I think that this song means all of the above with a few additions. It's definitely about a failing and broken relationship, but I think it has to do with a failing relationship in which the girl is starting new relationships and slowly forgetting about the guy. I don't think it even neccessarily has to be a girlfriend (it probably is though). These are the lines that suggest this meaning:
"Eight feet undercover, don’t forget that I'm here
Warm secrets under covers with new friends
and your holiday lovers"
I don't know though. As it is with most Northstar songs, it's probably dealing with a lot of different things.
