Lyric discussion by CeeJai 

I think he's talking about a girl who plays with men but won't settle down. I think "old enough to change your name" means she's old enough to settle down & get married. I've always felt that the woman in this song was just strong willed and wanted to be free, not that she meant to be a tramp, the feeling of the song is too gentle for the speaker to be angry at her.
