I love Brent, and I've used - and still use - his "method" (which he claims is not a method) extensively. It makes seduction effortless (when it works). It makes you try less. It makes you more outcome independent (which actually may require a bit of discipline sometimes, because with a hot woman it can be hard to not lean in).
I've gotten it to a point where women give me those begging looks. Like, I don't think I'm traditionally handsome, but just by employing the techniques of outcome independence, women start to act strange around them, such that you can just take their hand, bring them outside, pin them against the wall, make out, and then smile and simply tell her: "Come."
Questions:
Honest question: Why would care? A guy who really gets Brent wouldn't worry about that, and instead focus on his own life and goals.
The "chat" (I'm assuming texting from online dating here, which is not by forte, so correct me if I'm wrong, but) should establish at least some comfort first, basic get-to-know things. And then, when commonalities and comfort is established, make an invitation to meet up in real life (presumably for sex, but in Brent's world, sex is assumed so don't even worry about it).
If she accepts the invitation: Cool. Make the plans. But if she doesn't take the invitation, then shoot the ball into her corner, so to speak. Tell her something along the lines of "That's cool. Just shoot me a text when you want to meet." And that's that. Move on with your life.
Honestly, though - and this might hit you hard, but - most of your questions are not really in the spirit of Brent. They circle around your need to analyse women, in order to understand her better, so you can game her. Brent doesn't care about any of that. Outside, perhaps, on a purely scientific or philosophical pursuit for its own sake, that is really outside the realm of seduction.
It's generally a bad idea without establishing at least a bit of commonality and comfort with her. From Brent's perspective, that doesn't mean that you can't flirt or be sexy or even vulgar, if you do it for your own amusement. But most of his talks are geared towards those men who are tired of all the games and all the hard work. His advice circle around using zero effort, and still getting super hot women. Moreover, you'll probably notice that when you start to care much less about outcomes or "gaming" her, then you'll start to attract the really hot girl. Like, it's strange, but they'll eat out of your hand, they'll beg to suck your dick even. It's hard to explain. You won't get there until you truly stop caring, and when you truly take back the power in the interaction. I sometimes think women have a sixth sense for desperation. OTOH when you master this, don't be surprised if women jump at you, try to kiss you, try to kiss you even if her bf is in the room - whenever he looks away (I've experienced some crazy shit once I got this).
Again, dude. Sorry. This will probably hurt, but the question itself seems needy. She wants to feel that you're the man and that she has to work for you, but here's some bad news: you can't fake it - not in Brent's world, anyway. But afaik my own experience, you can't fake it in any world, though you can mimic certain things and hope it gives you reactions. But then you're working for it, which defeats the purpose of Brent again. So... You actually have to be that man.
Well, go on! You can do it!
