There's pretty much three categories of women. There are those that actually like you, there are those who like what you can do for them and there are those who don't like you at all.
The women that like you for you are the ones who you never really have to put much effort into getting their time. They do what it takes to spend time with you. They hang on to your every word. They are always friendly to you.
Those that like what you can do for them are the women that MAY act friendly, but only after some condition is met. Like maybe they weren't feeling you before and wasn't giving you any time, but as soon as they see you rolling in a fly car, all of a sudden they dig you. These are the gold diggers and fame jockers. These are the leeches. This is the category of woman who will pay you time, but will require you to take her to dinner, take her to the movies, entertain her, buy her gifts, etc. Once you cease doing that, she ceases dealing with you... hence, she likes what you can do for her. This kind of girl, you do not deal with.
The last category is obvious enough. This is the brand of women that just ain't feeling you. This is where a lot of men get stashed into the friend category, because they keep doing anything to win the affections of the type of women that ain't feeling them. The woman isn't really feeling you, she doesn't want to use you, but she doesn't want to hurt your feelings, so she stuffs you in the buddy category. When coming across this kind of woman, just learn to cut your losses and keep it pushing.
The key to winning in this game is to learn to deal with women that like you for you and that want to be caught. As you notice, it's a COMPLETELY different interaction between these categories of women. In the first category, the woman is mad easy to talk to, you will have a lot of fun with her, and everything is smooth. In the second category, it can be a lot of fun, but it is an illusion. She is cool with you until she gets what she wants. This second and third category is where a lot of men can really get caught up and get played because they aren't watchful.
When a woman doesn't like you, and thus has no feelings for you, she can justify doing just about anything to you if that is what is in her moral make-up. This is why I see the second category of the one who likes what you can do for them as the absolute worst to deal with... They can feign interest in you, but once they got what they want or if you won't give it to them, you become completely expendable in their eyes.
ALWAYS deal with the first category of woman. This will make things 10,000 times easier. If you have to bedazzle a woman, do these magic tricks, buy her dinners or all sorts of trickery to maintain her interest, then she isn't for you. Learning how to successfully classify women will save you a ton of time and sanity in the future.
