When a girl calls you "buddy," it usually indicates that she sees you as a friend or someone she feels comfortable with but not necessarily romantically interested in. It's a friendly and casual term often used to address a male friend or acquaintance. In this context, "buddy" is used in a non-romantic or non-intimate way, similar to terms like "pal," "mate," or "friend."
If you have feelings for the girl and she refers to you as "buddy," it might suggest that she currently sees you more as a platonic friend rather than a potential romantic partner. However, it's important not to read too much into one term or label, as the context and overall interactions between you both will provide a clearer picture of how she feels.
If you are uncertain about her feelings, the best approach is open and honest communication. If you feel comfortable, you can talk to her about your feelings and see how she responds. Just keep in mind that not all relationships develop into romantic ones, and it's essential to respect her feelings and boundaries regardless of the outcome.
