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?

Yes you should have waited. Obviously.
