That women who are 'fuck yes' are in chameleon mode. And that a woman can be as fickle to be all for you one second and drop you like a hat like another.

So as they gravitate towards women who appear to be besotted with them, they fail to see that they are only being viewed as, "What can this new man offer me?" And she'll easily replace you and be all fuck yes for another man if he offered more.

Women view men as a business deal. Enthusiasm comes from the potential prospect of maximizing attention and resources only.
