actually i do think Wuthering Heights is a love story.
like in one way or another it all comes back to love and hatred, which more often than not in literature are simply two faces of the same medal.
sure it's twisted, sick, and unhealthy, but it's still love and just because it doesn't give you warm fuzzy feelings doesn't mean it should be dismissed.
i think y'all just need to change your definition of the words "love story".
