Both of my (19m) parents were addicts. I was their oldest kid and I have two younger siblings (13 and 11) from my parents relationship. My mom died a year after my youngest sibling was born from complications of trying to get off drugs without the right help. I had to step up and take care of us because my father was still off his head. Eventually CPS stepped in and removed us from my father.

I was separated from my siblings because they were easier to place than I was. I was used to caring for them and we clung to each other. I wanted to take care of them and they only wanted me. I still used to see them. But eventually that stopped. My siblings knew it would happen too. They told me they heard their foster parents talk about how they'd adopt them and then end the visits we had. I tried to tell my case worker what happened but she didn't believe me. But once the adoption was final I was no longer allowed to see them.

A few months later my father started showing up. He said he'd been sober for almost two years. That he'd signed away his rights to my siblings back then and he knew they'd been adopted out. I was so mad. I asked how he could do that knowing I wasn't being adopted with them and he said he worked hard to make himself fit to get me back. He said he had a partner and she was going to be there for us. I told him I didn't want to live with him again but he said it would be better. We'd be a family.

By the time he had proven himself enough and I was returned to him, his partner was pregnant. I was 15 at the time. I was 16 when their kid was born. The household was toxic. I hated my father for everything. I hated him for having another kid after letting my siblings go. He and his partner tried to make me that kind of brother to their kid but I told them I didn't want their kid, I wanted my siblings and I wasn't going to see their kid as one.

She told me she didn't want her kid to grow up unwanted and to feel the burden of my father's failures. I told her that wasn't my problem and she chose to have a kid with a man like my father. She tried really hard to make me interact with her kid but I avoided them (her and the kid) as much as I could and I left their house a few days before my 18th birthday and I stayed in a shelter for a while before getting a job. Now I'm in a small place with some others.

They kept tabs on me and have reached out repeatedly asking me to have the relationship with their child and offering all these ways I can do it without my father but I said no every time. Then I got a new number but my father's partner tracked me down anyway and told me I need to do this because her kid deserves better and is my flesh and blood too. I rejected the offer again. Then one of my roommates started on my case about being an ass to a little kid and how at least I have family unlike them. So now I have a roommate with an attitude over it.

AITA?
