I'm going to hold you to that....
I'm not sure what fan translations you're reading but I'm pretty confident in hitoshura's work which has surpassed some of the official translations by far. In regards to your point, I'm glad you acknowledge that C/A doesn't hold a candle in terms of canon towards C/A. We're making strides here.
Their "tid bits" mean something, yes. They mean they care about each other. But how does that automatically cross over into the romantic sphere? Is it not entirely possible for them to have an emotional and caring connection that is platonic and still loving? Where is this romance and partnership?
No one's saying Aerith isn't important to Cloud. It's the whole "Aerith is Cloud's lover/past lover" that is being questioned. Aerith was important to Cloud but if you're going to try to shoehorn his feelings of guilt and sadness into feelings of romantic love, you need proof of said romantic love. Of course Cloud isn't going to forget Aerith. But how is that automatically, romance?
So a fun date, where they don't even touch or kiss, is indicative of romance? Not only that, but they only knew each other for 2 weeks at most.
And its funny you bring up Cait Sith, since the FFVII Ultimania Omega explicitly states his fortunes are mostly wrong.
No one is saying Cloud doesn't love Aerith. Clearly he feels love for her. However, we're talking about romantic love. Cloud clearly cares about her and loves her like a close friend and important person who made an impact on his life. But Tifa's love is something different and romantic. That's the point.
I'm glad we're finally starting to make some headway here.
