Not everyone will show their cards right away, and there might be a good reason why she's hiding her feelings from you. Maybe she's uncertain about your feelings for her. Maybe you're good friends and she doesn't want to make things weird. Maybe she's in a relationship and doesn't want to stir the boat.
“If she's nodding and smiling, but not really contributing to the conversation, she's just being polite,” says Tessina. “If she's leaning back and not really engaging you, she's just being polite. If she's glancing around, she's just being polite.”
