The Unbreakable Chain Lyrics

Wow, heard this song for the first time recently. What a heart wrenching song.

It's basically about a mother who chose to (or had to) give up their child some "30 years ago" then seeks and gets reunified with their child, expressing the long held connection that is 'an unbreakable chain'. Could be more symbolic than that, but that's it at face value.

What I don't quite get is why the song finishes with the lyrics "you've broken the unbreakable chain" ... that mode of usage doesn't seem to quite fit with the rest of the song, food for thought.
