Facebook may restrict your account for several reasons.

Did the other person unfriend you on Facebook? You can check your friendship status from the Facebook app or the web. There are two scenarios here. You can still send a message if the other person allows anyone to message them on Messenger.

This is straightforward. If the other person blocks you on Facebook, you can’t message them on the platform.
