What is so wrong about falling in love two times. If Naruto does end up with Sakura, i wouldn't think of Naruto as the second guy. Tbh, I've fallen in love twice two. As a matter of fact, I'm still with that guy today. Does this mean that I'm just using him as a replacement? I don't get whats so bad about it? You make it seem like a huge deal. My father has fallen in love twice, and he's still with my mother to this day. You're insulting everyone out there who has fallen in love twice. (Atleast your insulting me.)
I guess lot of people just want it to be as romantic as possible. Readers expect unrealistic thing such as characters only able to love one person in their life. Kishimoto's writting doesn't help, since, so far, not a single character has been allowed to move on, not even poor Sakura and Karin, neither Lee, Hinata, Obito or Ino and of course not Naruto. Hence the apparent cul-de-sac the romance subplot is into.
Damn, that's one of the thing that irritates me the most. I had high expectation for Karin when she showed sign of moving on, which made me believe there were hope for Hinata, Lee and Ino to not end up alone with 45 cats with a mini shrine of Naruto/Sakura/Sasuke in their rooms... But Kishi made sure to give us more of "Karin loves Sasuke so much BS". Could he at least abstained to have him stabbing her and use Suigetsu as a punching ball instead as he isn't really attached to Sasuke, so that I could still support her feelings.
At least for Sakura, there is Naruto's magical MC charisma to eventually cure her from her self-destructive love for Sasuke. The other characters don't have that chance.
Seriously Kishi, why not keep it simple (one girl = one boy) and drama free (no murder attempts and emotional abuses pls) ? 
Positive point is that NS looks a lot more better than the rest of the non dead ships (as Kishi killed the few decent non NS OTP).
