constant bickering ... am I wrong???

I need some unbiased thoughts here because if I tell my friends and/or family they'll side with me and that's not what I want. I want honest opinions ladies! 
My husband and I are constantly arguing. About anything. He never believes me and is always questioning anything in conversation. Even the dumbest things like hurting my hand - he says I'm overexagerating and "did it really hurt that bad?" Wtf. I can't even talk about he dumbest things like that without him trying to prove me wrong. It's so dumb but am I over sensitive? 
Another example - I asked him to put some boxes in a specific place and he's looking right at me and sets them down where he wanted to. I naturally started yelling because  I just don't understand why he wouldn't just put them where I asked him to and suddenly it's my fault and he wasn't going to do it if he didn't understand why. Shouldn't me just asking be enough?! 
I'm seriously depressed about this and it's just 2 dumb examples from the past 12 hours. 
What am I doing wrong?
