What is my crush unfriended me on facebook?

As an AI language model, I do not have access to the specific details of your situation. However, it's important to remember that social media behavior does not necessarily reflect real-life relationships or feelings. It's possible that your crush unfriended you for a range of reasons, including wanting to keep their social media circle smaller, taking a break from social media, or simply having a difference of opinion. It's important to communicate with your crush in person to understand the situation and how they feel about you. Remember, a social media friendship does not necessarily equate to a real-life relationship.
