AITAH for not wanting my friend’s boyfriend at girls only events?

My (21f) friend (22f) brings her boyfriend to almost every girls event with our friend group.

For a little background: my boyfriend does not like her boyfriend and doesn’t want me around him for certain unrelated reasons. My friend and her boyfriend both know this. I don’t bring my boyfriend around their hangouts out of respect for that dynamic.

Despite that, she will still bring him to girl only events. Most of the time we clarify it’s “just the girls,” and she’ll still randomly bring him without notice. He’ll just show up or she’ll say last minute that he’s coming.

It completely changes the vibe. People don’t talk as freely, and it stops feeling like a girls night.

Now we’re planning a Galentine’s night, and she wants him to come. I feel like that defeats the whole purpose of it being a girls only thing. I don’t want to be rude or make her feel excluded, especially since he doesn’t have his own friend group, but I also feel like we should be able to have one night that’s just us girls.

I’m also not 100% sure how the rest of the group feels about him always being there because no one has directly said anything to me. But I do notice that the vibe shifts when he comes. Conversations feel more filtered, and he tends to insert himself into most discussions and make sexual jokes/comments.

I haven’t brought it up yet because I’m not sure how to say it without sounding mean. But I am getting fed up.
