He wants to be able to be with Naruto and have his attention. He wants a normal family. Because truly, it seems like naruto is barely there. He is always too busy. And having a clone to play around with Bolt isn't enough. It's not going to fill up that emptiness he has.
And he was just sad about how hinata put in the work to fix his lunch but he couldn't wait a couple more seconds to get it. That is all.
On the cool, he not really a jerk. He's just a boy who needs his Dad. Yes, hinata most likely showers him with love but there is nothing like a father/son bonding time.
