Well while I agree that they never said "Cloud never loved Aerith." but if he did or not is really up to how you played the game. There's no solid evidence that he actually DID love Aerith... nada, none, zero, zip, zilch, sorry but try again later. You could maybe make a case for Clerith if you played the game that way, but if you take out all optional evidence, you really have nothing for Clerith.
