Determining if someone has unadded you on Snapchat can be a bit challenging, as the app doesn't provide a direct notification for such actions. However, here are a few indicators on How to Tell if Someone Unadded You on Snapchat friends list:

Check your friends list: Open the Snapchat app and go to the Friends screen by swiping right from the camera screen. If you notice that the person's username is no longer listed or has disappeared from your friends list, it could indicate that they have unadded you.

Look for their name in your chat history: Scroll through your chat conversations within the Snapchat app and see if you can find any previous messages or snaps from the person you suspect might have removed you. If their name or messages are no longer visible, it might indicate that they have unadded you.

Pay attention to your Snap score: Your Snap score is the sum of all snaps you've sent and received on Snapchat. If you were previously exchanging snaps with someone regularly, but your Snap score doesn't increase or changes significantly, it could suggest that they are no longer connected with you.

Try sending a snap or message: Send a snap or message to the person you suspect might have unadded you. If the snap or message doesn't get delivered, or if you see a gray arrow instead of a filled-in arrow, it suggests that the person has removed you from their friends list.

Mutual friends' friends list: If you have mutual friends with the person in question, you can ask them to check their friends list for the person's username. If they can still see the person on their list, but you can't, it might indicate that you have been unadded.
