Please help! I have a very intrusive and difficult mother in law to be. My best friends are in the process of planning my surprise hen do, I have given them a guest list of which included my mother in law to be. I did not invite my brother in law to be’s new girlfriend, we are not close or friendly and she has been rude to me on an occasion before. My mother in law to be is pestering my best friends into inviting the new girlfriend to my hen do. (This isn’t the first interference or argument she’s caused recently). If I don’t invite her I will upset an already interfering and difficult mother in law to be, but I feel torn because I am not close with this girl but I don’t want to cause a family rift. Am I selfish for not inviting the new girlfriend or should I stand my ground?
