Nikki has ran away from a bad home and is now experiencing the seedy and dangerous side of homelessness. She sells herself to the narrator who treats her well and she feels comforted by him so she tells him "stay with me". As the song progresses the narrator falls for the beautiful girl and when she feels it is time to go home he is the one who says "stay with me"
I get this meaning by the reversal of the lyrics for the last part of the song
