So in general I am being very inclusive with regard to all SOs when it comes to all aspects of my wedding and pre-wedding events, as etiquette requires, but I do have one question. One of my BMs is gay and in a relationship with a girl, and I'm just wondering if it's acceptable to not include her in certain "girls only" events that other SOs won't be invited to because duh, they are guys. I'm talking specifically like bachelorette party (which will just be me and my BMs, not sure if other female friends outside of the bridal party are traditionally invited to these types of events but we're not going that route... oh and to be clear I'm not planning my own bachelorette, one of my other BMs who has offered to throw me one came to me asking about if she needs to include BM's GF) and morning-of-wedding pampering (also just bridal party plus moms). She IS traveling to be at my wedding, so there's that. I would love to have those times for just me and the gals in my bridal party (which is small and very close-knit), but I also don't want to be rude. And then there's the issue of what's fair to other SOs- this is probably immature of me but I know from past experience hanging out with my BM and her GF for "girl time" that I personally get bummed being around another couple without my FI- all of a sudden I just start noticing every little gesture and get all like, awwww I want to hold hands right now etc. So what do you ladies think, do invitations need to be extended in these scenarios?
