<human>: Can you give me a shortened version of the text?

Everything was fine. With our daughter staying at grandma's house, we were planning on going to dinner. On the drive to the restaurant, we got on the topic of her job. After we were seated at the restaurant, placed our drink orders, received our drinks, and placed our dinner orders, the subject of conversation hadn't changed. She was still going on about the goings-on at work and I started to space out. I must've responded in a way which didn't make sense, because she responded with "You're not even listening to me." "Sorry," I said "I was just looking at the dessert menu. You were saying...?" She came back with "Whatever. I'm done." Those we're the last words she spoke to me. I tried to apologize, she wouldn't talk to me. She even started crying. We ate our meals in silence and didn't speak a word to each other all night. We slept in separate beds last night. (Which occasionally happens anyway, for comfort reasons). And we both went to work this morning... I feel like a piece of shit.
I know how silly this must seem on the surface. But, we are not immature teenagers. We've been together for 8 years. This type of thing very rarely happens. Especially over something (seemingly) so petty. There almost has to be more to this situation that I am not seeing.
I really don't know where to go from here. She's a very stubborn woman, and I don't want to dig this hole any deeper.
<bot>: My wife is super pissed and not talking to me after I wasn't paying attention during a lengthy conversation about her job.
