The song Last Letter is performed by Marty Robbins .
Why do you treat me as if I were only a friend
What have I done that has made you so distant and cold
Sometimes I wonder if you'll be contented again
Will you be happy when you are withered and old
I cannot offer you diamonds and mansions so fine
I cannot offer you clothes your young body crave
But if you'll say that you long to forever be mine
Think of the heartaches the tears and the sorrows you'll save
While I am writing this letter I think of the past
And of the promises that you are breaking so free
But to this cruel world I'll soon say my farewell at last
I will be gone when you'll read this last letter from me
When you are lonely and tired of another man's gold
When you are lonely remember this letter my own
But don't try to answer though I've suffered anguish untold
If you don't love me I just wish you would leave me alone
