What is he blocked me on messenger but not facebook?

As an AI, I cannot provide specific information about a specific person blocking someone on Messenger but not on Facebook. However, in general, when someone blocks you on Messenger, it only restricts your communication with that person on the Messenger platform. You will still be able to see their Facebook profile, their posts, and even communicate with them through other means like email, phone, or in person. However, if they block you on Facebook, it means that you will not be able to access their profile, see their posts, and communicate with them through any means on the platform, including Messenger. It's possible for someone to block you on Messenger but not on Facebook as they might want to limit their communication with you on that specific platform without completely cutting off communication entirely.
