When it comes to relationships, women usually move with logic and not love. They are not superficial. They have very specific preferences and once those preferences are being met, they can easily put their feelings aside to make the most practical decision that works in their favour.
They are wired and they have been conditioned to choose a man that performs his duties well over one they love, and that is why relationships only work when a man is more in love with a woman than when she loves him more.
