One reason could be that Edward left her so abruptly in the forest. It was a really cruel way to break up with her, without any real explanation at the time. She was left completely heartbroken and alone, and that kind of betrayal is hard to forgive.
In the context of the New Moon story, his departure also put her in great danger. She was left unprotected and vulnerable. She had to go through so much pain and suffering without him. All these things combined make it understandable why she doesn't forgive him in the fanfiction.
Perhaps in the fanfiction, Edward broke a significant promise to Bella. Promises are important in relationships, and if he failed to keep one, it could lead to her not forgiving him. For example, if he promised to always be there for her but then abandoned her in a time of need. Also, his over - protective nature in a wrong way could make Bella feel suffocated and less likely to forgive him.
The Volturi also keep an eye on this situation. With Bella not forgiving Edward, there is instability in the relationship between the Cullens and Bella. The Volturi are always looking for any excuse to interfere in the Cullens' affairs. This unforgiving state of Bella could potentially give them a reason to step in, which would endanger not only Bella and the Cullens but also other characters who are associated with them.
It can add a new perspective to the fandom. Fans who are tired of the typical Bella - Edward love story might find these fanfictions refreshing. It shows that relationships are complex and not always about happily - ever - after. It can also inspire discussions among fans about the characters' flaws and what could realistically happen in such a relationship.
In some fanfiction, Bella might not forgive the Cullens because of a perceived betrayal. For example, if they hid something crucial from her again. It could also be due to them putting her in danger without her consent. Another reason could be a broken promise related to her transformation or her relationship with Edward.
In the fanfiction, it could be that Sasuke's unyielding thirst for power and his disregard for the consequences of his actions on those around him are reasons Naruto doesn't forgive him. Sasuke was so focused on his own goals that he often trampled on the feelings and safety of others, and Naruto, who is all about protecting and connecting with people, may find it hard to forgive such self - centered behavior.
Well, it could be that Edward returns to Forks after a long time away. Maybe he realizes he can't live without Bella. He shows up at her house, and they have a very emotional reunion. Bella is initially shocked but then overjoyed.
Maybe Gryffindor did something that seriously violated Harry's principles. For example, he might have endangered Harry's friends or made a decision that put Harry in great danger without his consent.
Well, that could lead to all sorts of intense and unexpected plot twists. Maybe it would force the other characters to take drastic actions to rescue her.
One idea could be that they decide to take a break from the chaos in Forks and travel the world. During their travels, they meet other supernatural beings and learn about different cultures. This would not only deepen their bond but also expose Bella to more of the hidden world. It could also lead to some self - discovery for both of them, as they see how they fit into this larger supernatural universe outside of their small town.
Another direction could be that they focus on building a normal life within the vampire world. They might start a school for other vampires or hybrids, teaching them how to co - exist with humans. Edward could use his knowledge of music and literature, and Bella could share her experiences of being human - turned - vampire.
