ok the hard and fast rule is to DJ the girl until she asks you
the thing is, from my experience, is that you must also be aware of the type of girl you are DJ'ing. I DJ'ed a girl for ages, it drove her crazy, but she never brought up the relationship thing (which i was cool with), but when she stopped letting me kiss her / didn't respond, it started to piss me off.
in the end, it turns out that all she was waiting for, was for me to mention somethings. the reason for this, is that she was the shy type of girl that didn't want to assume anything, and her values basically meant she would try to refrain from kissing a guy unless he asked her out first.
needless to say, i DJ'ed her for ages, and ignored her for a week / played cold games with her, and she was really upset and mopey over me. eventually i told her to come over, and i asked her out cuz i could see how mopey and disraught she was. she later told me that she wouldn't have made a mve if i had continued to ignore / DJ her, despite her interest in me.
so KNOW what the girl you're chasing is like. some girls would be more direct than the one i'm currently dating
it is good to DJ constantly to keep her on her toes, but some women will not speak no matter what. SO kNOW if she's a HOE and not giving it up to u cuz she has no interest ---- or if she's interested, but she's just too shy and wants the guy to make the first move.
