This is probably a stretch, but i think this song is about childhood friends drifting apart, possibly due to Jamie's or this boy's struggle to accept his own bisexuality.
"trying to not to cry in front of your older brother"
Sounds like the boy's need to prove his masculinity. The whole image of the friend walking away suggests his homophobic abandoment of Jamie.
