Naruto, personally, hasn't been developed romantically.
Does the guy want a family? He has not been shown in the paternal light, nor has he been portrayed as the husbandly type, either. His concept of romance is still very child-like. Like I said - a girlfriend is someone cute and attractive who goes to eat ramen with him regularly while telling everyone she's his girlfriend.
He really hasn't demonstrated a romantic understanding beyond that of a gradeschooler.
There's no confusion there. There's an internal conflict - but there's no confusion. She recognizes that Naruto is a great person and any girl should be happy to have him.
But she doesn't want him that way. Never has, and never will. He doesn't make her panties wet, and she's not interested in a guy that can't give her that thrill.
Never was, and never will be. Just looking at it with common sense tells you that Sakura has been out of the picture for a romantic pairing with Naruto since he became 'the fluffer' in agreeing to bring Sasuke back for her.

Those two threads I built almost as a series. Though I could go through it even more exhaustively and with more bits of information that have been found since then - but Sakura doesn't even begin to fit into the picture of the plot. She's a character that isn't.
It's clear that Kishimoto's thinking on the plot has included Hinata for a very long time, and that she's intended to play an integral role in the plot since the beginning.
By comparison - Sakura is kind of stuck on there as a tag-along. She's done nothing to really advance the plot (well, one can argue that her defeat of Sasori was involved in the plot... but by that same token, so was Konohamaru's defeating the Naraka Path). Kishimoto has, really, not put nearly as much focus on her as he has on Hinata.
He can say what he wants in interviews, but the patterns in his writing betray his biases. Sakura may be a headline character - but she's a tag-along for the plot... a plot that Hinata has been integrated deeply into since close to the inception of the story.
