Can’t remember the name of this horror/thriller movie

I can’t remember this movie, I think it’s a horror or thriller.
It’s about a guy who in the beginning of the film is a hockey player, and after game he goes home with his girlfiriend but on the way home they are attacked by a monster and he dies. He wakes up next to his girlfriend but now he’s a drug addict and his girlfriend who doesn’t remember him is his neighbour. He dies again and the last thing I remember is that it turns out he is also one of these monster things who eat other people’s fears, but he was cast out by his kind because he fell in love with this human girl.
