I’m being asked to break no Contact and need advice.

Title is self explanatory. I’ll give a bit of context. I have been NC with my NMom for about a year and six months. The longest I have ever gon without talking to her. Last time lasted like ( 3 months ). After like about a year she has been constantly contacting my father (who’s she been divorced for 25+ years) and brother asking about me. Asking if I’m ok? or how have a been and stuff and telling them to tell me to call her. I’ve told both my Dad and brother that I want nothing to do with her and do not want to speak to her. They’ve respected that, However from what I heard from my Dad she has kept contacting them on a daily and constantly asking about me. My Dad lets me know even though he mostly ignores her.

Last weekend I went to visit some family in jersey and to see my aunt. She is aware that I’m not talking to my mom and let the rest of the family know. They aren’t pushy or anything with the situation since they know my mom is “complicated”. Overall it was a very fun time however on our way back home my NMom calls my Aunt and it seems like they were having a regular conversation. While we were about to cross the street a car made wierd turn and seemed like it was going hit me. My Aunt then yelled “(my name) watch out!” While she was on the phone with my NMom. the guilt ate my Aunt alive and she ended up telling her I was there visiting. From what I heard my mom didn’t make anything of it and seemed normal. After the call ended we laughed about it. Tho she kept trying to call a while later.

Now fast forward to today while I’m at work I got text from my brother and call from my Aunt. The text from brother Said “ hey can I talk to you after work” I replied “yeah sure”. I had that strange feeling that it’s about my mom and when I went to
Answer my Aunt and it’s basically what I expected🤦🏽‍♂️. She now been calling my aunt non stop to ask her to tell me to call her, she even sent video to her of her crying 🙄 saying that she been sick and would like to speak to me. she even felt embarrassed and guilty giving me the me the message. I was on the clock so I couldn’t process right away what I should do and told my aunt to let her know that she spoke to me. But my Aunt does want me to talk to her just to calm her down. But in all honesty I could care less how my NMom feels.

This woman had made my life a living hell until I moved out. without going into too much detail she has Humiliated me, financially exploited me, has even physically assaulted me both when I was a kid and even as an adult. Lied about me to other people. Ruined a lot of my relationships when I was a teen and has even tried putting me and my brother against each other like the list can go on. I have no love for this woman and have been living my best life ever since I cut contact with her and even started therapy. However she seems to keep harassing other people to contact me and while I’ve never intended to break NC though I do feel a bit bad for my aunt. How do ya’ll think I should go about this? any advice is welcome. I’m thinking of just telling my aunt to let her know that I do not intend to contact her but I honestly I only really feel bad for my Aunt since she’s just so nice to me and I know it will make her feel really uncomfortable to pass on my message.
