Did any of the other Muggles who were bit not survive this moon?
Remy, don't feel terrible, yeah? It is what it is, and it's horrible that he was bitten in the first place. But you both had the right to live as normally as you can, and he had no right to harass or or do you harm. You made the choice to own up to your mistake, and then you've been working as hard as you can to mitigate it. He made his choices, too, knowing that might be the outcome.
