He loved her, but he loved her obsessively and controllingly. If she had returned his feelings for whatever reason, I think that he would end up accidentally being emotionally abusive to her because he'd be so scared of losing her. PREACH IT
The House Cup part // Severus snape, albus Dumbledore, Harry Potter, hp<<< I always forget that Slytherin won seven years in a row before this, which does make it sound like Snape gave them a big advantage.
This is so sad. The boy who never asked for help, because he thought it was wrong. Harry Potter :'( <-- add in the fact that Harry was supposed to be the amazing "Boy-Who-Lived" and you have an even bigger problem
