Lyric discussion by BrokenWing18 

I agree that it's about a guy, presumably Johnny telling Jenny that they need to get out, and even though everyone wants them to come back home- or various reasons, they aren't (Maybe more specifically Johnny is already set on not coming back).

I think the song is also him not only convincing her, he's also reassuring her that he is irrevocably in love with her and that as long as they're together everything will be okay. I pull this from the idea of a "Bulletproof Heart", even if he is shot, he will love her, if he is killed the love that he holds in his heart won't fade. I also pull that idea from :"I ain't gonna be the one left standing/You ain't gonna be the one left standing/We ain't gonna be the ones left standing" It's like saying we'll be alright, no matter what.
