When it comes to understanding someone's feelings non-verbally, it's important to keep in mind that subtle cues can be subjective and may not always provide a clear answer. However, here are a few non-verbal cues that may indicate if a woman has feelings for you:

1. Body Language: Observe her body language when she is around you. If she often leans in towards you, maintains eye contact, or faces you directly with open body posture, these can be signs that she is interested in you.

2. Personal Touch: Pay attention to how she reacts to physical contact. Casual touches, such as a gentle brush of the arm or playful nudges, may indicate comfort and attraction.

3. Mirroring: Notice if she mirrors your actions and gestures. This can be a subconscious sign that she is trying to connect and build rapport with you.

4. Increased Attention: If she seems genuinely interested in your life, asks questions, and remembers details about your conversations, it could be a sign that she cares about you.

5. Pupil Dilation: When we are attracted to someone, our pupils tend to dilate. Although this can be a subtle sign, it can indicate a heightened level of interest.

Remember that non-verbal cues should be interpreted cautiously, and it's always better to have open and honest communication to clarify your feelings and intentions. If you want to know for sure, consider having a conversation with her to openly express your emotions and discuss your relationship.
