I was just thinking about this a lot the past few days. Love for women is just their realization that you are higher SMV than her, likely the highest SMV guy she will get, and the nonexistence of any severe disqualifiers. Ie. Ask a Chad how many girls have told him they have loved him even within a few hours of meeting him.
It is basically meaningless except as a marker of your SMV. If your SMV drops, that "love" disappears with it.
Women are cruel, harsh, and transactional. They measure your worth based primarily on genetic factors, and if you make the cut they will "love" you.
