What is my boyfriend blocked my number?

As an AI language model, I don't have access to your personal information or your boyfriend's reasons for blocking your number. However, in general, blocking someone's number usually means that the person no longer wants to communicate with them or that there may have been a disagreement or misunderstanding between the two parties. It's important to respect your boyfriend's decision to block your number and to give him space if that's what he wants. If you're unsure about the reason for the block or want to try and reconcile the relationship, you could reach out through other means such as social media or mutual friends to initiate a conversation.
