Is the road to love littered by the bones of others who were mysteriously undone?

Question

In Gordon Lightfoot's song RACE AMONG THE RUINS, he says:

The road to love is littered
By the bones of other ones
Who by the magic of the moment
Were mysteriously undone

Answer 1

He's Gordon Lightfoot!!! I know he'd never lie about a thing like that, so YES.

Answer 2

The road to love is littered
By the bones of other ones
Who by the magic of the moment
Were mysteriously undone
You try to understand it
But you never seem to find
Any kind of freedom comin' clean
Is just another state of mind.

Even seeing the whole verse it puzzles me what he is trying to say.
Perhaps he means for every person that do find love, there are those who haven't, and those who have loved and lost.
