Is it weird to call my crush's sis?

I mean, for as long as I can remember-literally since I was two-I've been dealing with my sister's abuse. She's so controlling and just plain mean that she won't even listen to anyone else when they try to talk some sense into her; if you start talking to her on the phone, she'll just slam it down. Honestly, she's made my life a living hell from day one.

When I was unemployed for five years straight, she used that against me and took custody of my son because I couldn't provide, calling me an unfit parent even though that wasn't fair at all. She accuses me of stealing, but trust me, she's done the same to me before-and worse! We haven't had a relationship in forever; it's like we don't even know each other.

She's got no friends and fights with everyone over petty stuff. My whole family is against her because of how nasty she acts towards us all. When my husband passed away and I lost my job, she took everything from me-including where I lived-and left me to fend for myself, homeless and hungry. She humiliated me in front of our mom's in-laws when she died three years ago, like we weren't even related.

I helped her out so maany times: financially, emotionally, you name it. But after my mom passed, she did'nt offer a single bit of help when I was down and out. She has no regard for anyone else's feelings or needs. Now, living with my grandfather where I grew up, she still claims it's hers while trying to take every last cent from me.

During the pandemic, her eldest daughter was having her matric farewell party, but instead of helping out, she made me feed her three kids as she sat there eating takeout! It's so frustrating. My son cries whenever I leave him with her, and now that I want to take him away, she refuses. She huimliated me in front of everyone at my mom's funeral too; she was even drinking heavily.

To add insult to injury, when she got married super yuong, no one even told me until afterward! It's like I'm invisible to her. I've forgiven her but we can't sit at the same table anymore; I just want what's best for my son now that she's going through something similar to what she did to me. The divine has surely seen all my pain and tears.

Today, she's unemployed with no cars and pretty much in a situation where she used to put others like me. A friend of hers is even taking legal action against her now. I just want my child back and to have nothing more to do with this person who's only ever wanted to take from me without giving anything back.
