Where did you get the ideea I am NaruSaku? Stop making assumptions BEFORE you actually look into something.
So, let's make things clear. Is not a wish of mine. I could care less how they end, as long as they're happy, BUT, let's revise some things you said.
That she doesn't care about him, right?
1. Please tell me, who was the first one to support his dream to become a Hokage?

2. Who was the one that OVER TIME changed her feelings for Naruto as she realised he is indeed a great guy?

3. It is even observed by others how gentle she is with him...

4. Not to mention the minute she saw Sai speaking about Sasuke and that Naruto was hurted by that, she took the matters into her own hands.

6. Who was the one who, knowing clearly that could die, put Naruto's health above ANYTHING, even her love for Sasuke, as Naruto was in great danger?

7. Plus, not to mention that she clearly develops feelings for her as others have seen it...

Not going into much more detail than that.
I am not ignoring Hinata's feeling for him. As I told you, to me is the same, as long as they end up happily ever after. But this thing is Naruto's choice. If Sakura's the one he loves, there's nothing we can do about that.
Plus, I would see Hinata supporting him in the end if he doesn't chose her, because she's a great kind-hearted girl.
The same it would happen with Sakura if she finally 100% gets in love with him and he chooses Hinata.
They both want what's the best for him.
