Read Song of Songs (Song of Solomon) 2 today

This chapter includes a strong sense of anticipation or anxiously awaiting the lover’s arrival.
It makes me wonder about the relationship between those who have been married for a long time. Do they still maintain the anticipation for the other to arrive? Or have they become, as someone once said, “old married people”? Sure it is comfortable, but is there any fire?
And from the spiritual standpoint, do I approach worship, or Bible study, or personal devotion time with this sense of anticipation? Is there any fire in my time with God?
