Actually, come to think of it, A LOT of BB's arguments are not only in bad faith, but contradicted by the sources we provide here at the Lifestream.
From
Tifa's Profile, regarding her "complicated feelings"
Compilation Check
A close friend as well as rival?
The complicated emotions she feels towards Aerith.
「Both of them share feelings for Cloud 」 — Tifa was close to Aerith, who can also be called a love rival. With that point in mind, they were also good friends. Nevertheless, it is not hard to imagine that she carries complex feelings as a woman toward Aerith, who had built up a special bond with Cloud that was different from Tifa’s.
Tifa’s complicated feelings continue even in AC, two years after Aerith had departed the world.
This was due to the fact that Cloud, succumbing to the notion that Aerith’s death was his fault and condemning himself, construed that Denzel was “the child which Aerith brought here” and took care of him. In addition, Cloud had also gone away to the church that Aerith had been in. The thing which she is unable to hide in her irritation towards Cloud is the fact that he isn’t merely dragging the past around, but because that reason might perhaps be related to Aerith.
Now, the word jealous isn't in this segment. It's not anywhere in the profile. What is emphasized is CLOUD'S GUILT. You know, that thing what he deals with.
Now, mind, it does mention peevish feelings at Cloud and Aerith developing their own world in front of her, but it also mentions that Cherishing Aerith is her true feeling.
To sum up, Tifa is not described as Jealous of Aerith. Not in so many words. But Aerith, in Maiden who travels the planet, is explicitly jealous, or more accurately, envious, of Tifa getting to live together with Cloud.
We also get this, in re: Childhood friend
"I want to see Cloud — Marlene’s honest words, which reflected what Tifa felt in her own heart, caused her to smile. The present Tifa isn’t just Cloud’s childhood friend, but also the mother of the ‘family’ they were forming in Edge. "
Not just the childhood friend, and "of the family they were forming" the bit about family they formed is not unique to that profile. It's in the reunion files, too.
Anyways, in her
CC profile, we get this description.
The only woman who knows Cloud’s past.
In FF7, Tifa is the only one who knows Cloud’s childhood, and furthermore, she holds the key to people involved in the story of Nibelheim’s burning down, which is also depicted in CC. She and Cloud came to realize their feelings for each other in the end of the story, and live together in AC and DC.
"They realize their feelings for each other, and live together in AC and DC" is pretty blatant. Especially given it's for a game in which she's a side character in a single chapter.
Lastly, about the original ending of AC. Cloud is driving home to spend a day with Tifa and the Kids. We know that from the making of movie. Aerith is watching over him, but he's not searching for her and she's not hoping to meet him. She's just there to make sure he's fine.
