I am divorced. One of my closest friend's dgt was getting married and I was invited with a guest. I decided to bring my adult son as my escort. When I casually mentioned this to my friend, she informed me that he was not allowed to come as they were not inviting "children of friends" to the wedding. I replied that he was coming as my escort, not as a friend's child. She told me he could come "for dessert," but not for any other part of the wedding. I decided to attend the ceremony only, and not the reception. As an aside, I was one of the hostesses for the bridal shower, which I proceeded with after my conversation with my friend. I was ambivalent about this, given the tone of our talk, but wanted to focus on her dgt, and not our disagreement. Several days before the wedding, my son experienced an acute mental health emergency and was hospitalized. Due to this stress, I needed to go to the emergency room, on the day of the wedding, with severe high blood pressure, and was instructed to be on bedrest for 2-3 days. I sent a message with a friend that I wouldn't be attending the ceremony. My friend has not spoken to me since, and will not respond to any of my messages. She had told others that our friendship is over, permanently. I am heartbroken, as we had been friends for over 20 yrs. I cannot tell her, or anyone else about my son's illness (was diagnosed as bipolar), as I wish to respect his confidentiality.
I would like some feedback as to the proper etiquette when one is invited with a guest. Could I have done something differently?
