MIL has just come over to see us. For background, DH is one of three kids, he's the middle child and very much suffers from middle child syndrome. The sister is the golden child (eldest) and they do a lot for her. DH always goes on about it and a few years ago his aunt confirmed that he was not wanted and everyone has always noticed he's treated differently. It is quite obvious.
Anyway, over lunch I made a joke - she said how we shouldn't do something, and I said "but [DH sister] did it" and she flipped. She said she's had enough of me and thinks I'm a "cow" and that I give DH bullets and encourage him to feel less loved / hard done by.
He stayed quiet saying he didn't want the confrontation.
I am upset. This isn't true. I have my own reasons for disliking MiL (for example if I gain weight she will comment, thinks anyone above an 8 is fat and lazy etc, she's also very rude behind my back about my parents), but DH is the one who has always said to me he feels inadequate.
I don't know what to do. I feel so upset and angry.
No kids FWIW
