[[ I hate what Tonks made Remus become. Their relationship was based on her selfishness and it ruined Remus as a person.]]
Where is your evidence of this? I think she made him a better person. She wasn’t selfish at all. There is more about their relationships in the books 6 and 7. That we don’t get in the movies. But I’ll give you a rundown here. Remus knew of Tonks’ feelings for him, when and probably before her patronus changed. He rejected her advances because he thought that he wasn’t a whole person because of his lycanthrophy. And he thought the age difference between them was a bigger deal than it actually was. In the end what made him accept her into his heart, was when he saw that Fleur wasn’t going to stop loving Bill because he had been attacked by Greybeck. He may not have understood why Tonks wanted him but he understood that she loved him, and in that moment that was good enough. In book 7, he shows up and Grimwald place and asks the trio if he can join them, because he thinks he has made a grave mistake in marrying Tonks, and he is convinced that their unborn child will be a werewolf (impossilble by the way). He is upset and Harry gives him a verbal beating and brings back down to earth. (I agree with what Harry says James wouldn’t have wanted Remus to leave his wife and unborn child.) So he goes back to her. Even in the movie there is a deleted scene where Tonks finds Remus, and hugs him. He tells her she shouldnt have come. and she says that Teddy is at her mother’s, and that he will sleep till dawn and snore like his father and that it’s Remus that needs her tonight. And then in the scene where Harry uses the resurection stone, Remus says that Teddy will understand that his parents died trying to make the world a better place for him. Now, all that being said can you really truly say that Remus was ruined as a person. It seems to me as though Tonks pushed him to be a better person. Have you heard of the saying; “Behind every great man is an equally as great woman.” That is true for Remus and Tonks. Now I’m done with my rant.
This ^. Anyone who says Tonks was selfish at anything really hasn’t read the books (or watched the movies. There’s way too little Remus&Tonks in it to notice their character at all)
