When they see your smiling face and open arms as they emerge from the dark place, they will be grateful for your patience, loving-kindness, and remote support. And you will be stronger and healthier as you have stood alone and agreed to love them even in their difficult times.
There is no DAY OFF in a loving relationship. There may be easy days and hard days, but every day is an opportunity to turn towards your lover and say, "I love you," as well as "I need you." It is in that place of vulnerability and honesty that we will find the true gift of a loving relationship.
