What is he knows i like him but does nothing?

Unfortunately, as an AI language model, I do not have access to your personal information or circumstances. Therefore, I cannot provide any specific information about the situation. However, in general, it is best to communicate openly and directly with the person you like to understand their feelings and intentions towards you. It is possible that they are not interested or may be hesitant to pursue a relationship for various reasons. Ultimately, respecting their decision and focusing on your own happiness and growth is important.
