How could I be following someone on facebook who I did not hit "follow" for?

[Laura Keohokalole]

I was scrolling through my Facebook news feed and came across a "story/notification" from someone whom I had a falling out with and haven't been friends on Facebook with for a few months now.

Wondering why the story had come up, I clicked this persons name and it said on the "follow" icon on her page that I was "following" her. How could this be possible when, 1: We are not even Facebook friends anymore and, 2: Even when we were Facebook friends, I did not select the "follow" option. I don't "follow" anyone on Facebook so I find that strange that out of no where it shows up that I am following her.

Side note: Could it be a Facebook glitch? Because recently I have been getting another girls (I AM friends with her) status updates received as an actual notification when I go into Facebook. It reads
"(Insert name) updated her status to: "..........""
I then went to her profile and saw that I was not following her, nor had I starred her as a close friend, AND we have been Facebook friends for a while and just recently in the last few weeks this has started happening.

I'm wondering if it's possibly a Facebook mistake?
Someone just answered that "I never unsubscribed from them" but in my question, it clearly states that I did not ever hit "follow" on this person's profile even when we WERE friends on Facebook. Just wanted to make sure that it was clear. I have never "followed" anyone.

it's not a mistake, you just dont understand how facebook works

here's what happened

you were friends with someone a while back, and then had a falling out, so one of you de-friended the other

but you didnt also unsubscribe from them (they are two different things), so you are still "following" them, but you only get to see their public updates

again, you dont seem to understand how facebook works

when you become someone's friend, you automatically get subscribed to their updates - subscribing is the same thing as following

you dont have to click on a follow button when you become their friend to be following them

get it now?
