"If she is not interested, LJBFing her is not going to change her mind. It may boost your challenge level to her, but if she's not interested you should stop wasting time with her."
first off, this isnt a tactic to change her mind. its not a tactic designed to make you more desirable to her...
its a tactic to be used in conjunction with asking for her number, and setting up dates. to neutralize the massage of "i want you" that these two things always suggest. basically, its a safety device, if she aint interested in you, it prevents her from putting up barriers which can grow when an uninterested women learns your interested.
this gives you a good chance to get a date, where as, if her barriers were up, it would be very very hard to set up a date.
and just becuase a girl isnt interested in you when your asking for her number doesnt mean you wont have a chance to make her interested. LIKE ON A DATE. i think its foolish to NEXT her just becuase shes not interested the first time you met her.
incase you havent learned, there are ways to make women want you bad, and all you need is is some privacy to spend with her(the date) in order to do so.
this tactic just helps your chances of getting a date with an uninterested women if you will.
and for the other question about when to stop. first of, your not "acting" like her friend. your just playing it cool, and LJBFing her by specifically pointing out to her that she would mak a friend. and it has the desired psychological effect on her.
your not putting on an act or anything. and you only use it when you extract a phone number, and when your talking to her on the phone, setting up the date. AS BOTH THOSE THINGS SUGGEST "I WANT YOU" and that can often deter an uninterested women from going on a date with you, let alone talk to you on the phone.
once the date begins, your ljbfing stops. you got her where you want her. and you got plenty of time to work on her and make her want you bad. thats the strategy basically.
