Just need to vent a bit.. My father knows that I'm moving in

Just need to vent a bit.. My father knows that I'm moving in July, yet he still thinks I'm going to stay and watch my siblings. I'm not the only one that's eligible to watch them, my brother (that is a bit younger then me) is here, too. My brother is also a bit mad about me moving only because he won't be able to get a job since I won't be here to watch the younglings. What irritates me the most is that when I ask my dad for advice on moving, he asks me why am I asking. Saying, "What do you think you're doing? You're not leaving at all." I get that I'm his first daughter, but I'm old enough to make my own decisions. He continues to put me down and telling me that my mother's passing is my fault. Excuse me .? I get that he's mad, but to stoop so low as to saying that it's my fault is ridiculous. I am moving, regardless. I don't want to stay in this toxic and depressing environment.

You have to take care of yourself, and ensure your needs are met! Do you have a set moving plan?
