I can't stand my stepdaughter. She might be awful or I might just be a jealous b-word. Either way, I'm about ready to bail.
That sounds harsh. Is there something wrong with your stepdaughter?
No, not really. I just want her to get out of my hair.
Even if you don't get along with her, it's wrong to hate your partner's child. You should work to improve your relationship with her.
She's just a kid. I don't have to like her, she should get out of my house and learn to mind her own business.
If you are in a relationship with someone has kids they are apart of the package. You knew this before you got together. HE might be hostile because she thinks you are stealing her dad away or something.
