How can Harry deal with being rejected by his mates in the fanfiction?

Harry could try to find out the root cause of the rejection. He might start investigating if there are any external influences on his mates. He could also reach out to other characters for support, like some of the Hogwarts professors. And he might try to prove himself to his mates, by showing them that he's still the same Harry they used to know deep down.

He could also give his mate some space for a while. Sometimes, distance can make the heart grow fonder. By giving space, his mate might have time to think about their relationship and realize what they are missing.

One possible reason could be jealousy. Maybe Harry has some special abilities or has received more attention than his mates, which makes them envious. Another reason might be a misunderstanding. Harry could have been misinterpreted by his mates due to some miscommunication or false rumors.

Well, it could be that Harry Potter makes a big mistake in fanfiction. For instance, he accidentally endangers his mates. This would lead to them feeling angry and rejecting him. Also, differences in beliefs or goals can play a part. If Harry starts to pursue a path that his mates don't agree with, like getting too involved with a certain type of magic that they consider dangerous, they might reject him.

He should focus on self - improvement. Maybe work on his flaws like his impulsiveness or become more reliable. Percy could also try to expand his social circle. By meeting new people, he might find someone who appreciates him for who he is. He could also throw himself into his hobbies or work. If he likes fishing, he can spend more time fishing to take his mind off the rejection and also gain a sense of accomplishment.

Just accept it and move on. There's no point in dwelling on it. There are plenty of other fish in the sea.

Perhaps Harry tries to find the root cause of the rejection. He might start investigating if there's some sort of dark magic or false rumor spreading about him that has made everyone turn against him. He could question his closest friends or even seek out the help of some of the more reclusive teachers at Hogwarts to figure it out.

Harry might initially feel sad and confused. He could start to withdraw into himself, spending more time alone. Maybe he'll question what he did wrong to be treated this way.

In some fanfictions, Draco might initially become withdrawn. He could isolate himself from others, brooding over the rejection. For example, he might stop participating in social events he used to enjoy.

Perhaps the father is under the influence of some external force. In fanfiction, it could be that he is being blackmailed or controlled by a dark wizard. As a result, he has to reject Harry against his true feelings. Also, it could be that the father has made some big mistakes in his life and he doesn't want Harry to be associated with him because he thinks it will bring harm to Harry.
