Why Would a Girl Unfollow and Remove Someone on Instagram?

Someone I was very close to last semester, got along with really well, spent a lot of time with, and had hours-long conversations with suddenly unfollowed me on Instagram without any argument or conflict. However, she didn’t unfollow anyone else—just me. Do you think this is an emotional reaction, or is it simply because she has lost all interest? What is the most likely reason for a girl to do something like this?
