First of all I m sorry if this isn't the right bord to post this, but you have always giving me great advice.

My mother is pretty much the black sheep of the family, we are 3 brothers all of which are from different dads. My older brother was born when my mom was 15, she ran away with her then boyfriend and my grandma had to go get her. I was born from her first and only marriage , but my dad cheated on her with different women, so she divorced her right after I was born. My little brothers father is an alcoholic, he used to beat me and my mother and there were many times when we had to get the police to get him out of the house, yet she will always take him back ( this action right here fucked my head for life).

I was always with my mother, always. I m the one who went to the shelter with when we had no place to go because the drunk dude spent all the money on beer and she was pregnant so she couldn't work, so we didn't have shit. We went through a lot of shit and poverty because of my mother's decisions (but there were also good times) . I took care of my baby brother after mom found two jobs (the guy was in prison, but if he wasn't I m sure my mom wouldve taken him back...) . After all i have a pretty special relationship with my brother because I pretty much raised him.

Now let's go to the present, my little brother is 12,years old, we live in a different continent , our economic situation is way better. Yet my mother is still trying to sabotage everything and you can't tell her shit because she screams at you and accuse you of controlling her life. I dont know what to do, I could say fuck it and look away and let her burn herself , but I can't let my brother live the shitty life I lived with her, I m still studying and don't have a good enough job to take care of us. She wants to bring my little brothers father back to live with her and my brother , and when I confront her about the life we lived thanks to him she says " your brother needs a father" or "things weren't that bad with him". I honestly feel like I am crazy, "things weren't that bad?", we had to live in the middle of the night in the fucking cold and that guy wanted to beats us up in the street! I know hamsters going to hamster but this is my mother and my brothers future, I need to find a solution one last time so she doesn't fuck it up again, atleast until my brother gets older.

I need your guys help, I m feeling so frustrated right now. How can I manage this situation?
