Yes, she's coming as a plus-one with my brother in law. When I sent the invitation, I only addressed it to my brother in law. Apparently she didn't get the hint or my brother in law is stupidly bringing her for moral support. Because I can't figure out why she'd feel comfortable coming since it's been 6 years since she last spoke to us. And like I said, my daughter hardly knows her due to her intense years long grudge holding. We've always had a weird relationship with my brother in law and his family precisely for the reason that his wife is so toxic. Honestly, if it weren't for the papers saying we are related, we'd probably have nothing to do with any of them. They have never felt like family and the few times we've driven the 2 days to go see them, they have always had other people staying at their house who they showed more hospitality to than us. We were made to feel like invaders, quite honestly. I have always said that I wish we could trade them in for a different family!
