I definitely think this song is about a woman having an affair with someone (the narrator). I got that the first time I heard it, with the lines: "Does your husband know (the way) That the sunshine gleams from your wedding ring?" Husband + wedding ring automatically made me think affair, and the rest of the song made me think that the narrator was completely and hopelessly in love with the woman.
