I completely respect that it's their choice to have any type of ceremony they want, but something feels weird to me that only women are invited. Should I care?

I guess I'm seeking ways other redditors would interpret hearing about this type of event, with the hope that it would help me figure out how I feel about it.


Clarification: The couple is my wife's friends originally, but we get along well enough I don't think twice about considering them my friends (and vice versa). So yeah, my wife is invited and I'm not.
