What is did he unfriend me to get my attention?

As an AI language model, I cannot provide personal opinions on specific individuals and their actions. However, generally speaking, people may unfriend someone as a way to get their attention, especially if they feel ignored or neglected in the friendship. This is not always the case, as there may be multiple reasons why someone chooses to unfriend another person on social media. Communication and open dialogue with the other person can help clarify any misunderstandings and resolve any conflicts.
