What is he left me on read on snapchat?

When someone leaves you on read on Snapchat, it means that they have read your message but haven't replied to it yet. This can be frustrating for the sender as they may be waiting for a response, but it doesn't necessarily mean that the receiver is ignoring them. There could be a variety of reasons why someone hasn't replied, such as being too busy, not knowing how to respond, or simply forgetting to reply. It's important to remember that everyone has different communication styles, and not everyone will respond immediately. If you're feeling anxious about being left on read, it may be helpful to communicate your feelings to the other person and ask for clarification on what their silence means.
