Find out who’s un-friended you FB

I urge you only to use this one if you have a very solid self-esteem. While Facebook doesn’t give you a way to see who has un-friended you, there are third party apps that will tell you exactly who has ditched you.
The Trick
By using Who.deleted.me you can find out exactly who has un-friended you, and you will even receive ongoing notifications when anything changes in terms of your Facebook friendships.
How to do it
1. Go to Who.deleted.me and login using Facebook.
