To me this is about a destructive relationship, two people desperately clinging onto each other from force of habit or something that was once love but has slowly become resentment, they've destroyed all elements of each other's lives and friendships "when all our friends are dead" and just left empty skulls and bones and the remnants of themselves clinging on together. They have literally sucked the life out of each other therefore this loveless relationship feels like they're buried underground and repressed for eternity, never being free of one another because that's how it's always been.
