Although I agree with many interpretations in terms of finding someone when you were at your worst, and then at theirs, I can't help but think this could also be about passing into the afterlife and reuniting with a loved one. Church bells ringing could be a funeral, and just being lost and damaged and they find you. Or it could also be just that random time when a loved one has passed, and you're at a fork in the road, or going through a terrible time, and they find you in your darkest place and you hear their voice and they guide you through it.
