How to keep a woman interest in you?

Hey men, okay so it seems that a lot of women like men that plays hard to get but they loose interest as soon as you reciprocate you interest, I know this is because they really don’t really like you they just like your attention so as soon you start liking them they back off, because you are not really a challenge for them, I’m not saying that all women are like this but a lot are, so guys how do you deal to keep this women attention but expressing your interest at the same time? It’s there a way to archive it? I mean maybe be even harder to get so as soon as you show the interest they see you as a regard or maybe wait till she confesses or the hell I know, any man who have experience in this kind of game that can give me an answer?
