Not necessarily, because unlike Aerith, she actually gets to unveil the real Cloud. And the real Cloud are free to spend their lives together, as Aerith is a witness to discovering the real Cloud in the Lifestream. Another thing is the fact that Aerith suspected Cloud of being Zack, while Tifa suspected of Cloud not being who he really was, especially because he was garbing on all this crap about being SOLDIER. Tifa knows who the real Cloud is. Aerith doesn't know the real Cloud, and although she
suspects that he's not the real Cloud (because of her Cetra abilities), those suspicions directly go to Zack. And like Tiff said, if Maiden is canon, we know that Aerith admits herself that she doesn't know who the real Cloud is.
Lol, maybe you can invite some people here? It probably gets tiring after awhile.
