She might be devastated. Bella was deeply in love with Edward, so his leaving would be a huge blow. She could cry for days and feel like her world has ended.

The characters' development and their interactions are likely to be different. In the original Twilight, Bella's growth is mainly influenced by her relationships with Edward and Jacob. In the fanfiction, the angel could play a major role in her development. Maybe the angel teaches her about self - worth and a different kind of love that is more unconditional. Also, the interactions between the angel and other characters like the Cullens or the Quileutes could be completely new. For example, the angel might have a special connection with Carlisle Cullen due to his more moral and ethical approach among the vampires, which is not something we see in the original series.
