That doesn't help that much though. Here's a question, what do you think she thinks along that line.
A) He doesn't care...My love...just keeps fading...
B) He doesn't care...Team 7...isn't the same...
That's the problem. We don't know if it's about Team 7. We don't know if it's about her love. It's vague to know what is the main reason behind it.
Man, you put me in a fix XD. Okay I have to reconsider why I think that way. But since you have asked that question, I'll tell what I think and why is it so. The moments she shared with Naruto, everyone's opinion on Sakura's feelings, I agree with all of them. Now, it seems as if she sub-consciously loves Naruto and not consciously because she seems to shrouded by, 'But I love Sasuke kun' thing. This cannot be the reality as we all know. Maybe she did have feelings for Sasuke but presently she just 'convinces' herself that she still trusts Sasuke. I'll give you an example. When Sai had asked Sakura about her opinions on Sasuke coming back, what she replied was 'Its good Sasuke kun came back and....I trust him'. Now Sai cannot be lying about her fake smile since he was once fooled by it and fooling him second time in case of smiles was next to impossible. So since, Sai cannot lie it does mean Sakura was lying. Following thought might have flashed Sakura's mind, 'Sasuke kun is back on our side. But I think he has ulteriour motives. Can I...trust him? No, I should trust him, he does not have ulterior motives'. Even she knows that's not true but she just convinces herself that what she is thinking is not true. I am not saying it is like this, but it CAN be like this. In the same way, maybe she knows she doesn't love Sasuke anymore but she just keeps convincing herself that she still loves Sasuke and that is why continues to get affected by him when she shouldn't. And because she keeps convincing herself she cannot move on, but apprently true feelings surface in one way or the other in her case, the dire situations. When she is put in a dire situation, her true feelings for Naruto surface and apparently she doesn't know it. It just happens naturally because obviously she has feelings for Naruto. This goes in line with her expressions we got when Yamato said 'Sakura just by looking at you I can tell that you really...'. Sakura knew right what Yamato had to say and her expressions were that of an astonished girl. That's why I say in dire situations, her true feelings come up and apparently they come out 'naturally' and she is not aware of them and this is exactly why she still thinks she loves Sasuke and keeps convincing herself for that. Not saying it is this way, but it can be that way since what I can do is just estimate behind the curtain scenario. I don't know for sure, but based on a similar experience, I say this.
