What is if a guy calls you dude over text?

As an AI language model, I do not have the contextual information about your relationship with the person or the tone of the conversation. But generally, if a guy calls you "dude" over text, it could indicate that he sees you as a casual acquaintance or a friend rather than a romantic interest. However, it could also be his usual way of addressing people irrespective of gender and may not necessarily reflect his feelings towards you. If you are unsure about his intentions, the best way to find out is to have an open and honest conversation about your relationship and your expectations.
