well ... id say. you stop pursuing a girl.. after the first 20 minutes of meeting her..
Assuming that you created enough attraction, gave her DHV, negged her a bit so she looks for your validation...
But if youre not sure about that happening, then you ask yourself, was she giving me lots of IOIs??.... Did she look attracted to me??... When i met her, was I negging her enough that she was looking for my validation??... DId she look crazy about me??.... then if those are a YES.. you continue.. call her.. lets say... 3 or 4 days after you met her... but CALL HER... make the first contact direct, dont use txt msg... better call her... if she doesnt answer.. now you can try sending her a msg the next day... if she doesnt answer... leave it like that.. and move on...
maybe, contrary to what all-american suggested... id say... if the first atempt on calling her, failed. then leave it like that... the desire of a result may have insidious effects in your game, inner frame and inner game.....
PLus,, youre a pre-selected man, remember?.. if she didnt take the bait.. some1 else will.. besides youre a high social demand person and dont have time to waste calling her until she answers... .
but try it using both aproaches
..see what works best for you
...take care
