step daughter

Being pregnant making me hate my step daughter alot I don't even want to be close to her. The way she is with her dad and my mil is very manipulative always throwing tantrums and shouting when no one listens to her. Hubs and mil always give in. I had enough of it, she gaves me anxiety! While I was resting/sleeping she will keep on slamming the door and shouting non stop and I'm at my 8 months pregnant now! Talk to my husband about his daughter being this way he doesn't seem to be listening to me!!
