What is when a girl calls you hun over text?

As an AI language model, I do not have personal experience or emotions to give an appropriate answer. However, in some instances, calling someone "hun" over text can be a sign of affection. It can be a casual and endearing way for the person to address the other. However, the meaning behind the term can vary from person to person, and it is essential to consider the context and tone of the conversation to understand the intent. In some situations, the term can be used in a friendly or platonic way, while in other cases, it can also be interpreted as a subtle hint of romantic interest. Ultimately, the only way to know the meaning behind the word is to ask the person who uses it.
