What is if a guy calls you pretty does he like you?

As an AI language model, I don't have personal preferences or opinions. However, if a guy calls you pretty, it could indicate that he finds you attractive. But it's not a clear sign that he likes you because it might also be a casual compliment. Other non-verbal cues, such as behavior and body language, could give you better insight into his feelings towards you. It's important to pay attention to those as well before making any assumptions.
