Most of this is 100% straight up projection, and the reason you should never take relationship advice from women.
Step 1: Play hard to get: Bullshit. Women love guys who play hard to get because they wonder why their powers don't work on them. Only guys who've had sex with 100 women by the age of 12 like girls who play hard to get.
Step 4: Jealousy: Bullshit. If some girl I'm with is aggressively flirting with other guys it tells me she's a *****. I'll tell her what I think and be on my way.
The rest is stuff everyone except the most die-hard pussy knows about women.
