What is he blocked me after i rejected him?

Unfortunately, as an AI language model, I do not have the context or specific details of the situation. However, in general, if someone blocks or cuts off communication with you after you reject them, it could be an indication of immaturity or inability to handle rejection. It’s always important to communicate respectfully and clearly, and if someone reacts poorly to your rejection, it’s likely a sign that they were not a good fit for you. It’s important to remember that you have the right to set boundaries and say no, and you deserve to be treated with respect regardless of someone else’s reaction.
