Is it appropriate to game for 3 hours when your partner is over?

I'm over at my boyfriend's right now and noticeably upset because he asked if he could game for a "little bit" which turned into damn near 3 hours. I'm giving him the cold shoulder because I'm afraid of saying something out of line. I feel like that's too long to play when I'm over but not sure if this is normal and if I should just deal with it.

Mind you, I don't care about gaming and he knows that. So playing WITH him is not an option.
