Searching for the right adjective to describe someone. She a mix of shy and deliberately obtuse in a slightly flirtatious way. Very calculated. Is purposely vague for the sake of trying to drum up interest. Not in a negative-connotation but more so in an friendly annoying way. Imagine someone coming to you to let you know they have terribly bad news with a smile on their face and then when you inquire about it - rather than tell you they change the topic to something totally different with the hopes that you continue to press for more information.
"Obtuse" seemed too unintentional and not calculated, "disingenuous" - was my closest fit but seemed too cold, "coy" - too playful... can't quite put my finger on it.
EX: Don't take her constant vagueness too personally, she's just being (insert adj).
EX: She is so ( ). Every time I try to peel back the layers on her we end up on a whole new tangent.
