I am trying to find an artist/song name - here are some of the lyrics:
"One step forward & two steps back
no matter what I do your always mad
& I can't change your mind
maybe were not meant to be"

THEORY OF A DEAD MAN - NOT MEANT TO BE LYRICS (http://www.metrolyrics.com/not-meant-to-be-lyrics-theory-of-a-deadman.html)

Also sounds like it could be Opposites Attract Lyrics by Paula Abdul (http://www.lyricsdepot.com/paula-abdul/opposites-attract.html)
