I just want someone else acknowledge this situation

I have been no contact with my mom since the end of 2023. She is an alcoholic, had a rough childhood until I was about 5 because of it, so I myself don’t hold a lot of memories from that time my sister whose 2 years older remembers everything and is very traumatized from it. My mom got sober when I was 5 because that’s when my little sister was born, and yes there’s been relapses through out the years but nothing longer than a week and she was always receptive to going to rehab. A few years after my parents got divorced my sister was a senior in high school, and I a year behind. she lost it and relapsed for about 2 years. My older sister had been moved out and I ended up leaving at the time. She seemed to be working on herself again, was sober. I let me her know I was pregnant with my oldest son, she was involved with everything. I always let her take him no questions asked. Keep him over night, going to fest and concerts and kid activities. All seemed ok that’s from 2017-2023. Then in 2023 not even a week before my son’s birthday that she was set to host I found out through family she was drinking again and had been for months. Which she had my son several times during those months even for overnight visits. My sisters and I held an intervention for her but I ended up going no contact. I was pregnant and high risk and going through a lot on my own end of life. She still contacted me everyday asking about the pregnancy on the off chance I would respond it was something like “I don’t want you involved in this part of my life until you are sober and honest” which would cause her to blow up at me she would get blocked until she found a new way to contact me. After I had my daughter she did call and ask if she could come meet the baby. According to family she had completed 2 separate rehab programs both of which she begrudgingly went to but she did go and as far as they knew she was sober. So I let her come to my house and hold my 1 month old baby. That was on a Tuesday she texted in a group chat that Friday that she’d actually been drinking for weeks and just wanted to see the baby before she went back to rehab. I should also add all of these relapses typically go hand in hand with her getting broken up with or getting a new bf. This woman is a few years shy of 60. So I pretty much told her to never speak to me or my kids again. Now my older sister is pregnant. So family functions are coming back into the picture. Her baby shower was this weekend. She asked how I felt about mom going and I said I would be civil as to not ruin her day. So she took our mom out to lunch and asked her how she felt about the shower. My mom said that she didn’t think she could go and not talk to me. My sister literally said the conditions to you coming are “don’t talk to Gianna” “don’t talk to her oldest son.” And “ don’t ask to hold the baby” and if she didn’t feel she could do those then don’t come. There was over 50 ppl at this party it was held in a small but 2 room event hall. I had gotten there early to get a table in the back, I had the stroller diaper bag, a large gift I had to like build there, my other kid. I just wanted to be out of the way. I had left my kids at the table to talk to my dad in the other room. When I got back to my table I saw my mom had arrived and walk talking to my son. I hesitated until she left and then went back to my table. My mom came back over with my grandma, I began a conversation with my grandma in which my mom interrupted 3 times going “hi Gianna” until I finally turned around and said hi. These tables only had 4 chairs btw so I had 1, my son had 1 and then an aunt came over to say hi and her table was taken over so she asked if she could stay so she got the 3rd chair. My little sister arrived and my mom went to help her carry stuff in. My little sister came and said hi and in seeing our table was full went and got a table with just her and the friend she brought. My mom then put her purse on the last chair and sat down at my table. I continued to talk to my aunt and grandma and my cousin who popped over occasionally. My mom repeatedly kept trying to start a conversation with me going to her car to get gifts she bought for my kids, stuff like my daughter’s “first” Easter dress which she won’t be wearing. F that. Then food was served buffet style and my mom went up and got a plate for herself, never once offered me help with the kids. My aunt watched them while I got mine and my sons. My aunt brought desert back to the table so I didn’t have to hold my daughter in line. My aunt took my son up to do some of the events like “guess the due date” all while my mom sat at the table and tried to talk to me. It was a short party about 4 hours and my mom sat at my table the entire time. Even though there was empty seats at my little sisters table, a table of my cousins, and my sister whose pregnant her partner’s parents where sitting at a table with open seats, also just any empty table. And then towards the end she was like “so am I not going to be able to hold the baby?” And I really wanted to be like “no b*tch” but what ever being the bigger person here I said yes, not like she’s ever going to see her again. And she walked off with my kid. So my pregnant sister did yell at her like “we told you we don’t trust you with the kids and yet you walk off with the baby after Gianna said yes trying to be nice like wtf is wrong with you.” So she grabbed my kid back. To which my mom went and cried outside. And then came back in and sat with my little sister. Though everyone left maybe 30 minutes after this. So my pregnant sister texted my mom today and said “I asked you for 3 things and you didn’t listen to any of them so you will not be invited to anything going further.” To which my mom replied “if Gianna was really that uncomfortable she could have moved” like are you kidding me. I’m so mad. But this woman makes me feel crazy sometimes. Comment tell me what yall think of my mom. Cuz I’m just mad now and it’s and it’s 2 hours past my bedtime and I have work in the morning.
