My girlfriend (36F) wants to break up cause I (39M) bought the wrong chocolate

So yesterday my girlfriend asked me to pick up some chocolate on my way home. She specified that she wanted white chocolate and the specific brand “Milka”. I went and got Milka chocolate but they didn’t have a white one so I got a pink/strawberry flavored and a blue one (some kind of citrus flavor?). I left one at her doorstep and the other at mine (we don’t live together).<br><br>About an hour later she’s texting me, livid that I didn’t get white. She said it was a pretty straightforward request. I said I know but there wasn’t any white and I at least wanted to bring something. She kept going on and on about how I “failed the test” and that she’s done with me.<br><br>I tried saying maybe it’s not that big of a deal to get so upset but that only made her worse. I said we could still go and get the kind she wanted but again, I got yelled at. This went on for a few back and forths on the messenger. <br><br>I said I wasn’t going to just sit there and be yelled at so I suggested talking over the phone. I called her and she answered, still angry. I said “Listen-“ but before I could finish she interrupted and said “Listen! You failed the test! And I think we should break up” I laughed and said what? <br><br>She was serious and just kept going on about how I couldn’t even get a simple thing right; that I just disregarded what she said and went and got random flavors, that when she tells me something she means it, and all kinds on nonsense. <br><br>I was dumbfounded and at a loss for words. I asked her to calm down and take a moment but she just said she’s done, not gonna waste her time and “maybe we can be friends someday” and just kind of ended the conversation.<br><br>I just let it go and figured she was distraught so best to give her space. I texted her today and said I didn’t think a breakup was warranted but she didn’t reply. I told her I was going to come see her (I’m going to an out of town wedding this weekend) and she just said ok.<br><br>I’m at a loss for what to do. I could understand being upset if I completely disregarded a request but I also thought I was being thoughtful to bring something in general? I don’t understand where “failing the test” comes into play. I can’t just let the relationship end like this.<br><br>Edit: For everyone saying “Maybe she wanted it for a specific reason”. Yeah, I’m sure she did. She just wanted chocolate. <br><br>Edit2: We’ve been together for about 8 months. On one occasion she told me she wanted to go to a specific restaurant but I couldn’t get a reservation at. She got angry and said “make it work”. The next day I got a very very very long text about how I don’t listen and I need to make things work/figure it out. I tried to say “well maybe they’re busy” or “I can only try so much” but that didn’t help. She also called me dense in that message. Also on another occasion I picked up a snack she wanted except it was whole wheat and not white and she got upset and said I misheard her/ignored her. And lastly, when we were still getting to know each other we were at a cafe and I offered to buy her one of those little pastries and I asked what flavor she would like. She said strawberry “or whatever, it doesn’t matter”. When I got strawberry she said “I knew you’d get that, because you never listen”. I was kind of like “uhh?” And she said it’s fine and thanked me. <br><br>Edit3: Update: I went to her place. She was calm and had a little smile on her face. I asked what’s up and she just said “I’m not gonna settle for boys anymore. I need a man. I think we’re done” I asked what exactly she means by that and she basically just repeated herself. I asked if she could give me examples and she said the chocolate incident; she said I didn’t get a white one because I am “afraid” of going into stores and asking people about things so I just grabbed random ones and left it and went away with no regard for her at all. She also repeated the no reservation thing and the white bread thing. I tried to say I don’t think that makes me a little boy but I think she had already made up her mind. I was gonna try to work on things but something tells me not to bother.
