TW- underage p*rn mentioned, child abuse etc

This is a very long post-

So I got abused growing up. By both stepparents.

Mum got with this guy. Had a kid with him. I moved in when I was 13. Kid would have been 3-4 if I remember correctly. My stepfather started abusing me within 6mths of their care. Hitting me, put my head through walls, singing songs about how ugly I was. List continues. Mum would try step in but she'd be hurt. Over the 4yrs in their care. She stepped in 3 times altogether. Usually she'd just turn up tv volume or something and act like nothing was happening. I did start defending myself. I bit him so hard once after he sat on top of me and squished me so I just chomped down. And drew blood. I bolted and escaped the house.

Anyway- meanwhile my sister. Spoilt. Like I think the 4yrs I lived there I never saw either parent even smack her for doing something wrong. She never got disciplined. She was being spoilt rotten. Her dad bought her everything she ever wanted. She named it. She got it.

This sadly lead to a spoilt brat of a kid. She hit high school and got a phone by 10yrs old. This bugged me because I had a no phone rule until 16...mums excuse was all her friends had one...so did mine. I get parenting changes per kid. But more so mad over how often this happened.

They did this school excursion. When I lived there I was not allowed on it. When she was...she got to go...instead of her and my mum coming to my wedding. Yeah mum missed my wedding to send a kid to a school excursion.

Mum even paid for her braces and stuff... I needed them to. Never got them.

Pretty much she has lived the life of everything I wanted. She got it instead. So take this bit to note. As Ill bring it back up later

Anyway- she became very bratty. By yr 8 started wagging. And running away from home. Why? Because her friends did it. She is a huge sheep. They do something. She starts following. She was 13. She started posting inappropriate photos on social media. In lingere etc. At 13. Many have said because shes reaching out for help...no because her friends did it. She started shoplifting...because her friends did...and stealing lingere. I had a friend sending me the screenshots. It was so revealing. If she was over 18 fine. But 13 no. She decided to run away in Jan 2018. All because her friend ran away. Bolted and she followed. We tried to report her missing but she would call the police and tell them she was safe. And that's all they cared about. Will point out mum did try get her therepy but she never attended. Couldn't drag her there.

Over time I had it. I started calling agencies and stuff to seek help for the graohic and sexual content she was posting. Everyone said kids grow up faster nowadays and I have to accept it. But isnt this classed as child por*ography!? She finally returned home after 1 mth and told mum she has her own conditions. If she didnt live to her conditions she will run away again. Like one rules is she can go out whenever she wanted. And have boys over and can lock the door...still 13 btw Mums response was to obey them. What!? If I breathed in the wrong direction her dad would have beaten the crap out of me. But she can get away with this attitude. Like no i dont want him to hit her but like take her phone or something

I ended up logging into her instagram to discover it was heaps worse than we saw. There were 50yr olds sending her pics and stuff. I took screenshots and called agencies and cops for help. Because mum wasnt doing anything. If I didnt do the dishes she'd confiscate my phone. This chicks doing all this and gets to keep it?

No one helped. All said kids growing up faster and I have to accept it.

That was it. I deleted every single post. My sister called me 48 x. Eventually her dad called. Now take in note Ive been kind to him since mum is with him still. But he calls and decides to abuse me for deleting her social media... I told him someone had to delete the nudity etc. Plus backstory abit this guy had been caught watching underage po*n to btw. He didnt know i knew...so i called him out on it. Asking if he wants to keep his daughters nudes on the net because hes checking them out to?. Oooh he hung up.

Mums response... well she abused me. I told her someone had to do something and she wasnt. I dont care if I look like a horrid bitch for it. I did what i thought was right. But Its been nearly 4 yrs and Ive only gotten 2 messages from them since.

I also found out mum married the dude...she married a guy that abused her daughter. Has hit her. Has done drugs and told everyone it was mum (meth). He has cheated and got caughter with underage po*n etc. And she married him. I was fuming.

My sister hit 15 and her new insta popped up and had her butt naked having s*x in her profile picture. You saw everything.

Now to my actual point- i removed all them from my life in 2018. When all this shit happened. Mums messaged me twice. My only message to them was when i found her new insta. I lost my shit because pretty much since mum had her. The 3 kids she had in this state have had 0 priority. She hasnt even called my brother once since this started. And he had nothing to do with it. No birthday cards ir Christmas cards while she's getting thousands spent on her each bday and xmas. Like we exist here to!?

I found out I was pregnant and due May 29th. My sister birthday funny enough.

Now- I decided to text mum. All i said is "I dont want you in my life but thought I should let you know. Im pregnant. Due in may"

And her reply- 3 photos of my sisters ultrasound and all info about her pregnancy and found out my now 16yr old sister has been trying to have a baby for 4mths and is also pregnant and is due 1 exact month before mine. On 29th april...on my bday to.

This kid got everything I wanted in life. Parents that loved her and put her first. Dental work, excursions, just love in general. And now she also gets the light of my pregnancy. Mum gave no shit about my pregnancy info or anything. Just immediately changed the topic to her and is like for 5 minutes can i be the priority and the subject.

I told her to shove it where the sun dont shine and go take her and this kid to candyland and have an amazing life. She won't be meeting my baby and she won't be called grandma or anything. She's nothing to this. I then replied more that every text from her from now on will be instantly deleted and i won't see them so don't bother

Am I being to over the top? Like telling her she won't ever meet it etc? Is this ok? I really feel bad. I don't have a mean bone in me. But i just don't want her in my life. Am i being horrid to the baby. Like never knowing it's grandmother etc. I really dont know what to do.

She let a guy beat me.. then married him. Didnt attend my wedding. Didnt give me medical care. Etc heaps i left out to. As i said. She has 3 kids here in this state and ever since the 4th came out she hasn't batted an eye on us 3.i don't want that in my life.
