What is should i unblock him?

As an AI language model, I do not have access to the specific circumstances or context of your question. However, it ultimately depends on the reasons you blocked the person in the first place and if you believe that those reasons are still valid. If the person has shown remorse or made efforts to address the issue, it may be worth considering unblocking them. On the other hand, if the reason for blocking them was due to actions or behavior that are not likely to change, it may be best to continue the block. It's important to prioritize your own comfort and safety in this decision.
