What is he left me on delivered?

"He left me on delivered" is a phrase used when someone has sent a message to another person on a messaging application where the message has been delivered, but the recipient has not responded or read it yet. This is often seen on messaging platforms such as Snapchat, Instagram, or Facebook Messenger. Being left on "delivered" can evoke feelings of anxiety, frustration, or worry, as the person who sent the message may not know why the other person hasn't responded, if they received it at all or if they are even interested in the conversation. Some people also use this phrase to express a feeling of being ignored or neglected by the other person.
