I love beautiful women. I really do. I practically thank them for existing- you make the world a better place for just adding to its physical beauty! It's superficial, but it is also human- no matter what your personal preferences or ideals, everybody is drawn towards and enamored by aesthetics.
Thus, women who are perceived as very physically attractive - I'm not talking about just being "above average" in terms of the modern Western standard of beauty (I realize that beauty is in the eye of the beholder, and I'm approaching this from the standpoint of general Western society), but the "bombshells," the 8-10s of the world- are mollycoddled.
There are many such women who have great personalities, are very cool to be around, and are highly intelligent. But they can't help it- society still treats them differently for their external appearance. In life and in the workplace, people hesitate to point out their mistakes. Sure, some women have horrible bosses, but the majority of their interactions with people are still instilled with a kind of awe. People rarely reprimand them harshly and often are very soft about how they approach them about their mistakes.
This creates a situation where many of these "bombshells," at least those who have grown up all their lives recognizing their beauty and its effects on other people, have trouble facing up to their own mistakes. I have quite a few friends who have dated such women, and encountered times where the girl, although really a good person, simply cannot accept that they need to bear responsibility for wrongdoing.
In one instance, one of my friends was in a relationship with a very attractive brunette, who we'll just call Jennifer. Now Jennifer is a dedicated student and a fun girl, very smart and hardworking. But when they broke up, she blamed everything on him. Although he was not consciously trying to do anything wrong, she turned around and painted him as a very bad guy. Every single thing wrong with the relationship was due to him, and he was just trying to "use" her from the start.
This guy is definitely a very caring and genuine individual, and it bothers him to this day that a person who he so valued and esteemed could view him that way.
That was a very extreme example of how some beautiful-beyond-the-norm women cannot handle responsibility. Simply put: Attractive women often cannot handle people calling them out on their bullshit.
It's not really their fault; society has conditioned them to not have to correct their mistakes.
Does this mean everybody should just avoid beautiful women? Hell no! My advice is simply to not be afraid, like most guys (or girls) who have dated her in the past, to point out when she's wrong. Don't be an ass about it, but if she's blatantly wrong and denying it, then calmly and kindly talk to her about it. But if you don't set the precedence early on, or if she simply can't handle the truth, then there will be problems further on.
You may not believe it now, but there is one maxim that holds: "For every beautiful woman that a million guys want to fuck, I'll show you a man tired of fucking her."
