My girlfriend is breaking up with me because of this game

Yesterday I sent her a reel of a girl saying what it was like to have a mastectomy surgery and I wrote "the mountains of montaklar are gone". She didn't understand and asked me to explain, I explained the context and she wrote "ah, it's that game you've been playing", I said yes and that she should try it too because it's really good. She then started arguing with me saying that I should "like more normal things". At the end of the discussion she simply stopped responding to me for a few hours and two hours ago I woke up with a message from her saying he never wants to see me again and also blocking me.

I still don't know how to react to this, but I found a funny story to share here.
