I actually don’t feel comfortable attending friend group’s game night any longer after female friend revealed her love for my (28F) bf (32m) plus I’m feeling very conflicted

This girl messaged your pet the other night point blank saying that she loves my partner in a non platonic method. Bf and I share a phone so I saw the message pop up and tell him what I saw. He seemed kind of surprised but not troubled by it like I was. He said it' s regular for people to develop crushes when spending time and having fun with each other, which sure, I accept, but love? It makes me feel uncomfortable, and I said I didn' t wish to go to next game evening because I feel like limitations have been crossed. I feel such as I' m going insane because I' m the only one who finds this actually weird and uncomfortable. Once i told my bf I' m not going to go, and that I' m not going to power any decision on your pet, he opted for canceling video game night instead (we get it at our house).

Personally i think like this is a bit of a police officer out for dealing dealing it and setting boundaries with this particular person, and makes me personally feel like a dick. I actually said I cod place my feelings aside which j don' t wish to ruin things for others, yet he insisted he doesn' t want me to have to do that. Now he changed his mind and wants to go ahead with it but We definitely don' t feel like going if she' h going to be there and nothing has been resolved.

I' m confused and just really need some outside opinions. Thanks.
