Well, as screwed up as it may seem, and although it's been discussed to death, women hate to be made the most important person in a relationship, hate making decisions, etc.
And if you think this is just some pick-up guru BS, let me give you some examples:
1) I know this couple, the guy is a wuss, the girl is not that great looking but has been pampered to death by her family, spoon-fed everything all her life. This guy would do everything for her, and the more he did it, the nastier she got with him, to the point where she would PHYSICALLY ASSAULT him (kick him, punch him) in front of other people for something as small as having a cigarette! And when he bought an apartment for himself and her, the broad actually made him paint all the walls in a nasty, fugly dark-pink, which everybody laughs at, but she's the boss.
2) I teach English to this big time business guy who works in logistics, the kind of guy who everybody bows before, and he was telling how he and his wife were going shopping and he wanted her to make the decision with regard to which mall they should go. After a series of "I don't care, whichever you choose is fine!" and "just make a gd decision woman!", they got into a huge fight which almost ended in divorce.
It almost gets to a point where I'm wondering whether you can actually have a successful relationship with a woman without actually being a jerk to her and occassionally (well, often) saying something insulting to her.
It's so illogical and counterintuitive that I don't know how many guys would be able to figure it out on their own without the benefit of having read the material that all or most of the people on this board have read.
A good example is given by David DeAngelo on one of his DVD programs:
Let's say that one day you get in your car to drive to work, but it suddenly turns out that when you hit the gas pedal, the car stops and when you hit the breaks, the car speeds up. It's so non-sensical that many people would refuse to accept it and keep hitting the gas pedal to speed up, instead of accepting that - for whatever reason - it's the other way around now.
Anyway, hope that helps.
