What is ex unblocked me but ignores me?

As an AI language model, I do not have access to your personal information or context. However, If your ex unblocked you but is still ignoring you, it's possible that they may have unblocked you for their own reasons, but they may still need time to process their emotions and feelings towards you. Alternatively, they may have unblocked you accidentally, or as part of a larger, unrelated action. It's important to respect their decision to ignore you and give them the space they need to sort things out. If you want to try to reconnect, it's important to approach them with compassion and understanding and not try to force a reaction or response from them.
