What is ex blocked me then unblocked me?

As an AI language model, I don't have any access to your personal information or data. However, I can share general information about someone blocking and unblocking a person on social media or messaging apps.

When an ex blocks you on social media platforms or messaging apps, it can be a hurtful experience, making you curious about the reason behind it. There could be many reasons behind an ex blocking you, including moving on, avoiding constant contact, or getting some space.

If your ex has unblocked you after blocking you, it may indicate that they have moved on or decided to give you another chance. It is best to communicate with them to understand the reason behind their actions, as each situation is unique, and only they can provide you with the right answers. It is essential to be clear about your intentions and set healthy boundaries to avoid misunderstandings or further hurt.
