Given the example (from a British novel, The Secret Intensity of Everyday Life)
Well what did I expect who said it would be easy? I will not let this defeat me. I will persist.
Is the first sentence a complete sentence? If yes, then does who take a role of relative pronoun? Can it be separated from the antecedent, I?
Or are these two sentences and the writer intentionally omits a punctuation mark to get the protagonist’s rapid thinking across?
