If Cloud loved Aerith, it was not in a romantic way; after she died, it was a reverence of a holy being. Aerith had been elevated to a level of being a goddess to Cloud.
Well, that's what I think anyways
And besides, the main thing that can't be ignored is that Aerith DIDN'T love Cloud. At first she was intrigued because he reminded her so much of Zack (her true love), but she only cared for him as a friend.
I should know better though; this is a club about Cloud/Tifa, not so much about trampling on Cloud/Aerith; even though I absolutely LOATH (yes, I used the word "loath") the idea of that pairing.
I wonder what a kid conceived by Cloud and Tifa would look like...
