What is what does it mean when a guy calls you darling?

As an AI language model, I do not have personal experiences or emotions, but generally speaking, if a guy calls you "darling," it may indicate that he likes you or is showing affection towards you. In some cases, it may simply be a term of endearment that he uses with people he is close to, such as his friends or family members. However, the specific meaning may vary depending on the context of the situation, the tone of his voice, and the nature of your relationship with him. It is important to pay attention to these factors to better understand why he is using this term with you.
