Am I wrong for wanting to cut my sister off after she said she’s “glad her baby is dead”?

Okay to make a long story short me and my sister are 2 years apart. My sister is in her mid 20s and I’m in my early 20s with her being the oldest. Growing up, we were always fighting with each other and weren’t that close. But towards my senior year of high school we started being closer and she even helped me out financially for my prom which was a big help since our mom is a blue collar worker and only makes enough for ends to meet

My older sister is everything that I don’t wanna be. She’s hateful, unhinged, promiscuous, dirty (she used to have the worst hygiene when we were living together), not to mention she has a horrible reputation in the city we’re from. Everybody knows her as a heaux. She’s already had 2 abortions and is barely 25. Her doing Onlyfans during the pandemic didn’t help those rumors either. Honestly she’s just so pathetic.

The only thing she has to her name is her looks because if she wasn’t attractive most men would be running away from her. She’s so toxic, one time she was arguing with her boyfriend and called the police and told them he had a gun and got him arrested for a felony and STILL got back together with him just to dump him this summer.

I’m nothing like my sister, I’ve worked my way to the top, I don’t dress s l utty or trendy, I’m working towards my masters, went to one of the colleges in the state. I’ve never used my looks or my sexuality to get by like my sister has. Despite all this I still love her.

In Early March my sister found out she was pregnant, at first she seemed kind of despondent & didn’t want to talk about it. She got pregnant by her crappy ex that I mentioned who she called the police on. She ended up miscarrying at 8 weeks and me and my mom had to rush her to the hospital while she bled everywhere. When the miscarriage situation first happened and she was still reeling from the pain and grief of losing the baby she was crying everyday, depressed, and her hair fell out a little bit too from the hormones so she was screaming and crying for a week straight. I decided to give her some space so she could grieve the loss and really take everything in but what did my sister do? She didn’t even rest, she didn’t heal. She didn’t talk to anybody about what happened. I told her to get some therapy years ago but she really needed it now. She just went on with life and never spoke a word of it not even to her ex.

This weekend she had called me and we were talking about everything, I asked her how she was doing etc. and we basically caught up. When I asked her was she okay she said she was but then she laughed and made a remark that really disgusted me.

She said “Well I’m lowkey glad my baby died. I wasn’t in any position to raise it anyway and my ex is broke AF so. Rather a miscarriage then another abortion.”

I immediately snapped at her and told her that’s not something to say she was happy or glad about, and how she should’ve been using birth control so that way the miscarriage wouldn’t have even happened. She was with her ex for YEARS with no birth control, this miscarriage she had this year is probably the 4th one in the past few years. We instantly got into an argument and I just ended up hanging up on her. It just triggered me so bad because I know there are couples out here wishing to get pregnant and would consider the baby a blessing. Not only that but I have fibroids and are still struggling with them so I’m very nervous about fertility and conceiving in the future or anything reproductive. My sister knows that. She just still decides to have crude humor. Even our mom agreed that what she said was horrible and disgusting. I know it sounds harsh but sometimes I wish she just wasn’t even around anymore. She makes my life a living hell with all her drama and she’s stained my reputation in our hometown because now I’m known as the sister to the biggest heaux in the city. I’ve gone to therapy about my childhood and my feelings towards my sister, but honestly therapy and situations like these where we argue is pushing me closer and closer to never speaking to her again.
