Maybe Ginny is sad because she misses her family while at Hogwarts. Harry would sit with her by the lake and listen to her talk about her family memories. He would remind her that she can always write to them and that they love her very much. He might also share how he sometimes misses his parents and how he copes with that feeling. Harry could give her a small gift, like a charm he made that has a little picture of her family inside, to cheer her up.
Ginny could be crying because she had a fight with one of her friends. Harry would first let her vent about what happened. Then he would help her see the other person's point of view, but also support Ginny. He would say that true friends always work things out in the end. Harry might suggest they do something fun together, like going to Hogsmeade for some butterbeer, to take her mind off the fight and make her feel better.
In the fanfiction world, miscommunication often plays a big role. Perhaps Harry was involved in some secret mission or task that he couldn't tell Ginny about right away. But Ginny, not knowing the real situation, might misinterpret his secrecy as cheating. For instance, he might be sneaking around to protect Ginny from a potential threat, but she doesn't see it that way.
One possible reason could be miscommunication. Maybe Ginny did something without fully explaining her intentions to Harry, and in the heat of the moment, he yells. For example, if she made a decision about their relationship without consulting him first.
Well, it could be that the fanfiction is trying to show Ginny's jealousy or resentment in a new light. Perhaps she's jealous of Harry's fame or the attention he gets. Or maybe the writer is simply exploring a 'what if' scenario where Ginny and Harry's relationship took a different turn from the start. In the original story, they end up together, but fanfiction allows for alternative storylines, and this could be one of them where Ginny hates Harry for various reasons that might be related to their different personalities, goals or the pressure of the wizarding world around them.
One possible reason could be jealousy. Maybe Ginny sees Harry getting too friendly with another female character in the fanfiction world. Another reason might be differences in their future plans. For example, Harry may be too focused on his Auror duties and Ginny wants more family time.
One possible reason could be miscommunication. Maybe Harry made a decision without consulting Ginny, like joining a dangerous mission. In fanfiction, authors often play with the idea of misunderstandings to create drama. For example, Harry might have thought he was protecting Ginny, but she saw it as him not trusting her enough.
In this fanfiction, Harry could comfort Ginny through his words. He might tell her that what happened in the Chamber was not her fault. He could share his own experiences of facing difficult situations and how he overcame them, making Ginny feel that she too can get through this tough time. For example, he could say something like 'I've been through a lot of scary things too, Ginny, and we've always come out stronger in the end.'
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.
Often, Harry shares his own feelings and traumas from the war with Ginny. By opening up about his nightmares, his losses, and his fears, he makes Ginny feel that she's not alone in her pain. They might sit by the fireplace in the Gryffindor common room, talking late into the night, and in this sharing, find solace in each other.
One possible reason could be a misunderstanding. Maybe Ginny misinterprets something Harry does and feels she can't stay in the relationship. Another reason might be that she feels overshadowed by Harry's fame and the pressure of being part of the Potter family. It could also be that she has some personal goals or dreams that she realizes she can't pursue while being with Harry and taking care of the kids.
One possible reason could be a misunderstanding. Maybe Harry was wrongly accused of something, and Ginny's temper got the better of her. For example, if there were false rumors about Harry being unfaithful in the fanfiction world.
