I enjoy some hard to get but I also need some hints dropped that I'm on the right path...say stuff that is flirty and make sure to have some physical contact with him...not to much but every now in then reach out and grab his hand when talking or sit close to him and rub against him with your body, not in a over the top grinding way but just in a brushing up against you kind of way. Surrendering some of your personal space lets a guy know that you are at least somewhat comfortable with him physically and most women who are comfortable with a man physically also like him to a certain extent emotionally.
I like women who play hard to get, I figure if all it takes is a smile and a compliment to get to the prize then probably a lot of guys have been there before.
