I (17M) am planning on moving out of my abusive home. The only people who know about this is my younger sibling (11F), my cousin (32F), and my aunt on my moms side (41F) and they've all known for at least 6+ months. My parents do not know yet because it would just not be a smart idea. Recently my aunt has been getting on my case about trying to help me mom get a divorce. Thing is, my mom always says she wants a divorce but never gets it. I'm always available to help her if she comes to me with questions, but am not offering advice to her because of how draining it is to me. I've also hit a point where I am undeniably being at least a bit selfish and moving out for my own mental sanity. The fact that moving out would also mean that I can actually study something that I care about and not be forced to do what my parents want. I'm also moving out so that I can get a stable job after college and be able to take care of my younger sibling once they turn 18 as well. To be clear this is not an afterthought for me and is on the front of my mind. I've also made it clear to everyone who knows that I'm moving out that a big reason I'm doing this is for my younger sibling and that it is a prime motivator for me more than me just wanting to study what I want. However, my aunt keeps talking about how she was worried about my mom and my sibling being left alone and how we need to stick together "all three of us" (me, my mother, and my younger sibling). I on the other hand, for better or worse, am past that point. I tried explaining to her for about 15-20 minutes about why I was past that point and how I have been doing much more than I ever should as a minor and why I need space from my immediate family. I made it clear I care about my mom and sister, but can't keep going on like this because it was making me feel incredibly awful. My aunt proceeded to get mad at me and I lost my patience because of the constant victim blaming I've been facing with all my family except for my cousin, younger sibling, and my aunt, until this point. So, I lost my patience and swore at her and told her that I was not going to speak about this anymore because it was pointless and we weren't going to get anywhere with it. She wants to talk about some "We have to help your mother" and I'm just like okay, I have been helping her since I was a child and if she doesn’t want to accept the advice I have given her then I will not offer anything until she asks and thats it. That's where I am at, that's where I will be. My aunt keeps begging me to do something and called me ungrateful for the support she's given me so far, and saying that I'm only thinking about myself and being selfish and not thinking about my younger sibling and abandoning my family. She doesn't want me to move out but that has been something I've been clear is not a sudden decision and has been extremely thought through. I feel like all I've done is stood my ground to protect my peace...AITA?
