Female flakiness is perhaps the most widespread of unattractive dating habits men have to deal with when interacting with women. Therefore, when a man comes across a woman who keeps her word no matter what, she immediately stands out amongst her peers. Add to this the fact that habitual flaky behaviour means that a woman is more concerned with how she feels at the expense of others. Having such a low level of interest in how her actions affect those around her, she illustrates a deep lack of empathy. And in the eyes of a mature, masculine man, a woman with a lack of empathy represents all that is opposed to mature womanhood.
