i think this song is about how breaking up with his girlfriend is like driving him to drink, "you're the drink in my hand" because she he left he can't get her out of his head. And i don't think that he broke up with her, it seems like it was some kind of almost mutual agreement, but still not sure if they're doing the right thing kind of deal. As we can see he's regreting leaving and "can't wait to get back home" I think he's confused on whether he should follow his heart or his career, as his only dream is to be with her, but his job is calling him to be away from her, and that kind of stress can definitely lead to drinking
