Step Daughter problems

Anyone have an annoying jealous step daughter . I try so hard to love her but she has so many messed up characteristics just like her mom. There's really nothing to even like. She's rude , annoying and has no respect for grown ups. My husband doesn't do much to change that he just spoils her. Any of you ladies deal with that jealous step daughter stuff ? Or step daughters that you just can't seem to love?
