getting threatened

so there is this guy I have known since I started high school, I'm in year 11 now and we have always been close friends. Anyway he started dating this girl named Jaynie, it was a toxic relationship all around as he always came to for advice. She never let him talk to girls but she could talk to guys and post about them all the time and she always got mad for little things which she ended up blocking out my friends feelings completely. I felt bad for him tbh but never tried to hurt there relationship. They broke up about a month ago and she has just been going crazy all over social media and posting things about him. When they were together our friendship drifted alot as she always got mad when I was around. But I never really saw why cause I myself have a bf and have for 7 months now. Then randomly I got a text from her that hardly made any sense for me.

Oh and btw she moved 2 hours away a little while ago. Generally I'm nice to everyone and if I ever was told I was flirting I would apologise but I never have been cause I respect there relationship and my own. I tried explaining but I got no where. I'm more confused why she is texting me and many of her friends have tried texting me but I'm not replying, I hate being involved in this petty drama but she has put people in danger a few times. And I did end up blocking her as she wouldn't listen to me and I was fed up with it x
