Fanfiction about Ron and Hermione losing Harry's friendship: What could be the possible reasons?

It could be due to a misunderstanding. Suppose Ron overhears a conversation between Harry and Hermione that he misinterprets completely. He might think they are plotting against him or don't really consider him a true friend. So in a fit of anger and hurt, he decides to betray them.

Well, perhaps in the fanfiction they leave because of a prophecy. A prophecy might state that their presence near Hermione would bring great danger to her or to the wizarding world as a whole. So, they sacrifice their friendship and leave. Also, it could be due to some dark magic influence. They are forced by a powerful dark magic spell to stay away from Hermione, not having control over their actions.

Another reason could be their different views on how to raise their children. Hermione would likely be very strict with studies and following rules, while Ron might want a more laid - back approach. Disagreements over parenting styles can put a great strain on a marriage and could be a factor in their divorce.

It could be that they lied to Harry about something really significant. In the wizarding world, trust is built on truth - telling. If they told a big lie, like about the true nature of a magical object that was putting Harry in danger, he would be very angry. And if their actions led to the death of someone Harry cared about. For instance, if they made a wrong move during a fight that caused an ally to die, Harry would find it very hard to forgive them.

One reason could be envy. Hermione is often very good at academics and magic, and Harry and Ron might be envious of her success. For instance, if Hermione always gets top grades in potions class while Harry and Ron struggle, they could lash out at her out of frustration.

One reason could be jealousy. Maybe Ron feels that Harry is getting too close to Hermione and he's afraid of losing her attention. In fanfiction, authors often play with the characters' emotions. Harry, on the other hand, might see Ron as being too possessive of Hermione.

It's possible that Harry hates it because he has a certain image of Ron and Hermione in his mind. Fanfiction can sometimes create versions of them that are completely different from what he knows. For example, some fanfiction might focus on a love triangle that he doesn't think exists in their real relationship. This divergence from his perception could lead to his dislike.

Power could be a reason. If there's a chance for Ron and Hermione to gain a great deal of power by turning against Harry, some fanfictions might explore this. For instance, a new dark power might offer them something they've always desired, like the ability to reform the wizarding world in their own image. They might think Harry would oppose this, so they betray him to get what they want.

One possible reason could be a misinterpretation of their relationships. Maybe the author wants to explore a different dynamic where Harry and Hermione bond over Ron's perceived flaws, like his occasional laziness or his insecurities that might come across as annoying to them in this fictional scenario.

One possible reason could be jealousy. Maybe Ron is jealous of Harry's fame and the attention he gets. Another reason might be a misunderstanding. For example, if Harry makes a decision without consulting Ron in a crucial situation, Ron could feel left out and get angry, leading to a fight.
