Do any of you guys know this movie?

Where this guy is constantly bullied at school, cause him and his
family are witches. And this girl tries to be friends with him cause
she doesn't really care if he's a witch or not. Later on in the movie
him and that girl are being chased by everyone in the whole village,
and those two are trying to break the curse the cousin did a long time
ago. And if they don't stop the curse in time, everyone shadow will
kill them I think. At the end of the movie the guy finally found out
how to stop the curse but the only way to stop it, he has to kill
himself. And when he's dead, the girl starts crying, only to find out
that the guy did not kill himself, that a guy shot him at the back of
his head far away, so the curse was still there.

I really want to know whats the title of this movie ;o
It's been like 3 years ago since I saw the movie.
