The idea that being in love has a limited shelf life of about 18 months is a myth; couples can sustain being in love indefinitely. Research indicates that maintaining a vibrant love life hinges on simple, consistent behaviors. Key factors include expressing love daily, showing affection publicly, giving compliments, cuddling regularly, prioritizing weekly romantic dates, and continuing to engage in fun and adventurous activities together. Notably, many couples approaching therapy report that the element of fun has diminished in their relationship, suggesting that laughter and play are essential ingredients for lasting love.
