I think it's about the demise of a relationship. It sounds as if the last time they were at home together they were in the beginning stages - and being torn to pieces - by the realization that they were breaking up.
Now time has passed, she's no longer waiting or crying. Although it saddens him, he understands. He even wishes her well. They've done their best to adjust to the fact that they are no longer together. It was a tough blow, but now they are just digging through the rubble of who they were and trying to move on in the process.
