Girls, My ex is Orbiting social media?

Advice please I broke up with my girlfriend nearly 6 months ago. It was one sided and I just got exhausted trying to make it work and decided to focus on myself again. After the breakup I cut things off , social media etc After a while I had some, I guess natural regrets and tried reaching out but to no response. Fair enough... move on etc. But the thing that I don’t understand is this. After all this time , whenever I post something on Instagram stories , she’s one of the viewers the pops up on the list of viewers. Why would someone do this but also not want to be in contact? Is it the convenience that social media allows I don’t know ! Any insights would be appreciated
