Lately I've been antisocial

And it is causing some issues in my marriage. I'm 23 weeks and My husband is hosting a Super Bowl Party and I'm not feeling it. Initially, I told him I was okay with it as long as it's just his guy friends and no spouses. I really don't want to entertain anyone. I want to just watch the game in the bedroom and let him do his guy stuff. But now a few wives are coming and I'm livid. Has anyone else felt like this?
