My boyfriend’s best friend unfollowed me on insta?

Anonymous
I checked instagram yesterday and realized she unfollowed me for no reason? I never talked to her, but she’s pretty close to my boyfriend and really good friends. Why?
She followed me because my boyfriend told her about me, but she never liked any of my pics. I don't know why she unfollowed me since she’s pretty close to him.

by the way she’s taken, then why she did that?
