Person who I despise coming to my birthday party

Hey ladies, I need some advice.

My boyfriend and I have this thing where we plan a surprise party for each other every birthday. It just kinda happened that way and hasn't changed since 🤷

Anyways, my boyfriend and I are friends with two more couples- our co-workers, and their girlfriends. One co-worker has a very sweet girlfriend, I like her and enjoy spending time with that couple. However, my other coworker starting dating a girl (who also happens to work with us) and I despise her. Our personalities clash, and I feel she's immature and attention seeking and I have no respect towards attitude like that, not to mention I'm having a hard time with insecurity and my mental health.

Anyways, I made it clear to my boyfriend that I do not want her there. So naturally, our friend that's dating her asked why she wasn't invited to the group chat, and I got attacked for not liking her by our other friend. Keep in mind I didn't like her way before they got into a relationship... Anyways, now everyone wants her to come to MY birthday party because it's at a club and it would be weird to let her boyfriend go alone, but I don't understand why I should have to invite someone I don't like so my friend can have his girlfriend there... I feel like everytime we're all out together, everything is about her and I hate that. And of course my birthday party has once again become about her.

Any advice?
