So my fiance and I's best friend is officiating our wedding and we have 78 days until the wedding. We saw him a couple weekends ago and asked if he could bring his girlfriend (who we have never met). Of course I was caught off guard, but I said that we would talk about it. My fiance's argument is that he is our officiant and they have been dating for a year and a half (they are not living together). My argument is the fact that we have never met her and by the time we do, the wedding will be in a few weeks and we would have already booked chairs and tables. What are your thoughts? No one else is getting a plus one so that's where I'm torn, because that's not fair to anyone else.
