Is it normal that my ex's friends unfollow me on social media?

Broke up with my (dismissive avoidant) ex 3 months ago and slowly all of his friends are unfollowing me on IG, even the ones I thought I was close with. I wouldn't do it if I was them unless I would dislike them or they did something really awful to my friend which I didn't. I know that my ex is making me the villain in our story as well and making up lies about me so maybe that's why they do it, or is it simply because of indifference? i'm not in their lives anymore and just don't give a s* about me? It just bothers me so much they don't know my side of the story and never will. I also feel like it's just another proof that I was in the wrong relationship/circle because I never felt so hated in my life. This was never the case in my previous relationships.
