If you don't think women care about your interest level you're not living in the real world. Players do so well because they feign interest. They treat her like she is the only girl in the world even when they are fvcking other women
Most of these PUA tactics seem to be geared toward creating distance between you and the girl. Don't text them, don't talk to them, make them miss you, don't GAF about them. That may be great advice for the guy whose problem is that he just gets way too gushy and overboard over these chicks, but that just has never been my problem. I mean it was when I was really young and a green as grass beginner, but I really think that not overdoing it is the first lesson you learn anyway.
A lot of players (as you say), go the complete opposite way. They love up on them like they're totally enthralled. Deesade made a post the other day how he makes them think they might have a chance for a relationship. That's all feigning interest, and not this creating distance stuff. The creating distance stuff just leads to things like Neil not seeing his dream girl for eight weeks or whatever it was (although she was acting up on him too).
Certainly after you bang the girl, you shouldn't have to keep finding ways of tricking her into liking you. Go be with her, have fun.
When you are high value and successful you aren't trying to "be alpha". You just treat people like human beings and have fun. It's not that complicated.
Yeah, this is part of giving value instead of taking value. Instead of being so caught up in ignoring the girl for fear she might think you have some interest in her and be repulsed by you. Or even worse, that she might find out what you're really like, and bam the game is up then.
I really think there are a lot of different approaches that can work, and that you should find one that fits your personality. So text, don't text, do whatever you want, but do it because YOU want to, not because Corey Wayne told you to.
You mentioned Facebook. I won't have a Facebook account myself, not my thing. But I can certainly see how some people might use it to their advantage, for sure.
