It's intersting that you see her character that way, because I see her really differently (plus she's long been one of my favorite characters in the series).
Including the anime's embellishment mini-arcs (the kid flashback stuff), it actually paints a rather different image of Hinata than the rather cliche moments she has. She's the natural heir to the Hyuuga, which puts her in a position where she's expected to outperform everyone else, in addition to being treated royally, and being forcably distanced herself from everyone else. The anime gets into Hinata being curious about her not being able to interact with Naruto really early on, and noticing that he's different, but seeing a positive side of him that everyone else ignores. That helps to give a background on why she's the one who seems to notice positive qualities about him before he manages to properly prove himself to everyone else, and give reason to why she's always whispering encouragement, or like the recent chapter where she trusts him because of the look in his eyes.
The other arc that ties into this is the fact that she's living in the shadow of what her father expects of her. As Neji attempts to fight against his own destiny, that shadow of expectation that her father expects her to exceed only grows larger. Then, Hanabi (who, like Neji's view of the main House, sees Hinata as a goal to surpass), manages to best her for leadership of the clan. She's shunned for not living up to others' expectations in a less direct, but similiar way to Naruto's wish for acknowledgement, which (aside from her crush) is a lot of why she adopts Naruto's Nindo as her own - it's a methodology that she wants to be like, but hasn't been able to achieve. Since Naruto's gone from a bit of a goof up into a hero and sufficiently surpassed her now too, she still has the same goal of what she wants to achieve, but there's a slight difference. Unlike Neji & Hanabi, she sees Naruto as someone that she doesn't want to surpass, but just wants to catch up to (which is also what is being referred to in her quote this chapter). It's all part of the arc of her attempting to outgrow the shadow of expectations that she's constantly been under, but in her own way, and also get close to Naruto at the same time.
From the romantic side, I've never really thought of her as stalkerish, just
super introverted. She's not using her Byakugan to spy on him, or obsessing over little things that he does in a weird way like the early Sasuke-crushes did. She's only hiding and looking at him from behind things becuase she's SO easily emotionally overwhelmed, and can't find the courage to directly approach him. The few times she does, she continually tries to talk to him and have normal (even single word) conversations with him, like during the Chuunin exams, but just can't get her own emotions under control. She even faints when going to say goodbye to him. While this is cut back when she matures in Shippuden, she's still very held back. The only moments that the two of them really share anything together are usually when things get dangerous, and she is put into a place where she's forced to (potentially permanently) either deny or embrace her emotions - and she always embraces them, and overcomes her nervousness and fights against Yahiko/Pain. Since Naruto's really still new to the concept of even his own parents loving him, let alone the admiration that he's receiving, I think it'd be odd for him to directly confront Hinata about it (especially given the whole Sakura/Sasuke false revelation).Whenever they DO talk, they're not in the real presence of a larger group setting, but also not really alone, and it seems to be the only time that they seem to address their emotions at all. To me that's the biggest reason why Naruto doesn't respond about the Pain battle until they're both briefly alone in combat again. This is indirectly touched on when he confronts his inner Darkness, because he's still caught off guard by people asking for his autograph, let alone the idea that Hinata loves him.
In a lot of ways, it reminds me of the recent portrayl of Kushina & Minato's early relationship, but with the roles reversed. Minato's always around a lot, half-spying on her, but rather than not talking, Kushina's always being overly aggressive towards him and cutting him off. They don't really have a real conversation with each other, let alone about their feelings until they're caught up into a dangerous / life-threatening scenario.
Anyhow, tl;dr - she's just introverted, not a stalker, and wants to follow Naruto's Nindo as much as she wants to date him.
