Am I wrong, is that harsh

My mother and I had the best relationship at one point but her husband told her not to get attached to my daughter. Lately she n I have been at odds simply because her husband does certain things that is overboard and she puts him over her kids but he treats her bad. Anyway when we argue she throws in my face what she buys my daughter n say pay it back. Im to a point that once we move out, my family will never see us again. Im to a point that I dont even bring my daughter and I out our room unless its to get her formula my food and shower or work
