This is either a suicidal song, or a break up song. "So, this isn't where you thought we'd be, You explained. And now, you leave it up to me."
The above lines seem to make it look like a Breakup song. "Farewell, my love. Say "hello" to state lines, separate our whole life. Farewell, my love. Say "goodbye" to girlfriend, you'll text her from the road." These lines seem to be kinda suicidal, saying that the guy has had enough of the stuff the girl is doing, and is walking out of the relationship. Idk, it's my opinion.
