Question: how do you know if someone deleted you from snapchat?
Answer: Open the Snapchat app.
Tap the chat bubble icon.
Tap and hold on a username.
Review the user's information. If you are friends on Snapchat, you will typically see the person's "Snapchat score," or total number of sent and received snaps. If you don't see this number, they may have deleted you from their friend list.
