My girlfriend broke up with me because of Umineko

I don't even know where to start. Me (25 F) and my (ex???) girlfriend (24 F) have been dating for a few months. We were going to move into a house together, not because of our relationship but for financial reasons, as we are both young and this saves us several hundred pounds worth of rent. I thought things have been going GREAT. We share several interests, worldviews, and friends, although we do come from very different backgrounds. Well, yesterday we were chilling out in our living room, cuddling and reading Umineko, and eating some frozen pizza that we had made together. For whatever reason, I kept on wondering the significance between one of the new characters that was introduced in Chapter 7. Well, I happened to come up with a weird theory after learning about Kinzo's past, and out of nowhere she throws my arm off of her and says "I can't handle being with some ♥♥♥♥♥♥♥ idiot who can't even solve a kids mystery game after having spent 60 hours on it." I laughed it off, thinking it was some kind of joke, but then she stormed off to her room and slammed the door. She hasn't answered any of my knocks, texts, or calls. Some of our mutual friends aren't really responding to me, while others are alluding to me not even being anything like Beatrice. Last night she took my Beatrice fumo into her room, as it was nowhere to be seen in the shared space. I'm so ♥♥♥♥♥♥♥ worried and I feel like a ♥♥♥♥♥♥♥ loser. Thanks for listening.
