w has been acting disrespectful to my parents now. We live in their house and she doesn't pay rent, I do.
My parents have always been there for her and have loved her like a daughter. My mom takes her daughter to and from school and babysits her free of charge until we get home from work.
I feel angry and I'm having to bite my lip. I'm not sure what to do but I have a problem with W openly disrespecting them.
I wouldn't bite my lip. I would ask that while she lives in your parents house while you pay rent that she shows respect. If it wasn't for her daughter I would tell her "if you don't then you can leave". How nice of your parents to be so helpful with her daughter. I hope they can speak up for themselves. If you parents want to say something, please let them.
