What is why is it so awkward between me and him?

Without specific details about the situation between you and this person, I can only offer some general reasons why interactions might feel awkward. Consider the following possibilities:

1. Lack of Communication: Misunderstandings or lack of clear communication can create tension or awkwardness. Ensure that both of you are on the same page about your intentions and feelings.

2. Different Expectations: If you have different expectations about your relationship or interactions, it might lead to discomfort. Discussing what you both want or envision can help alleviate this.

3. Past Experiences: Any unresolved issues or negative experiences from the past can contribute to awkwardness.

4. Nervousness: Sometimes, being nervous or anxious around someone, particularly if you want to make a good impression, can lead to awkwardness.

5. Social Dynamics: Changes in social dynamics, such as shifts in friendship groups, roles, or interests, can create tension.

6. Personal Differences: Differences in personality, interests, or communication styles can lead to misunderstandings or awkward moments.

7. Mixed Signals: If either of you is sending mixed signals, it can create confusion and uneasy interactions.

8. External Stressors: Outside stressors, such as work, school, or personal issues, can affect how you interact with others and might lead to awkward situations.

To address the awkwardness, consider having an open and honest conversation with the person. It might help to address any underlying issues and improve your interactions moving forward.
