So when is the cutoff between a STR and a LTR. The LTR one won't work if the relationship is too new because she will be projecting all these false traits on her guy. Basically viewing him "as the best". If she still is in the moonlight faze the STR technique might not work.
Also, would this work on a girl you f-closed in the past but were never in an actual relationship with? I ask this because she would already know somewhat, how you would be as a bf, since you have already spent some time with her. Thanks allot Xavier.
