One reason could be that some fans want to explore different character dynamics. The original Bella - Edward relationship is so well - known and often idealized, so making Bella hate Edward creates a whole new set of tensions and story possibilities.
Another option is to ask in Twilight - related fan groups on social media platforms. For example, on Facebook or Reddit. There are often fans in those groups who are really into exploring alternative storylines and they might be able to point you directly to some good 'bella hates edward fanfic'. They could also give you some insights on why this type of fanfic might be interesting to read, like how it can show a different side of the characters' personalities or how it can create a whole new set of conflicts and plotlines.
One type of fanfic could be where Bella tries to win Edward over. She might start by changing herself in ways she thinks he'd like, but it only makes things worse. Maybe she tries to be more involved in his vampire world, like learning about their history and traditions, but Edward still resents her presence.
I'm not sure about really well - known ones specifically on this plot. However, in the general Twilight fanfic community, there might be some hidden gems. You could try searching on specialized fanfic websites using these exact keywords. Sometimes, the less common plotlines like this are more likely to be found on smaller, niche fanfic platforms.
One common theme could be betrayal. Maybe in these stories Edward does something that makes Bella lose trust in him and thus start to hate him. For example, he might lie about something important.
One possible reason could be that some fans want to explore a different dynamic. In the original story, Edward and Bella are in love, but in this fanfiction, perhaps the writer wants to show a more complex relationship where Edward hates Bella. Maybe it's to add more drama or to explore an alternative storyline that goes against the typical romance.
Well, one place to look could be Fanfiction.net. There are often various takes on relationships within the Twilight universe. However, I'm not sure specifically which ones would be about Bella hating Edward. You might have to search using relevant tags and keywords on the site.
One scenario could be that Edward accidentally endangers Bella's family in the fanfiction. Since Bella is very protective of her family, this could be a major turning point for her feelings towards him. For instance, if his vampire nature attracts some dangerous vampires to Forks and they target her family.
It completely flips the perception. Instead of the loving Edward, we see a hating one. It makes Bella seem less desirable perhaps. Fans who read this fanfiction might start to view Bella as someone who has done something wrong to make Edward hate her, changing her from the love - interest to a more complex, possibly unlikable character.
