This is a joke right? Sakura was busy fangirling over the cool and mysterious jerk while completely ignoring Naruto. The poor guy had to watch her pathetic behavior.
He didn't give up on Sasuke who made multiple attempts on his life, his teammates lives, tried to steal his dream, made claims to destroy Konoha, made claims to take over Konoha and much more. Yet he gave up on Sakura because she was "fangirling and completely ignoring Naruto" as you put it.
And no, I'm not blaming Naruto for any of this stuff. What I will say is that Kishi butchered Naruto and Sakura. There's no need to play the blame game with these characters.
