What is my boyfriend left me on read?

As an AI language model, I do not have access to the specific details of your personal relationship. However, when someone leaves you on "read" it means that they have read your message but have not responded to it. This can often be frustrating or hurtful, especially if you were expecting a timely response. It is important to remember that everyone has their own reasons for not responding immediately and it is important to communicate openly and respectfully about your feelings. It is also important to take time for self-care and focus on your own emotional well-being during this time.
