If I could share my takes on your questions,Also are we just never going to address her resolution in Remake? Where would she get the impression Cloud would think he fell in love with her? When exactly did she realize it's not real? Why was her future self dream visiting him at that point if this is their goodbye? They have to refer to it eventually too. Or at least they should.
1. “Are we just never going to address her resolution in Remake?” - I think we do get closure for Aerith’s resolution in the church date for Rebirth. Aerith tells Cloud, “At least I know now, where you and I stand I mean.” Depending on affinity, Players can either interpret this scene as Aerith accepting that Cloud sees her as a friend or Aerith is happy that he, at the very least, also wanted to spend more time with her.
2. “Where would she get the impression Cloud would think he fell in love with her?” - I don’t think this line is necessarily referring to a specific moment when/if Cloud fell in love with Aerith but I think it’s more of a warning for Cloud to not to get too attached because she wants to soften the blow when she dies (since Aerith in the Aerith resolution is theorized to be a version of herself aware that she dies). It’s also why I think during their church goodbye she tells him, ”Whatever happens, it’s not your fault.”
3. “When exactly did she realize it's not real?” - Similarily to #2, I don’t think this line is necessarily referring to a specific moment when/if Aerith realizes that Cloud’s attraction to her isn’t real. Rather, I think it’s more of Aerith hinting towards Cloud about his false memories and SOLDIER persona. In Rebirth, she says something similar during their GS Date about wanting to ”meet the real him” to his obvious confusion.
4. “Why was her future self dream visiting him at that point if this is their goodbye?“ - The obvious answer is that the devs really loved delving into Aerith’s prophetic side that was aware of her fate in Remake XD however, was it ever explicitly confirmed that the future Aerith in her Resolution was Advent Children Aerith? If not, the Remake Chapter 14 Aerith seems waaaaay more similar to Rebirth Chapter 14 Aerith. This would also line up better since the way Aerith talks about the future, Cloud, and their relationship in these sections of the game are very very similar.
I might change my mind if more evidence is brought up, but currently, I’m getting the sense that the Church Date in Rebirth IS THE CONCLUSION to Aerith’s Resolution in Remake. Just food for thought.
