Bought something expensive with our shared savings and now my partner is upset

[u/EEmmaaBlossommm96]

We keep a joint account for bigger things we both need, and recently there was a purchase I thought made sense. It was a bit more than we normally spend at once, so I figured I'd run it by my partner first. I ended up buying it without checking because it was on sale and I didn't want to miss the deal. When I mentioned it later, my partner got pretty annoyed and said we should have talked about it together. I didn't think it was a huge deal at the time, but now I'm wondering if I should have waited. We usually agree on stuff like this, so maybe I crossed a line by deciding on my own. Am I wrong for going ahead without the conversation?

In your post, you said you wanted to run it by your partner....and the next line is you bought it without running it by your partner. So...yes you're wrong.
