Hung up on narcissist parent who called at 3am. SHOULD I feel bad?

My mother told me to move to NC in 2023 after I was going through marriage issues. I put my last 65 dollars in the tank to come to her. When I got there she didn’t pick up the phone until 12am and told me to come over, that’s when she told me she couldn’t let me live with her. I was prepared for that and had to sleep in my car off and on from 2023 till around 2025 I missed my grandmothers passing because I wasn’t speaking to my mother who was her caregiver. My mother was very evil to me growing up when she would get mad I remember her ripping my hair out my head with a bread still attached to a hair bow, and I remember she shook me until my nose bled. I recently went back to my husband around Christmas and my mom invited us to come over so she could give a gift to my son. For some dumb reason I wanted to feel the aame family feeling my husband felt with his and I brough my son and husband over there. When we got there my mom talked on and on about her self, acting like she cared about me when the whole time I was seperated I was couch surfing with strangers because she tricked me to move here. Then she bragged about her career in the feild I tried to go to school for but when I was pregnant with my oldest son she threw all my clothes into the yard and kicked me out. Then I had to listen to my son, and my husband talk about how nice she seems. My husband even encourages me to have a relationship with my abuser and he never really takes a side. When I told him what she has done. That made me feel sick. When we left she hugged my son and and my husband and didn’t hug me. This was Christmas

Fast forward to now I’m on a work trip with my husband in beautiful Utah. I’m a luxury suite homeschooling my son. My mother calls me crying at 3 am about my step dad who is 10 years younger than her being in the er on a ventilator. He has health issues becahse he was morbidly obese and it stressed out his heart. He was hospitalized before Christmas last year and I just seen him he looked like he lost a lot of weight after the first visit. The last time he was in the hospital I let my mother call me all hours of the day and night and she would complain about his family his mother behind their back while smiling in their face, she was talk crap about her husband. I quit responding and she would leave me voicemails. I just feel nothing for her she kicked me out when I was 17 after my dads child support check ended she used that last check to find her second wedding and she never taught me anything about life and she waited until I was Persueing a career, everytime I started community college or tried to learn how to drive or live better for myself she would kick me out. Now I don’t want to talk to her I’m doing better in life and I realised I don’t want a relationship and I don’t want to care about things that happen in her life she never cared about me.
