There is a sentence from Johnny Cash's Wikipedia page with a very strange structure:
At the July 5, 2003, concert (his last public performance), before singing "Ring of Fire", Cash read a statement that he had written shortly before taking the stage:
The spirit of June Carter overshadows me tonight with the love she had for me and the love I have for her. We connect somewhere between here and Heaven. She came down for a short visit, I guess, from Heaven to visit with me tonight to give me courage and inspiration like she always has. She's never been one for me except courage and inspiration. I thank God for June Carter. I love her with all my heart.
Does this sentence mean "She has always only been my courage and inspiration", or "She has always been my courage and inspiration (and probably some other things)"? And can anyone explain more about this structure?
