The document discusses the three stages of love: lust, attraction, and attachment. Lust is driven by sex hormones like testosterone and estrogen. Attraction involves neurotransmitters in the brain like dopamine, norepinephrine, and serotonin and is described as the "love struck" phase. Attachment occurs when the couple decides to continue the relationship and make long-term commitments, which can lead to raising a family together. Special hormones like oxytocin and vasopressin are secreted during attachment to promote intimacy and long-term relationships.
