Contrary to popular belief "No Woman, No Cry" was not a song written about getting over a girl. They are the words Bob Marley sings to his woman to assure her that he will return. Basically saying, No woman, don't cry. In the song the man is a travelling minstrel telling his woman he will come back for her.
"So dry your eyes I say, and while I'm gone
everything is going to be alright
everything is going to be alright now
no woman no cry, no woman no cry"
