As is quite obvious, the song is about a one-night stand and the remorse he feels, not only for doing it, but also for not pursing the girl afterwards and throwing her aside almost as a fallback girl for a "rainy day" that he waited to long on even though he really did like her ("never thought it'd hurt so bad to see you with another....").
Whether Thiessen is painting a metaphorical or realistic personal experience is beyond our knowledge.
On a deeper level however, it is one more piece in the two-album story that Matthew Thiessen and Relient K have been painting through their 2009 "Forget And Not Slow Down" and their 2013 "Collapsible Lung." As this is part of the second part of the story (which is much more dark and dwells on the dysfunctional side of romance), I highly encourage you to check out Stephen C. Shutters' in-depth look at the album as a whole so you get a firm grasp on the over-arching message of the release: http://stephenshutters.com/post/54525347408/collapsiblelungreview
