One possible reason could be the stress of Harry's fame. His status as 'The Boy Who Lived' might put a lot of pressure on their relationship. Constant media attention and public expectations could lead to arguments and a growing distance between them.
Maybe in fanfiction, Ginny discovers that Harry still has some unresolved feelings for Hermione. This could create a rift between them and lead to a divorce. It's not uncommon in fan - created stories to explore complex love triangles that were not fully resolved in the original series.
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.
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.
One possible reason could be miscommunication. Maybe they had a big fight over how to raise their child and Ginny, feeling unheard, decided to leave. Another reason might be external pressure. For example, if some dark forces were targeting their family again and Ginny thought leaving would keep Harry and the child safer. Or perhaps Ginny had some personal issues she couldn't deal with while being in the family, like feeling she lost her own identity in the relationship.
Well, it could be due to the stress of their relationship. Harry had a lot on his plate, being the hero and all. Ginny was also a strong - willed witch with her own ideas. They might have had an argument about their future together. For example, Harry might be worried about Ginny's safety if they stayed together, given his dangerous life. Ginny, on the other hand, could be frustrated that Harry was trying to push her away for her own good. Another possibility is that they could be crying over the state of the wizarding world. After all the destruction caused by the war, seeing their beloved Hogwarts in ruins or the wizarding community divided could be heart - breaking for them.
One possible reason could be that Harry is still haunted by his past traumas and feels he's not in the right mental state to marry anyone. His experiences with Voldemort and the losses he's endured might make him reluctant to bring Ginny into a potentially unstable future.
Maybe Harry has some unresolved issues from his past, like the trauma of losing his parents and many of his friends during the fight against Voldemort. These could make him hesitant to enter into a marriage with Ginny. He might also be worried about how the wizarding world would view their marriage, especially if there are still some who oppose him or his family.
One possible reason could be that Ginny has seen Harry change a great deal during the war. Maybe the war has left Harry with a lot of emotional baggage that he's not dealing with well, and Ginny doesn't know how to handle it. So, she decides to give him some space by ignoring him for a while.
One possible reason could be that he might fear for Ginny's safety. In the wizarding world, there are always threats from dark forces. Harry has already lost many people he loves, and he might not want Ginny to be in more danger because of their relationship. Another reason could be that he wants to focus on his own personal growth and exploration. Harry has spent so much of his life fighting Voldemort and dealing with the wizarding world's problems that he may feel he needs time alone to figure out who he really is without the added pressure of a marriage.
