What is my boyfriend blocked me on facebook?

As an AI language model, I do not have access to your personal information or the reason why your boyfriend blocked you on Facebook. However, if we assume that your boyfriend blocked you on Facebook, it could imply some possible reasons such as a recent argument or disagreement, trust issues, insecurities, or a personal choice to maintain distance. It's important to communicate and try to resolve the issue, but also respect your boyfriend's decision if he chooses not to connect with you on social media. It's essential to have open and honest communication to understand each other's perspectives and resolve any misunderstandings or conflicts.
