Why does she still follow me on instagram?

Curious i stopped talking to a girl that goes to my gym bit before that we use to we exchanged instagrams & along the ways of getting friendly with each other I notice she was full of games so I stopped talking to her. But I noticed she still followed me & stays on top of my stories. I’ve stopped following but I almost feel like she’s keeping tabs on me but for what? I expected what every other girl would do just unfollow and do the same back. What you you think?
