Missing my ex bestfriend

I miss my ex bestfriend. She use to live with me and my parents, they took her in when she didn't have anywhere to go, I got pregnant and moved in with my bf. My mom ended up asking her to move out in a few weeks (my parents were divorcing and they were selling their house) I try to talk to her whenever I get a chance but she always blows me off or post something about leaving people in the past quote on her IG or post old pictures of her new bestfriend and say something along the lines of the only girl that will be in her life and friend forever. I hope she's not angry at me for what happened. I tried to help as much as I could but her and my husband didn't get along because they are family but both their family ended up fighting so she didn't want to move in with me because of that reason. Should I just block her on everything? Should I move on but keep her still in my life through social media??
