The "Confident Jerk" gets the girl mythos comes from men who are just plain jerks but believe themselves to be nice. When confronted with rejection from women, they rely on this mythos to displace blame for their own behavior onto the woman instead.

"It's not me, it's a lack of judgement in her gender!"

That very thought in and of itself defines one as a jerk, imo. Of course people like and prefer to be around nice people.
