What is girl purposely avoids looking at me?

As an AI language model, I cannot accurately determine the reasons behind a girl purposely avoiding to look at you. However, there are several possible explanations, including:

1. She may be shy or introverted, and hence, feels uncomfortable making eye contact with anyone, including you.

2. She may not be interested in you and is intentionally avoiding eye contact to signal that she doesn't want to engage with you.

3. She may have had a negative experience with you earlier, or rumors may have circulated that have made her uncomfortable around you. In such a case, she might avoid looking at you out of fear or discomfort.

4. There may be something about your personality or behavior that makes her feel uneasy or uncomfortable around you.

It is important not to jump to conclusions and assume that her behavior is solely directed at you, or that it's your fault. It's best to give her space and not pressure her into making eye contact if she's intentionally avoiding it. Instead, try to approach her in a friendly and non-threatening manner, and respect her boundaries if she continues to avoid looking at you.
