My bridal shower is coming up in a few months and since our wedding is on a short timeline I wanted to make it as cheap as possible for my bridesmaids as traditionally they split the cost amongst themselves. My personal preference was a more intimate event as well so the guest list I passed on to my Maid of Honor was just close friends and family. I made this decision after checking with friends who have recently been married as well as googling to see if that way okay as they old school tradition is inviting every single woman invited to the wedding. I was relieved to find out it seems to be completely normal to keep it to family and close friends nowadays. My MIL asked my fiance about the list 2 months ago and he let her know it was close friends and family only. He said she was disappointed but asked to add just 1 more person on. I agreed to ask my bridesmaids if this was still possible and it all worked out fine and I thought we were in the clear. She will have more family at my bridal shower than I will have of my own family as well as several friends. Just not any friends I have never met. My fiance also does not know the people that she wanted added so it’s not like they played a role in his upbringing and “deserve” to be there for any sentimental reason as it pertains to him. I just found out today that my MIL has been going around to all the bridesmaids messaging them the people she wants adding saying my fiance was confused and thought it was close friends and family only. They all told her to communicate any guests she would like to add with me. After learning this she would move into someone else. After telling my fiance this he admitted she has been calling him nonstop to fight him on the close friends and family thing but he didn’t tell me because he did not want to upset me. This means she wasn’t confused on what he said at all and that she purposely went around attempting to trick and manipulate my bridesmaids. AITA for this? I understand it’s not the traditional way but I’m really torn because I feel like it’s common enough nowadays and is that being what I want not enough? Who even WANTS to go to bridal showers? She doesn’t know I know anything. I think I will just add them even though I’m really stressed about adding several hundreds of dollars to the bridesmaids budget. My biggest concern is what does this mean in the long run if I reward this behavior. Or am I utterly wrong and selfish for being conflicted?
