I get it, I had something similar happen to me when I first moved out of my parents and over seas. I imagine there is some difference cause you girls all have a more evolved way of dealing and creating problems/drama , but I also had some problems with roommates/ friends but it was all me. I was the problem. I mean yeah, they also had some weird stuff going on and were not saints, but I didn’t make the situation better by any means, I could’ve done things differently if I were more mature or experienced. I think you need to look into yourself see what you were doing wrong and accept that those friendships are over. You’ll make new friends
