Aqua Sun - Virgo rising - Sagittarius Moon - Pisces Venus - Capricorn Mars
If you broke up then why would she miss you? If the relationship came to an end then there are no feelings left or they are being hidden because of the hurt. Either way she wont tell you because she probably wants to move on.
Why do you want her to miss you and still care? It seems like you are having trouble letting her go and she senses that. So she doesnt want to complicate things and rather talk about your friends instead.
