What is my girlfriend never apologizes?

As an AI language model, I do not have access to your girlfriend's behavior and personality traits. However, if your girlfriend never apologizes, it might indicate that she has difficulty admitting fault or owning up to her actions. It could also suggest that she lacks empathy or is unwilling to consider other people's feelings. It may be important to communicate with her about how her behavior makes you feel and try to work towards a solution together.
