When anything including love becomes familiar, that excitement slips away and new things draw our attention. When we become infatuated with someone, we start to idealize them. They suddenly become the perfection of femininity or masculinity. And it's like, okay, this person actually is a human being full of imperfections. It goes from the extra personal dopamine to the peri personal here and now. The dopaminergic, extra personal, idealized love is passionate love. Having kind of love is called companion at love.
