Oh yeah, yeah
  Mmm
  Mmm, mm-hmm
  Oh, oh
  Damn
    Must've been C-R-A-Z-Y
  We got all out of sync and went bye bye bye
  Not too long ago, you was mine mine mine
  Seems like yesterday (yesterday)
  Ninety on the freeway, pushin' my ride
  Heard you got him game (?) and I'm losin' my mind
  Ask myself the question, why why why
  Why'd I let you get away from me?
    Well you must've been, thinkin' I'm a jerk
  Cryin' out to God, tryin' to make this work
  Girl you must've been, stayin' with a fool
  Loving somebody that could be so cruel
  Well you must've been, packin' your bags
  Silly of me, I couldn't see the red flag
  Girl I'm sure that (sure that) you must have been
  Sick and tired of me
    Must've been tired of the jewels I bought
  You must've been bored with the cars you got
  I must've gave you everything you want
  But you only wanted love (wanted love)
  I must've been too damn blind to see
  I thought you wanted much too much of me
  Now I'm rollin' down this one way street
  And you're all I'm thinkin' of, baby, mmm
    Well you must've been, thinkin' I'm a jerk
  Cryin' to God, tryin' to make this thing work
  Girl you must've been, stayin' with a fool
  Loving somebody that could treat you so cruel
  Well you must've been, packin' your bags
  Silly of me, I couldn't see the red flag
  Girl I'm sure that (sure that) you must have been
  Sick and tired of me
    You must have been
  The very one I was supposed to spend
  My money, my life, my lover, my wife
  Girl I know you were right
  You must have been
  The very one I was supposed to spend
  Spend the rest of my life
  Now it cuts like a knife, I know
    Well you must've been, thinkin' I'm a jerk
  Cryin' to God, tryin' to make this thing work
  Girl you must've been, stayin' with a fool
  Loving somebody who would treat you so cruel
  Well you must've been, packin' all your bags
  Silly of me, couldn't see the red flag
  Girl I'm sure that (sure that) you must have been
  You must have, you must have, you must have
    (Well you must've been)
  Now I know I don't have, mm, an invitation
  (Girl you must've been)
  And everybody in this church is gonna be mad at me
  (Well you must've been)
  I can't let you say "I do," that's why I'm down on my knee
  (Girl I'm sure that you must have been)
  The preacher said, speak now, speak now or forever hold my peace
    Well you must've been (I know, I know, I know, I know, I know)
  Girl you must've been (I know, I know, I know, I know, I know)
