Lyric discussion by cybermachiavellin 

Its pretty staright forward to me. Glycerine is used in food photography to preserve and enhance the look of food, its a preservative. Now you don't want to eat the stuff after you use it, so when I shot something I really wanted to eat, I misted it with water. So he is saying he wants the relationship to stay the same forever, to always be good. "Don't let the days go by". In the lyrics he alludes to trouble in the relationship, but every relationship has its faults and he admits he could have been better at holding up his bargain. It sounds like a guy on the cusp of losing the best relationship he has had.

@cybermachiavellin I LOVE this meaning….it’s obviously the tone of the song when you really listen! You’re smart to dissect the “glycerine” aspect.
