What is he gets nervous and avoids me?

Dealing with someone who gets nervous and avoids you can be challenging, and it's important to approach the situation with sensitivity and understanding. Here are a few things to consider:

1. Understand the Reasons: There could be various reasons why someone might feel nervous around you or choose to avoid you. It could be due to social anxiety, shyness, past experiences, or feeling intimidated. It's important not to jump to conclusions without understanding their perspective.

2. Approach with Empathy: If you believe that this person is avoiding you due to nervousness, try to be empathetic. Consider whether there is anything in your interactions that might unintentionally contribute to their discomfort.

3. Open Communication: If you are comfortable doing so, consider initiating a conversation in a non-confrontational way. You might say something like, "I've noticed that you seem a bit uncomfortable around me. Is there anything I can do to make things better?"

4. Give Them Space: Sometimes giving the person space and time is the best course of action. Allow them to approach you when they're ready. Pressuring them might increase their anxiety.

5. Adjust Your Behavior: Reflect on your own behavior and see if there are changes you can make to make interactions more comfortable. This might mean adjusting your tone, body language, or manner of conversation.

6. Seek Mutual Activities: Engaging in group activities or projects might ease the tension as it shifts the focus off one-on-one interactions, allowing the person to feel more at ease.

7. Professional Help: If you believe the nervousness stems from deeper issues such as social anxiety, it might be helpful for the person to speak with a mental health professional for guidance.

Remember that while you can try to make the situation more comfortable, you can't force someone to react a certain way. Patience and understanding are key in these situations.
