<human>: I have been dating a girl now for 8 weeks and everything is going great.
One of my hobbies is Boxing, and I have been doing it for over 2 years now. I have a fight coming up soon, but my girlfriend barely shows any interest in it and has said she will not be going to it.. or any other of my fights. Her reasoning behind it is that she doesn't like violence or blood etc. I can understand this, as I know this kind of sport is not to everyones liking.
But I cant help but feel a little bit let down. I would love her to be there, and I have told her this. It is starting to get under my skin a bit and I don't like that she won't be there to support me.

I am just being selfish.. or do I have a right to be upset about this?
