My ex removed the friendship with me on facebook after I posted a story

A month ago my ex girlfriend dumped me. After that she removed instagram (probably to not see reminds of us/heal more easely or something like that) and still she is not using it but kept facebook. Until yesterday I was in her friends, but yesterday after I posted a story on facebook I noticed that she removed me from her friends. She didn't open my story but for sure she saw I posted it.

What does it mean? She doesn't want to see stuffs that reminds me to her at all or she want to demonstrate me that she just moved on so she simply forgot me and removed me from friends? I am suffering so much and I want to reach out so bad
