I am not into her character, how her character's main purpose is Naruto Uzumaki. She is literally there to bare his children. She has made little progress in any fields that don't revolve him. She has made no intent to end the clan's strife and slavery of the branch family.
Actually, Hinata's main goal was to get recognition from her father. The only reason that she liked Naruto was because they were both seeking recognition. She is just as involved in her family as she is with Naruto. She performed the Senbon 1000 sparring thing in her family and she trains with them. Hinata also spends a lot of time cooking as a passion and dancing such as by the waterfall. Hinata wants to build a good relationship with everyone and is generally concerned about everyone, just moreso with Naruto because he relates to her. Hinata doesn't cook just for Naruto, dance just for Naruto, Get recognition of her family just for Naruto. She does those things for herself. You are just blinded by the times that she has shown her admiration and/or love of/for Naruto. She is a heroine of character and if you read closely you would realize that Hinata's nindo is the same as Naruto's because they want the same thing. Another noteworthy thing is the fact that Hinata looked after Kurenai more when she was pregnantthan Shikamaru did. That wasn't for Naruto! Hinata is not a shallow 1-D character. I have huge respect for her and I don't appreciate you bashing. She lives for more than Naruto, it's just that the other parts about Hinata would bore readers because they don't advance the plot, that's why they're revealed in the fillers. If Hinata was a main character, then we would know more about he life away from Naruto. But because she isn't , there isn't much reason to show it. However, Kishi did say that they would be some Hyuga development so maybe soon we'll start actually getting more of Hinata's char away from Naruto.
