I liked your long story.
However, there is a fundamental problem with PUA:
- they are unattractive men (in the primary sense of the word: they did not manage to attract a mate)
- they resort to manipulative tactics (that is the essence of the PUA teaching)
- and their aim is to use others to their advantage.
They are a bit like the time-sharing agents roaming some beaches and living from having unsuspecting tourists signing a predatory contract in a language they don’t understand. That is inherently wrong.
In addition, they approach women on the street. We learn here that many women feel distressed by that. So that behavior is also inappropriate. Men should not address women on the street, point.
