We are paying for our whole wedding ourselves so the budget is limited. We've told all of our friends, bridesmaids & all, that they can't bring dates unless they are in a committed love relationship (not married, but committed). We've gotten lots of push back, but have explained that we can't afford it. There's been some grumbling. Now, my fiance is allowing 1 friend to bring his EX-girlfriend who he just broke up with 2 weeks ago. (drama anyone?) And, he is letting a friend bring a random date because her ex-boyfriend is going to be at our wedding with his actual girlfriend of 8 months. They've been broken up for almost 2 years! She's going to know 20 people at our wedding, why should she get to bring a date? We can sit her with her best friends. I don't get it. We don't even have a name of this mystery date. My fiance won't let it go. What is the right thing to do?
