<human>: The title is kind of confusing to put, but I'll give an example.

Earlier today when he came home from work I was switching the netflix on the ps3 from the big one to the small one (switching the hdmi cord) and was switching it back to the channel for his computer. Instead of seeing what I was doing, or asking, he spat out, "Don't turn off my tv!" I replied, "I wasn't turning it off." 

I saw a clip for Shark Tank on Hulu and it skipped them showing the product, he fussed "why did you fast forward it?" Instead of asking if I did. When I explained that it was only a clip he said,"Well why are you watching it then?" I responded, "Because it said Million dollar deal and I wanted to see it. I didn't know they weren't going to show the product." He then gets frustrated says, "Why do you get so defensive? All I did was ask?" 

I explained to him that I feel like he's attacking me and that I would like for him to ask me instead of state things without even asking if that's what I was doing. Now he is kinda giving me the silent treatment/hardly talking to me.

What can I do to relay this to him? Am I the one in the wrong?

Can you condense the text into a few key points?
<bot>: Boyfriend makes demanding statements that are usually wrong instead of asking me or just seeing what I'm doing and then gets fruatrated that I'm being 'defensive' when I explain or validate whatever I really was doing.
