Should I talk to my former best friend/current roommate about her behavior or ignore it and move on?

I am 25F and have lived with my roommate (we’ll call her Mia) for going on three years. Mia is still very religious (I left our church a year ago) and has never had a boyfriend or really ever dated any guy for more than a couple of dates. She is incredibly avoidant and tuns away at the first sign of someone liking her and she is also very passive aggressive. I say all of this because these are things she has acknowledged about her temperament, but she has made seemingly no effort to change. I have been one of her best friends for over 15 years now, but in the last year especially, she has begun treating me very disrespectfully. She unfollowed me on Instagram (I even pointed it out and she ignored it), she is openly rude (eye rolling, being silent, looking away during conversation) to my boyfriend and my other friends that she has just met. She never asks me to hang out and outwardly avoids me even in our shared apartment (if she hears me come home, she’ll shut her door) but then when she’s texting me or sending me things on social media, she’s normal and fine.

A year ago, I started dating my current boyfriend. I have been so happy in this relationship and I’ve also changed and grown a lot in the last year in tandem with this relationship. I’m much healthier now, I’n generally better at communicating and the biggest difference is that I’m very secure in myself and a lot more confident than I ever used to be. None of these changes have been negative, and I also want to make it clear that this isn’t a case of me spending all of my time with my bf. I have gone out to dinner with my roommate and invited her to things, and I only see my bf on weekends typically.

My roommate approached me about us not renewing our lease in a few months and I was somewhat relieved because I thought I’d have to bring it up and didn’t want to blindside her. So we’ve established we’re moving out (I’m going to live with my bf and she’s living alone). My question is, should I try one last time to talk to her about all of this and salvage the relationship or do I just bare with the discomfort of living with someone who acts like they hate me but won’t communicate for the next several months and then assume the friendship fizzles out when we go our separate ways?
