My(24M) girlfriend(24F) wants to break up cause I got a little too happy that the patriots won the super bowl

I don't even regularly watch football, but for some reason I was hyped for the super bowl this year. I invited her over and we watched it, the food I made was great, and the company was good too. We had a great time. And when the patriots won, I did a little happy dance and screamed in excitement. My girlfriend saw this, and she saw me being a little too excited and happy and was turned off, because apparently she thought it was too weird that I was being that happy. She leaves, and then she breaks up with me through text message, saying that she can't be with someone that gets *that* happy over football. She even went as far to say that I'm a little bit demented? I was taken aback by that, but I mean I was pretty happy. I thought that was pretty normally? What do you think, Chambers? Was she justified in breaking up with me over this?<br><br>TL;DR: I got too happy that the patriots won, and my girlfriend saw it and broke up with me over it
