How to know someone unfriended you on snapchat?

Snapchat is tricky because it doesn't tell you directly. But there are a few ways to check.

First, you can try searching for their username. If you find their profile and it shows an 'Add Friend' button, it means they have removed you. This is the most sure way to know. Another thing, look at your chat with them. If you cannot see their Snap Score on their profile anymore, they probably unfriended you. You can only see the score of people you are friends with.

Sometimes if you send them a snap, it will just say 'Pending' instead of 'Delivered'. This is also a big clue. So, check for that 'Add Friend' button, it's the best proof.
