"A relationship is like a perennial plant; both become more resilient as they learn how to balance the contradictions required for growth. Under the earth, the plant needs sturdy roots. Above, it needs to be able to dance on the wind. It needs sunshine and rain. It needs attention and space. It changes with the seasons, dying back and growing up over and over again. And when it outgrows its pot or plot, it needs to move." [source : https://www.estherperel.com/blog]
