So my SIL is batshit. I mean properly mad and obsessed with hers and DH's DDad (actually it's their Step DDad but is a wonderful father and grandfather).
She regular throws a strop if she isn't seated next to him at family meals/gatherings.
Counts how many words he speaks to me or DH and compares them to how much he's spoken to her then will sit in silence for an hour before blowing up about it.
Could spend 6 out of 7 evenings in the week with MIL and FIL but all hell breaks loose in we spend an evening with them without her.
Point blank refuses to see that she is doing anything wrong.
It's now got to the point that we joke she must fancy FIL (but actually we aren't joking and it's incredibly worrying).
She's even jealous of her own daughter (18) getting any attention.
She's a 40 year old woman with 3 children. It's weird and honestly I'm just over it. Having to watch where I sit incase she has a funny turn.
We have sons the same age and she can't stand it.
She can be the nicest person even and then sometimes just loses it over these silly things. Their biological father left when they were very young and and DH has always been closer fo MIL than SIL has (although SIL would happily admit she's had more given to her both practically and financially than DH has).
I don't know if it's an abandonment issue or something but it's ridiculous now.
So please just make me feel like I'm not going mad and other people have families like this?!
