A pattern I noticed after receiving offers from more than 30 women: “The less pleasant a woman is, the higher her asking price tends to be.”

Is this a straightforward chain of cause and effect—“unpleasant attitude → bad personality → self-centered thinking → higher demands”—or is it more of a feedback loop: “(the woman is) unpleasant → (she) dislikes me → (from her perspective, as compensation for having to put up with me) her asking price goes up”? I feel like I’ve encountered both types. Are there any male members who have noticed a similar “pattern”?
