Listen, If Naruto wanted her, and he wanted to be with her he had every opportunity to SAY IT instead of looking on like a sick, kicked puppy. Sometimes acting selfish, getting jealous CAN be a good thing. Instead he takes on the messiah complex and he loses.
Thats his own fault. We won't know how Sakura would have reacte IF he'd confessed because HE NEVER HAD THE GUMPTION TO DO IT.
The fact of the matter is even if he confessed and Sakura refused him it would have been on her, but he didn't so its on him.
She knows that he loves her...She knows that Naruto suffers from loving her...and look how she acted in those two chapters: 693 and 699
She tried to move on, but she couldn't. She has an unconditional love for Sasuke. How can he confess, seriously...
