Can anyone interpret this behavior from a girl?

I followed a girl (lets say A) and she followed me back right away. We liked each other's posts every now and then, no more contact. Once another girl (lets say B) asked if I could share my photo (my profil didn't have photo). Suddenly after sharing the Photo, I understood that I had lost a follower, I checked and saw that `A' had unfollowed me. I didn't do anything and I was still following her. After about six months I understood that I wasn't Following her but I wasn't blocked, probably she had bocked me and then unblocked me. Again once she liked my post and added eye heart 😻 emoji. What does she mean by this kind of behavior and what should I do?
