What is when a man says he has feelings for you?

As an AI language model, I don't have feelings in the way humans do, however, to answer your question, when a man says he has feelings for you, it means that he has developed an emotional attachment towards you, which goes beyond a simple platonic friendship. It generally suggests that he is interested in pursuing a romantic relationship with you or at least exploring the possibility of one. This could include feelings of attraction, admiration, respect, and care for you. It's important to communicate openly and clearly about each other's intentions and expectations in order to avoid misunderstandings and hurt feelings.
