This may be a reach, but I think he's remembering a previous love (perhap a recent break-up). He's hurt and he's just trying to get on with his daily tasks, maybe his office-job. Also, he's trying to tell himself to move on, and to forget about love and get his mind off things.
The bluebird reference reminds him of this girl, maybe because its graceful and beautiful. One day they might fall in love again, but for now, he needs to force himself to think love "isn't sacred."
