It's called "Out of the Picture" by the Robins and was written in 1956. It can be found on "The Best of the Robins" at Amazon.com.
words are: You left me, you said we're through, I'm all alone, lost without you, what shall I do? Out of the picture, out of the frame and now when you see me nothing's the same. Your lips are kissing somebody new, I'm out of the picture, out of the view!
Hope that helps!
