But I'm Different Now

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
