GAH! Is it just us women who flip out when our POIs don't respond or contact us? I get so angry with myself wondering if I were a man, would I be the same? Why can't we just let go and let it be?
For the most part it is women, but not all women. In many areas women outnumber men so men generally have an easier time with relationships and can pick/choose among many, plus jump to the next flavor when the first one turns sour. It's the way that nature intended. More women are born than men in order to make sure the species does not die out. Male babies miscarry more than females as well.
China is one of the biggest continents that do not have this problem, due to the law of only one child per household because of over population and favoring males over females. Men outnumber women and the women have the upper hand to a degree in what they get to pick/choose.
