"We couldn't mend glass into sand."
Glass is made up OF sand, naturally, so mending glass into sand would do the reverse - break up. The song is about a relationship, but the two involved don't know when to give up. They "meet every night in broken hope" in an attempt to work out their problems, but they fail miserably. I think the writer is placing most of the fault on the girl, saying she turns around everything he says, including "goodbye," to mean something else and doesn't really ALLOW him to leave. Only if he gives up talking and just runs, can he get out.
