I got the impression that the song was about how one treats their lover. As in, he doesn't treat her right...he gives her knots...he knows this, but now he wants to take them out before she leaves.
"She asked me to work on that knot
Now I've been at that
coalface some time
I've been trying to untie that knot"
That tells me that she asked him to work on something...behavior for example...now he is really trying hard to fix himself (or fix the knot that is bugging her) to make her happy.
I feel it's about taking away the stress he's caused before she cant handle it anymore.
