Should I cut off a long time friend for the way she is acting or try to be understanding?

Alright, I’ll start off with how me and this friend of mine (let’s call her Mimi) have been friends for almost 10 years. I started college late, and she and another friend of mine (let’s call her Luna) introduced me to their friend group. I have made great friends with all of them despite me having social anxiety and getting over how overwhelming meeting so many new people is. Well that was last semester and a new semester started. Mimi joined a college club and has started hanging out with them more than me and the friend group she was originally in. Luna joined the club later and eventually our trio group chat we’ve had since middle school turned into a group chat about their club and how much fun they’re having. I have communicated so many times about how I’ve been feeling left out and don’t appreciate them having conversations about hangouts that I was not involved in. I was feeling isolated because my longtime friends were not hanging out or talking to me as often so I turned over to other people in our friend group to talk and hangout with. I became close with this girl (let’s call her Hana) because our close male friend drives us to campus. Mimi has noticed how close we’ve become and has become passive aggressive every time she talks to us. She told Hana “I see you’ve been hip to hip with *** lately” while they were working and it caught her off guard. Mimi has stopped replying to my text messages, and that’s fine. But what really hurt my feelings was when I was having an emotional breakdown and got ignored the entire night. I just thought “Would you even care if something happened to me?” I’d like to add that Mimi is very extroverted and has a lot of friends. I’m introverted and keep a small circle. When I communicated to Mimi about how I felt left out, all she told me was “It’s not my fault I can make friends and you can’t.” Why is it a problem if I have trouble socializing AND if I become close to another person?
