You know this goes beyond just familial expectations and fatherly disappointment. The CPR scene was a symbolical callback to the commitment Kushina had for Minato, but the messenger's own projected ideals and thoughts. It was Sakura that ultimately supported Naruto through his darkest hour. Sakura who continually resuscitated him while repeating to herself unwaveringly how she would not allow him to die while his dream of becoming Hokage was so close to fruition - it was right before their eyes, not just Naruto's alone.
What does Hinata know of Naruto's conflicts or dreams? Nothing. She's only ever harboured these romantic sentiments for his never give up attitude, not for the boy's own interests or conflicts or relationships.
In a way, Naruto not only betrayed his parents' trust, but Itachi's as well. He forsook the woman who had given him life and supported him for his own dreams - not some fanciful invention - including his desire to become Hokage.
