Just need a moment to vent...ahh! My BIL has a new girlfriend. She’s perfectly polite and we’ve met her a few times. No issues with her (she’s also American, like me). My BIL asked his mother (my MIL) if the new girlfriend could come for Christmas because said new girlfriend cannot afford the flights to the US to see her family. Therefore, she’s on her own.
My MIL has a complete meltdown. In front of everyone.
My MIL begins with calling the new girlfriend “a complete stranger” and says she doesn’t want her in her house at Christmas. She also says that because they met on the internet she
really doesn’t want her in the house.

Everyone is horrified, and she says how having the new girlfriend for Christmas is one more mouth to feed, so therefore more costly. My BIL offers to give her some money for the Christmas meal, but she declines because the new girlfriend “is from the internet.” She proceeds to say how “pleased” she is that I will be in the US for Christmas, but “most annoyed” that my husband chose to spend Christmas with his side of the family this year as she now has to get him a gift and also feed him (my husband only did this because he started a new job and couldn’t get the time off over Christmas).
Thanks for your time, everyone. It’s been a bizarre (and cringing) day.
