Another reason might be miscommunication. Harry has a lot on his plate, and sometimes he might not express himself clearly. He could say something that Ginny misinterprets as hurtful, when in fact he didn't mean it that way at all. For instance, he might make a comment about her Quidditch skills that she takes the wrong way.
Ginny might become withdrawn. She could stop talking to Harry for a while and avoid him in the hallways at Hogwarts. This is a common reaction when someone is deeply hurt, as she needs time to process her emotions and protect herself from further pain.
Well, Ginny herself is obviously a major influence. Her own actions, words, and the way she presents herself to Harry play a huge role. Another character could be Hermione. She might give Ginny some advice on how to approach Harry or how to get him to notice her more. This advice could lead to Ginny doing things that make Harry start to like her.
One possible reason could be that Harry is too focused on his fight against Voldemort and doesn't want to put Ginny in danger. He might think that being with her would make her a target for his enemies.
One way Harry could be comforted is if his friends, like Hermione and Ron, step in. They could remind Harry of his worth and how Draco's words or actions are a reflection of Draco's own insecurities. They might take Harry to do something he loves, like a visit to Hagrid's for tea and to see the magical creatures. This would distract Harry from the hurt and make him feel supported.
One possible reason could be miscommunication. Maybe Annabeth said something without realizing how it would come across to Percy. For example, if she was stressed about a quest and snapped at him when he was just trying to be helpful.
The idea of Ginny hurting Harry in fanfic can also be related to character development. Fanfic authors may explore Ginny's character flaws and how they impact Harry. For instance, Ginny could be jealous of Harry's friendships with others, especially Hermione. This jealousy might cause her to lash out at Harry, making him feel hurt. However, through these difficult times, they can learn more about each other and grow closer in the long run.
One possible reason could be that Harry has been spending too much time on his heroic duties and not enough time with Ginny. Another might be that he made a decision without consulting her, like taking on a particularly dangerous mission. It could also be something as simple as he forgot an important date or anniversary.
One possible reason could be a growing apart due to their different career paths. Harry, being deeply involved in the wizarding world's security and Ginny having her own Quidditch career. Another reason might be the stress of living in the public eye. Their relationship may not be able to withstand the constant scrutiny and pressure from the wizarding community.
Maybe in the fanfic, Harry discovers some differences between him and Ginny that he hadn't noticed before. For example, their future plans might not align. Ginny might want a more settled life at Hogwarts or in the wizarding community, while Harry feels an urge to explore the wider magical world and perhaps even try to improve relations with non - magical communities. These differences could lead to their break - up.
Maybe in the fanfic, Ginny discovers that Harry has some unresolved trauma from his past, like his experiences with Voldemort. His nightmares and mood swings start to affect their relationship. Harry, on the other hand, might feel that Ginny is too overbearing in trying to 'fix' him. This clash of their approaches to dealing with his past could be a reason for the divorce.
