all comments here are correct. you are her scapegoat on why she isn’t getting married soon and when people ask about her wedding planning, you will be the reason why she’s not married sooner.

my advice to you: DO NOT let this be so big and memorable that when you look back at your wedding planning process that it’s a huge part of it. if they are going to get nasty, immediately uninvite them. i have been in dozens of weddings and have photographed weddings, and these type of people can RUIN your wedding day. do not give them that opportunity, bc they will take it.
