A co-worker (and close friend) of mine is invited to my wedding. I invited her and her husband, but not their 3 children. She told me today that her husband will probably stay home to work, and take care of kids. (Its a 6 hour drive for them).... I was ok with that.... not super close to her husband.
She offhandedly mentioned that her friend "Kate" has family near the wedding town and that maybe she will travel with and visit family. I said "Kate" is welcome to come to our wedding if her husband is unable to make it.
Is this ok? I mean, I invited her husband, but if he doesn't come, I have space and budget available for her to bring another guest. I honestly don't care who she brings... I just don't want to have made some awkward etiquette mistake.
