Can you find out who unfriended you on Facebook?
Conclusion. Facebook doesn't notify you when someone unfriends you. To see who unfriended you, go to your friends' list and check who's missing. Additionally, go to that person's Facebook profile and check if they're still active on Facebook.
How can you tell if you have been unfriended by someone on Facebook?
A person does not receive any type of notification if you unfriend them on Facebook; you will just be removed from that person's friend list. If that person looks at their list of friends, they may notice that you are not in it anymore.
How do you find out who blocked or unfriended you on Facebook?
To make sure you have been unfriended and not blocked on Facebook, use the search bar on the homepage to search for the person's profile. You may find some other profiles with similar or even the same names, but if you don't see your friend's profile in the search results, they have blocked you.
