Women are raised from a young age to think relationships and their romantic life will be like a Disney cartoon. From the time they're little girls they expect Prince Charming will come along at some point and sweep them off their feet. Well, the world doesn't work that way. That being said, there's no reason you can't be a woman's Prince Charming. However, you must first understand that who he truly was isn't what most people would expect. The truth is actually something that goes against the grain of most Disneyesque ideals of romantic love and chivalry.
The Prince Charming Theory is a combination of essentially two factors:
Preselection - An evolutionary shortcut, or tool, humans developed to determine from afar if a person is high value. If others look upon someone favorably we are typically draw to them and/or wonder what makes them valuable. In females this wonder sparks preliminary attraction. The effect of preselection, like having women crawling all over you, makes it a hell of a lot easier to open up other women later on. In some cases women will begin to open you!
Perceived Value - This is when a high value male chooses a woman. The effect this has on women is at the heart of the Prince Charming Theory: When a high value male with lots of choice regarding sexual/relationship partners chooses a particular woman then she is perceived as the female with the most value of any of those he could choose from. This makes a woman feel special and has the benefit of making her value, cherish, and respect the relationship so much more than if she merely chose the man. This is intrinsically different from the traditional paradigm of women choosing men and is why women will often chase a man, or otherwise tolerate abuse or otherwise bad treatment, by men that seem disinterested or that have 3 other women on speed dial.
I don't generally agree with Disneyesque ideals of romance, or any relationship advice given by mainstream media as it's usually terrible and chock full of social programming. But when it comes to Prince Charming, he was the ultimate version of what men should strive to be if they want control over their relationships and want women to chase him. He was preselected, had options, and he chose the women he wished to interact with. Furthermore, those women who he chose felt special because he chose them. That's the secret sauce of Prince Charming Theory.
When you reach that point it's important to note that qualifying women is integral to keeping them. If not, they will have worthiness issues.
