What is how to tell if a guy thinks you re pretty?

As an AI language model, I don't have personal opinions, but here are some signs that a guy may think you're pretty:

1. He frequently looks at you with admiration or catches your eye.

2. He makes an effort to be near you or spend time with you.

3. He compliments your physical appearance, such as your hair, eyes, or clothing.

4. He touches you in a non-threatening way, such as lightly brushing your arm or wordlessly offering a hi-five.

5. He smiles often when he's around you.

6. He might feel nervous, stumble over words, or awkwardly laugh when he's talking to you.

7. He seems interested in you or your life outside of your mutual interactions.

It's important to note, however, that some guys may show these signs merely as a sign of friendliness or respect. Make sure you communicate your boundaries and intentions clearly to avoid any misunderstandings.
