Sister Drama - AITAH LONG vent post

I realized I’ve been holding in a lot lately and I’m so exhausted and feel so alone. I just need to vent about this. So, I’m 32yo and I’m 28 weeks pregnant. I found out in January! When I told my sister(29yo) her response was: omg I’m so so sorry… and proceeded to ask me what I was going to do. I wasn’t trying and I was on birth control, but I also know I didn’t want an abortion. My partner and I are pretty well off combined and even though we don’t live together, it didn’t really matter. Yes we were scared, yes we were nervous but he adores me and worships the ground I walk on. He never even suggested an abortion when I had even talk about it just in case. A few weeks after that, my sister who lives in Houston, came to visit for her friends gender reveal. We saw each other several times, hung out and she stayed at my apartment (context, I have 5yo who I share 50/50 custody one week off one week on with my ex husband. On the weeks he has him I stay at my bfs house the entire week) My mom had came down from Massachusetts and stayed at my apartment as well for a few weeks, and my sister stayed there too. My sister chose to give me a speech via text after I sent her an ADHD TikTok video, about how I seemed on edge and angry, and that my apartment was dirty and messy, and that I should go to a psychiatrist and get medicated. 1) I had a ROUGH week with my son’s behavior at school, he was hitting and kicking. 2) my ex husband is a narcissistic psychologically abusive POS who spent that week picking fights over articles of clothing 3) for context on who I am, I make damn near 6 figures, I maintain myself and my son no child support no nothing. I own my car, I pay for my own stuff, I have a very demanding corporate job, and none of my family lives nearby. I don’t have a huge friend circle because I moved around a lot growing up, but I’m very self sufficient and settled for a 32yo. 4) my apartment is messy because I have a 5yo boy, I have white carpets and they’re still white if you catch my drift and you can walk around in white socks on my wooden floor. Mess doesn’t constitute dirty. This hurt my feelings and when I expressed that she legit cut me off and didn’t talk to me for 3 months. Come March, we talk again, instead of asking me about my pregnancy and how I’m doing etc, she goes on to talk about an affair she’s having with some dude from her job where she’s only worked a month after being unemployed for 8. Her bf moved her from NJ to Texas into his house and she was let go a month into moving there and he supported her for 8 months while she figured her job situation out. So I mentioned to her after she spent a week talking about her affair how I found it hurtful that she hasn’t even asked me how I’m doing etc. since then our communication has been spotty. Im in the process of buying a house now with my BF. My sister asked me if I will still have my apartment in the first week of June back in May, and I wasn’t sure due to me being in the middle of closing etc. Fast forward to last week, June 2nd, she asked if she could come to my house and stay there after she had said she’s coming to stay with my dad back in May. I told her, due to the things you said to me about my place last time, I don’t think it’s a good idea for you to stay at my place, you never apologized and you suggested I needed to be medicated while pregnant over some toys on my floor and being upset about having a shitty week while enduring morning sickness, virtigo etc. she got very upset and said ok, and didn’t talk to me. She waited 4 days to come back and “apologize” and her apology went as follows: “im sorry that you received my advice the way you did, clearly the things I said offended you but that wasn’t the intention and I’m sorry you received it that way” verbatim. There was more said but essentially she took no responsibility for insulting me, and saying all the things she said and cutting me off and then asking for a place to stay. Her visitation reason was her friends baby shower. She never replied to me, she left me on read, and came to NJ, visited my son, went to her friends baby shower, hung out with other friends and I didn’t get a text, or anything, she blocked me from viewing her stories on IG etc. came and left. She’s my only sibling and I’m so so sad and depressed about this situation I do not know if I’ll ever be able to truly forgive her. She has made comments about my first son being her only nephew, and etc and she hasn’t really cared about this pregnancy. I’m unsure why, because my ex husband was an ASSHOLE who abused me and she’s so cool with him, they text they chat they video call but she doesn’t like my current partner or this pregnancy and I don’t know why. He’s literally the exact opposite of my ex husband. He LOVES me worships me, treats me and my son with love and respect. He’s sweet and emotionally intelligent. Has his own condo, has a great job. I’ve never been happier and she’s …… not happy for me? I don’t know what to do? Was I wrong for not letting her stay at my place? Am I wrong, for feeling like I can’t forgive her? Sorry for the long post…
