From time to time, you might see that the number of your good friends has actually gone down. When that happens, it is possible that someone unfriended you; nevertheless, Facebook never ever sends alerts about unfriending.
Find Who Unfriended You On Facebook
Unfriending
When another user unfriends you, you no longer appear on her good friend list. If she has actually chosen to hide her profile content from non-friends, you might be not able to see parts of her profile that you previously had access to.
Even if you can still see her profile Wall, you will not be allowed to publish anything to it when you are not her buddy on the site. The opposite is also real-- somebody who unfriends you might no longer post brand-new material to your Wall.
Alerts
Notifications are a method for Facebook to communicate with a user when there is new activity associated with her account. While you are alerted of practically every new action a friend takes concerning your account-- such as sending you a message or publishing on your Wall-- unfriending is one of the couple of exceptions.
You will not receive a notice, either on your Facebook Wall or through email, when somebody unfriends you.
Reciprocity
When one of your Facebook friends unfriends you, she disappears from your good friend list just as you disappear from hers. Because of this reciprocity, you can browse your good friend list for buddies that you believe might have unfriended you.
If someone no longer appears on your friend list but you see that her profile still exists, she has actually unfriended you.
Factors to consider
Even if somebody vanishes from your good friend list does not mean she has actually unfriended you. It is possible that the user has actually deactivated her account, or that it was disabled by Facebook for some reason.
If you were unfriended and want to reconnect with the user, you can still send her a personal message or request her friendship again using the proper buttons on her profile page.
