According to Osho, the calendar length of a relationship has no inherent sanctity; what matters is whether two people use the time to awaken love, awareness, and freedom in each other. A year can be a laboratory: watchfulness, honesty, playfulness, and non-possessiveness reveal whether love ripens or withers. If it nourishes your being, stay; if it becomes bondage or habit, bless it and move on.
A year only matters if it helps you both grow more loving, aware, and free; if not, thank it and let go.
