I started as NH fan, but I understood very fast it never stood a chance. The little bits that made me think it could have been a possibility were anime filler. When you read the manga it's very clear she's just a weird girl he didn't like much, though he latter started to respect her a little. The relationships is all about prop talks.
The NH fandom was really what turned me off from the pairing, seeing those people so sure to be right and acting mean to alternative ships. You have no idea the kitten us SasuHinaers got before Karin was introduced.
What really nails the coffin is that Hinata's introduction in shippuden ended up with a fainting, which cemented nothing good could come out of their casual interactions. Meanwhile Sakura were acting all flirty with him at the begining of shippuden and Yamato started to hint at NaruSaku too.
When the Kushina talk came it just confirmed what I already knew, the "weird" girl Hinata never was a serious competition to Sakura.
