Just Another Day in Mommy's House

So here’s the thing, ever since my wife and I started our little DDLG kink dynamic a couple years ago, things have been pretty good. She calls me “Mommy” and plays along with it, which is kinda funny if you think about how strict we both are in real life. But that’s beside the point. The actual issue? Well, today she was extra sassy, like, really testing my patience. I had just come back from work and needed to chill for a bit before dinner. She wanted to play some of those games that require me to “discipline” her, which usually involves light spanking and lots of cuddling afterwards. But today? Today it felt like she was trying to push every single button I have. I told her nicely a few times to calm down, but you know how it is when someone’s in the mood for a little drama. So after one particularly cheeky comment about my cooking (it's not that bad), I lost my cool and did something I never thought I would, snapped and actually yelled at her, which was supposed to be the ultimate taboo between us. Now, looking back on it, she’s pretty upset. She doesn’t want me to yell or show any real anger while playing this role. And honestly, when you really think about it, who can blame her? It feels weird reflecting on it now because I don’t normally lose my temper at all, this isn't how I roll outside of our dynamic either. The question is, did I cross a line by losing control like that? Is this something she’ll forgive? Or is it the end of our little game? So here’s my question to anyone who might read this: Am I being too hard on myself for just one bad moment? Is there room in adult relationships for moments where things get a bit intense, even if they’re not meant to be that way at all times? Please let me know what you think. I need some advice because honestly, I'm not sure how to make this right.
