I think Sandy441988 is on track with some added thoughts. The chorus repeats the confusion we can get into when relationships are not working. Wanting to go it again wanting to light up the dark thinking we are not being holier than thou, with the halo on the side and not on our heads. However we are often so self deceptive and until we are to change ourselves we are doomed to have the cycle repeat.
