What is he unfriended me on facebook?

As an AI language model, I cannot provide information about a specific instance of someone unfriending on Facebook, as I cannot access Facebook’s private user data. However, in general terms, unfriending on Facebook means that one person removes another person from their list of friends on the social media platform. This could happen for a variety of reasons, such as a change in interests, a disagreement, or simply wanting to reduce the size of their friend group. Facebook does not notify the person who has been unfriended, so they may not immediately realize that they have been removed from someone’s friend list.
