But if she did know, that makes her a huge bitch for not telling Zack's parents when they ask.
I think she did know Zack was dead, but that's just it: that's the only thing she does know. It's not like she told Elmyra a lot about her husband's death, just that his spirit had wanted to see her.
She wouldn't be able to tell Zack's parents where he died (except maybe approximately), how he died (on-duty? by accident? murder?), what he was doing for the past five years, if he was given proper rites... All of these are things a person might reasonably want to know about a loved one's death. Chances are good the circumstances surrounding Zack were among the "...many things" Aerith says she wants to learn when the party leaves Midgar.
She couldn't even have told them how she knows without sounding like a lunatic. Remember, Elmyra didn't believe Aerith when she told her, so why would Zack's parents? They were looking for news that their son was OK, not news of his death, and very likely would have balked at that. And Aerith would know that, because she knows how Elmyra reacted... and how she reacted herself. (Considering her hang-up about Zack in the game, if she did know about his death, she probably did NOT take it well at all when she heard.)
Even if she could convince them, there is no way to tell them about Zack's death and not raise other fears and insecurities, possibly even guilt (what was their son going through for five years that he never got word to them and died? why didn't they try harder to track him down?) short of lying about the circumstances. So... she doesn't. She may just be too upset to think straight about it, considering how she left the house. She may honestly believe that with how things stand, it's better for them to be able to think that Zack is a negligent son--but is doing OK--than deal with that. After all, when Cloud talks to her in Gongaga, she seems to be convincing herself that Zack disappeared taking off with another girl. Tifabelle, that quote you posted? Aerith's hoping he had the affair instead
Is she in denial about his death, or just not talking about it and trying to explain away his disappearance beforehand? Honestly, I see it as her being hurt over what she knows, uncertain over what she doesn't, and not wanting to spread either feeling around. But oh yes is there some unclear writing in the game with Aerith.
