I've had first hand experience with this type of woman. This is the type of girl that loves to "catch" a guy, and then show him how powerful she is. Usually soon after that, she gets bored with him and moves on.
This type of woman is usually very insecure about her own beauty, womanhood, and life in general. If you do see past her evil techniques, then you might have a chance at keeping her. The chances are though she has more deep-rooted problems which she can deal with only with the help of a doctor.
Just stick to my motto, "Women are the devil."
