I also see it as the death of a relationship, but I feel it more as if it's about the fear of its real end.
The love was once so strong that maybe they hope that staying together they could love each other again, searching for a sign by the other that something is changing in positive, but it's just like continuing the agony and fueling the bad feelings that are replacing the love.
They're both afraid to be the one to say "stop, it's over", 'cause they're aware that after that there will be no coming back.
