My DH has 2 brothers and one sister who all have partners/babies/young children.
I'm in process of arranging an afternoon tea for the girls which will include my mum in law.
One of our sister in laws (call her Sadie) is very, very, very hard work. Walk on eggshell types and she becomes annoyed if you say something she doesn't agree with.
Sadie has been rude to mum in law in the past to the point of tears. She's from another country so has no family or barely any friends here. My mum in law encourages my friendship with Sadie, which is fine but everytime I see her I'm on edge.
My sis in law (DH sister) dislikes her for various reasons. I can understand why she doesn't like Sadie and I know Sadie is really hard work.
Also Sadie doesn't like my sis in law and is resentful of my mum in law. Sadie told me this and I've never repeated it to anyone.
I've just told my sis in law that I have asked Sadie to come for afternoon tea and she isn't happy about it. My sis in law (call her Katie) has two babies (newborn and 18 months) so doesn't ever get a break.
Katie has told me that she doesn't want to spend a rare day off on edge and anxious. But if I hadn't had invited her then Sadie would be upset and my mum in law wouldn't be pleased.
What do I do? Feel like just cancelling whole thing. I can't be bothered going out where people don't like each other and I have to spend the day placating everyone. But I love my family so I'm stuck.
