It definitely sounds like a relationship that was very passionate but ended badly without any type of closure on either end and he's writing this song as sort of an apology/an "I miss you and I'm sorry". It sounds like he just wants to go back to the way things were before they fell apart. Whatever the case, it's a beautiful song and my favorite from the new album :)
