The brain is hardwired to help us fall out of love, and researchers call this process "mate ejection." When we fall out of love, the reward centers of the brain (that release dopamine and cause pleasure) stop being stimulated. Falling out of love is also a process of forgetting old habits and connections, which can cause changes in the release patterns of hormones and neurotransmitters associated with pleasure, reward, and bonding. The "out-of-love" brain starts to rewire and stops seeing the partner as a pathway to happiness and excitement. This also suggests that couples must engage in fun, exciting, and new experiences to get the dopamine and norepinephrine surges to reward their brains and create a feedback loop to reinforce feelings of love and attachment to the other person.
