Baby shower

I’m having my baby shower this coming Sunday, I’m taking all the precautions, having less people than the full compacity, checking temps all of that. Well one of my best friends lives like an hour and a half away and wants to bring her boyfriend. I told her that if he wants to do something else for the two hours like golf or fish because it will be in the golf course clubhouse he could because he would be the only guy there. My husband isn’t even going. Every baby shower I have been to has been all girls, and the boys throw the diaper party. She’s going off about how it’s so shitty that my husband won’t be there because it’s his kid. I’m trying to stay calm and not go off but I’m losing my patience. Any tips on how to stay nice and not be a bitch? Lol
