I always compare the dating scene to job interviews.
Look at it like this....you go for an interview and some you just KNOW were a total flop so you wouldn't even bother chase it up, some you're not so sure about and then there's those that you're almost certain you got the job. Now in my experience, the usual protocol is that if you haven't heard anything from the employer within a week, the chances are you weren't successful. There was one job I really wanted and couldn't keep my mind off it. I even called the agency three weeks later and asked if there was any feedback, only to be told they hired another candidate (them b*stards never even had the professional courtesy to send a letter or e-mail to say I didn't get the job). I learned after that that if I don't get any feedback at all after a week or two max, then it's dead in the water. This can even happen when you THINK you did well.
Then there's those interviews where you may not even be so sure, OR you get on so well with the employer that you hear back from them immediately (this happened at my current job) and they give you an offer
even if they have other candidates they are seeing who are interested (you get the analogy?).
It's the same with broads. If they really like you, they ain't gonna be doing this hard-to-get b.s., or this "oh I'm busy on Fridays, lemme get back to you", or not hitting you back up straight away. Even if they lose your number (and that's almost never the case they just aren't interested) they will do like that old Calicoe vs Young Ill "who is this nikka?" - they'll wikipedia, ask jeeves, wssh, find somebody who knows somebody who knows you lol - search it in the youtube and you'll get the joke. Trust me they'll let you know they're interested no matter what their schedules are.
If they haven't responded after the first text, then it's a no go. I know deep down it stings and that ether burns, but you'll get over it and eventually even forget about the chick. Until then, don't give them the satisfaction of playing their little games. They KNOW what they're doing when they don't respond and they love it. I've seen them boast about that shyt online so none of it is by accident.
Be just as quick to send them to the bushes as if they were faulty products on a conveyor belt and keep it moving and you'll be good. In the meantime work on yourself and eventually the right chick will come along. Out of the billions of women on the planet, you're bound to come across one who is the perfect match for you.
