she fell deeply in love with someone who couldn't handle what was happening aka, falling in love - and ran away in fear - she in turn sank deeply into misery from not being able to love - the person eventually came back and reached out to her, and she tries to love to liberate them (from their fear) - 'trust me one more time, i can only try - let me pull you free' = free to love
