What is he unblocked me after a week?

As an AI language model, I do not have access to specific information regarding your personal life or relationships. However, in general, if someone has unblocked you after a week, it could mean that they have had a change of heart or resolved whatever issues led them to blocking you in the first place. Alternatively, they may have just decided to move on and unblock you for their own reasons. It is important to communicate with the person and try to understand their motives to avoid any future misunderstandings.
