expose himself under broad daylight to burn away. When Bella learned about it through Alice, she didn't waste a second and flew off, at all cost. She stood by Edward at the nick of time, dragging him away from the sun's wide view until the next thing they realized was dealing with the inviolable Aro (of the Volturi) whose mad curiosity about Edward's unique decision as a vampire stared red at Bella with cunning inquisition on which his cohorts kept attentive watch. At the slip of fortune, he was mad convinced by what Alice had forethought to be Bella's later conversion on account immortality. Soon, they three were escorted out of the Volturi's chambers and gathered with the rest of the Cullens.
In their privacy, Bella and Edward paid each other debts of explanation they'd grown thirsty of when the spatial difference was at the remotest it could get, breaking to the faintest of touch.
Back to Bella's place where the infuriated Charlie, having had enough, had lain on a serious anticipation, Bella and Edward came across Jacob midway down the nearby forest, stopping at a distance assuredly buffered from his zone. The men's calculating, concentrated gazes didn't flicker as they shifted colors and brief utterances held the air stung with a founding edge of future crises between what used to be 'legends'. Bella understood that she was the major subject of it all when Jacob implied it at reminding Edward that when a vampire bites a human in the land they were bound to protect, the truce would be over. At this, he nodded to settle so that they could leave before tendencies blurted out of control.
Bella was mad at the same time filled with compassion to the point of regret for Jacob, having chosen Edward to be with. She had promised to get back to him one day with remarks in the hope of patching up their friendship which he would have thought betrayed.
Bella brought the Cullens to vote over her transformation. On the contrary, Edward wanted to keep her soul intact and not abolish her rights of humanity. Where this opposition led was what the third sequel (Eclipse) was looking forward to answer.
