But since her near admission to him almost a week ago, Hermione is simply lucky to have him hold her close like this. After giving her a sincere apology for his behaviour, he has been skittish and distant, avoiding contact with her as much as possible – sleeping back in his corner bed again, and no longer allowing her to tend to his wounds. She knows what is going on, now that that initial shock of his reaction has faded from her. He is trying to push her away in anticipation of their separation. It's not that he doesn't care, it's that he does. He's trying to cut the ties their shared horror has bound between them so that it hurts less when she is safe and he is not, and she hates it even as she knows there's nothing she can do to stop him.
