Speaking objectively and I mean really objetively here:
I always thought Hinata was the Red herring of Naruto's romantic life, she had very little interactions with him, her confession was never adressed, neither mentioned again in the manga, her arc own arc I thought initially was about her becoming stronger and someone who can walk besides Naruto, even as her own flipping wife however, we see that she will never go against him even if she believes that his absence is problematic for her children, now hear me out I personally never liked Hinata during the manga run but is funny how she became a housewife (negating all of the stuff she said about wanting to become stronger) and not only that, she prefers to takes Naruto side even when she herselfs knows her own flipping kids are unhappy with the situation.
She was, and also honestly not even that. She originally was just a girl that befriends Naruto so we be interested in his first round fight in the tournament. Once she did that her role in Naruto was complete, she was then just a tertiary background character. But then the new editors told Kishi of her popularity and constantly tried to push her into more scene. Some even thought that that hinata should replace Sakura as the love interest as well as the heroine, and some thought that her confession did just that. Kishimoto resisted at first but in the end gave up and did what they wanted. Now he stuck being the editor of the sequel because they fear the if he isn't involve that Boruto would completely collapse.
