So honestly, I really need to vent and see what you ladies think we should do/how I can make peace with this.
My 31-year-old fiance has four uncles on his mom's side. They all ran the family business started by his grandpa up until last year—when the youngest brother and president of the company (we'll call him X) finally, after years of terrible business practices, ran it into the ground and sold it.
This involves us because my fiance was working there at the time. His uncle X constantly demeaned him, withholding simple information so my fiance would look stupid in front of customers, and generally had a nasty, condescending attitude toward him. On top of all this, my fiance was renting a space for his business in their factory. Once his mom confided the business was going to sell, my fiance asked uncle X to let him know how much time he'd have to move his business out. Uncle X never responded, going behind my fiance's back to almost get him kicked out with nowhere to go (we found a place to rent last-minute).
Okay. This is all background. Ultimately, it boils down to the condescension, the conniving attitude, and now, the financial ruin of his other brothers, sister and 92-year-old mother. He's a terrible, terrible person for so many reasons. End of story.
Now that we're actively planning our wedding, we had to address the fact that we aren't inviting uncle X. His mom became quietly enraged (scary, actually) and immediately said she "wouldn't be able to come then," though she later conceded she'd have to think about it.
I'm so livid and hurt (mostly for my fiance) this his mother could say this to his face. That she's choosing her awful brother over her own son, who did nothing to deserve the treatment he got (and she knows it). Honestly, it's verging on creepy... almost like Stockholm syndrome. I'm afraid to know the reasons why she's so unfailing devoted to her brother, who treats her like a child and has her coming home from work crying. But that's another facet to this story.
Ultimately, we're standing firm on our decision, but I have so much anxiety, and not just for my wedding. If she does decline to come, my fiance says he's permanently ending his relationship with her (and who could blame him?). His dad and sisters (as well as my family) totally support our decision, and won't forgive her if she sides with her brother over her son. As you can see, the repercussions of this debacle will be much longer lived than just our wedding day.
I'm sorry this is just a big rant. I know what we HAVE to do, but I don't know how to process the possibility of losing his mom forever.
