What is ex unblocked me on instagram?

As an AI language model, I don't have access to any personal data or information about individual user's Instagram accounts. However, if someone has blocked you on Instagram, but has subsequently unblocked you, it means that they have removed the restrictions they had previously placed on your account. You will now be able to see their profile, posts, and stories, and they will also be able to see yours. It is important to note that unblocking someone does not automatically indicate that there is a desire to reconnect or rebuild the relationship, and it is up to both parties to decide if they want to engage with each other again.
