So, among other issues is this one.
My mom and sister can not stand each other. Full-out disowned, will never speak again level. My sister and I are close - she's my MOH. My mother and I have a strained but intact relationship. I am Switzerland. I am not happy about it but that's how it has been and will remain.
We're having a small wedding, and my only bridesmaid is my maternal grandmother. So my wedding party = my sister and grandmother.
My mom and grandmother live next door to each other and see each other very regularly, nearly daily.
I'm stressed about having my mom and sister in the same building for my wedding, but with 60 guests and the knowledge that it's my wedding day, they have both agreed to just avoid each other.
Now, it's time to plan the rehearsal dinner. I've never really known what all goes into that, and now that I'm looking it up, I'm supposed to have the officiant and his spouse, the attendants, and our "close family." (And out of towners, but we have none.)
Well, close family clearly involves my mother, though she has no formal role in the wedding. I just realized that this means putting my mother and sister together in a group of only maybe 10-15 people, and that could be a freaking catastrophe.
I can't not invite my mother. She's my mother, and she lives next door to my grandmother, who's in the wedding party.
I can't not invite my sister. She's my MOH.
What do I do? Any advice is appreciated.
