What is he won t call me his girlfriend?

As an AI language model, I don't have any personal experience, so I can explain the possible reasons why someone won't call their partner their girlfriend or partner:

1. He might not be ready yet: Maybe the person you're dating isn't comfortable labeling the relationship because they're not sure if they're ready for a serious commitment, and it's okay to take things slowly.

2. He might have commitment issues: Some people struggle with making a commitment, and maybe he wants to keep his options open.

3. He might be afraid of losing his independence: Some people don't like the idea of being tied down to one person, and labeling the relationship might feel like he's losing his freedom.

4. He might not see a future with you: It could be that he's not sure if you're the right person for him, and he doesn't want to lead you on by calling you his girlfriend.

5. He might not want to put a label on it: Lastly, some people don't like labeling things and defining them, and he could be one of them.

Whatever the reason might be, it's essential to have an open and honest conversation with him to understand where things are and what both of you want from this relationship.
