It appears that a bunch of people are assuming that they can bring a plus one to our wedding and some of these people are not dating anyone. We are definitely inviting couples that have been together for awhile. I just do not know what the cut off is. For example I had lunch with a friend a month ago and she said I have been single for so long, but I have to figure out who I can bring as a date to your wedding. I should have nipped it in the bud right there, but I just blew it off. Fast forward to today and I see she is dating a guy now..so they will have been together for 3 months by time my wedding comes. Do I have to invite him now?
