Is OTHER wrong in the post ? POST : Hello, I try to make this as short as possible.
Little bit of a background: when I was living with my brother, mother and his third husband, they mistrested me physically and mentally. My mom has bitten me, scrathed me, pulled my hair and pulled my hands with aggression. My step father has hit me in the head with varoius objects (bottles, household stuff etc). Also they are really manipulative and forced me to do all the house work since I was 12. My mom once kicked me and his husband out of the house when I was 13 or 14 because she accused us for fucking behind her back, which is absolutely not true. And this is just a little bit of things what has happened. I'm no longer in contact with my mother or her husband.

My brother (as far as I know) hasn't ever got physical punishemnt, but this is not for certain. He's always been the favourite child, however he just sits and plays in his room because he is scared of our mother and is very anxous. Also he has said that there's no food in the house, just beer and they have been drinking for years everyday, I've witnessed it. Now, they force him to do all the housework.

My brother's father (not my father) wishes that my brother would live with him and my brother too, but they are too scared to ask my mother that. I asked the CPS to help with the moving out. Also they haven't let me to see my brother at all and black mail me by not letting us see each other. My brother is 14 and cries because of this, but my mother wants just to punish me.

So, after I filed the report, my grandma, who's always been on my side, called me and accused me of breaking our family and said that if I just could spend time with my mother, none of us would be unhappy. My former stepfather/brother's father, who's very dear to me, also won't talk to me anymore and my brother has blocked me from all the social media (this might be my mother's doing, last time me and my brother chatted, he wanted to see me so bad). 
I don't know if deserve this or not. 

tl;dr AITA for filing a case for my brother's neglect even if it breaks the family apart?
