Does she hate me?

My dads new fiancé does not like my sisters and I don’t think. We have tried to talk to her in a voice that is hearable but she pretends she does not hear us and continues playing on her phone. When I ask her questions like where things are in the house because I am almost never there she answers in a really stern passive aggressive voice. Anytime my sisters and I do something wrong in her eyes she yells at my dad saying “Jeremiah we have an issue! The girls are picking on me (or) they lost something and it’s not my issue!” And my dad sides with her and he’s already not the nicest so he yells at us and she goes and talks crap about us to him in their loud enough o hear. I just want to know because she’s going to be my “stepmom” does she hate me? And if she does what do I do for her to like me???
