Okay, so one of my fiance's groomsmen has a girlfriend whom I absolutely detest. Please just believe me when I say that she has been nothing but terrible to me.
When we asked this groomsman to be in the wedding, we told him up front that his girlfriend was not invited; he is more than welcome to bring a guest, so long as it isn't her. He was totally okay with this (he understands why we don't want her there)... but at the time, their relationship was on the rocks (they're a on-again off-again couple). Well, it's now two months before the wedding and they are very much together.
Do I need to invite her? I really don't want to, and because we told him she wasn't invited up front, I don't feel like I should now have to invite her. However, I feel bad, because if I don't allow him to bring her, he's going to be dateless.
Opinions?
