My fiancé's family is wonderful and I wouldn't hurt them for the world. I'm a bit stumped on this one though--they keep inviting people or telling them about our wedding and acting like a verbal invite is all that is necessary, without consulting us first. We are paying for it, and I don't mind the extra company necessarily, but I do want a firm headcount. I need it for rentals, and my caterer will need it too. I don't know how to control my guest list when I don't even have all the names or addresses of everyone they've asked. How do I get this to stop snowballing?
