I (30F) has a mildly rocky family life. To cut short, my parents coddle my sister (40F) to the point that she is so toxic, it tires out everyone. The worst part is when she goes on her rampage, it effectively impact everyone. Examples of stunts she pulled: 1. Steal our family land given as inheritance to us 3 siblings and just took it as hers 2. Told people that my dad molested her and me which led to me being questioned by relatives 3. Stole upwards of 300k of various people's monies including mine 4. Was a drug user, exposing me to it when I was 13 y/o by asking me to take it with me (without me knowing of the contents) 5. Chose to stay with her husband after he tried to sexually assault me I can write entire telenovelas if I were to list them out one by one. Point is, she mess up, we had to clean it up.

I cried tonight because she did something again that led to some discoveries of mine. She blew up in the family WhatsApp group claiming people were victimizing her. Nobody is. People were just asking why is she getting the family land when its supposed to be shared with myself and my brother. Of course as the blow up was public, people were asking questions. I had an hour long conversation with my uncle who now understand that I have been framed for so many things. This also meant I just discovered how much lies she has been telling to people, causing my family to see me in a bad light. I know I'm not perfect but I try my best to be a decent human being. Have a normal family, a stable career, take care of my mother, put in effort to have a good relationship with the extended family.

I then spoke to my mother. Like I mentioned at the start of the post, she has coddled my sister since little. My question to her was "What is the punishment for her embarassing the family tonight, spreading lies about me, on top of other stuff she has done?" She answered "Nothing. Let's just observe ". I just replied, "Okay you never cared to care for my feelings nor wellbeing. Your other daughter can take care of you. I'm done. Good night" and blocked her. My pain is amplified when my parents didn't do anything when sister's husband tried to molest me 8 years back and I told them about it. They just maintained a relationship with him and of course her, and expecting me to just heal. This is because she is so disruptive that "Its better for her to have a husband than not". Some family members even told me to just move on from the trauma. Yeah right like thats so easy.

Thing is, my mother has severe anxiety. With my dad's passing, she has gotten frail, scared and easily sad. But I have time and time again told her, "I dont need your money or inheritance. I just want you to teach your daughter a lesson by giving her the dued repercussion. Or else she won't learn."

So AITA?

Edit: Many are talking about the possible molestation. I get your POV and understands the importance. But I am hoping to get a view on my relationship with my mother. Cos honestly, I don't think I need to put up with my sister's bullshit. I didn't give birth to her and I don't think I should take the hit for her craziness.
