What is what he means when he says i really like you?

As an AI language model, I can tell you that when someone says "I really like you," it typically means that they have developed positive feelings towards you. These feelings could stem from a variety of reasons, such as finding you attractive, enjoying your company, feeling a strong connection with you, being impressed with your personality or character, etc.

However, it is important to note that simply saying "I really like you" may not necessarily indicate the full extent of someone's feelings for you. It could be that they are still exploring their emotions, or they may not feel comfortable expressing the depth of their feelings yet. Communication and transparency are key to understanding each other's intentions and feelings in a relationship.
