But I'm Different Now lyrics

Picked you up and let you down and I never said a word? But I'm different now and I'm glad that you're my girl Mess you 'round and upset you I Hurt you most of all? But I'm different now and I'm glad that you're my girl Fun lasts for seconds, love lasts for days but But you can't have both? And I'm different now but I'm glad that you're my girl Because I know I done some things That I should never have done But I'm different now and I'm glad that you're my girl
