" Without sufficient pull inwards, towards the sanctity of the couple relationship, the relationship can become lost, powerless, and vulnerable to many divisive factors including other people. Without sufficient pull outwards, into the world, we can become so selfish and inward-looking as a couple that we stop growing. The relationship can become stale and the people involved can become suffocated with their own togetherness. "
― Donna Goddard , Love's Longing (Love and Devotion, #3)
