formation of relationship

• the biological assumption of neurotransmitters can be used to describe how romantic relationships are formed.
• the sex hormones testosterone and oestrogen are primarily the cause of "lust" behaviour in the initial first attraction stage in romantic relationships.
• after this, the attraction phase takes place in which partners become obsessive and spend a lot of time thinking about one another. This obsessive behaviour is caused by the neurotransmitter serotonin being depleted.
• in the final stage of long-term trust in a romantic relationship, vasopressin and oxytocin levels are shown to increase when in love.
• oxytocin is particularly important in terms of human bonding and increasing trust and loyalty
