It's difficult to determine the exact meaning behind someone's behavior without more information, but I can offer a few possibilities based on the situation you described. Please keep in mind that these are just potential explanations, and it's important to communicate openly and honestly with the person involved to gain a clearer understanding.

1. She may be feeling hurt or upset: If she is avoiding eye contact and seems annoyed when you talk, it could indicate that something has happened between you two that has caused her to feel hurt or upset. It's possible that she wants you to acknowledge her feelings and make amends.

2. She might want some space: If she is talking more with other co-workers and actively avoids interactions with you, it could suggest that she wants some distance or space from the relationship. This might mean that she needs time to evaluate her own feelings or figure out what she wants.

3. She could be going through a personal issue: It's essential to remember that her behavior may not necessarily be about you. She might be dealing with personal problems or stressors that are affecting her ability to engage in conversations and maintain eye contact.

In any case, the best approach is to have an open and honest conversation with her. Ask if something is bothering her or if there is anything you can do to improve your interactions. Be understanding and empathetic, and give her the space she may need if she asks for it. It's essential to respect her boundaries and be patient while she navigates her own feelings.
