My sil has always been horrible. We couldn't understand her behaviour at first but she used to accuse my family of not making an effort with her and treating her badly, when we hadn't.
We tried to make amends. She's quite materialistic so we bought her nice gifts for her birthday and other occasions. I'd email and text her and see how she was. She would reply but never initiate any conversation. We would always try to make her feel included but she always had some sore point. My brother gave up trying to ask her to stop being rude to us as it it just made her worse.
She's polite enough when my brother was around, but often when he was out of earshot, she'd make some horrible PA comment.
My mum is often sad about how things are with her and feels cut off from my brother and her grandchildren. Sil has no sense of humour at all and is quite limited in what she talks about (we've always tried to include the topics she feels she can talk about). She also lies quite blatantly about things we've apparently said.
I now cannot stand her and make no effort with her whatsoever. Its a horrible situation for my brother. He's not one to open up so I don't know what their relationship is like but I know this situation isn't easy for him.
I don't really know what I'm asking as I know everyone is different and even with narcissism, there must be degrees of it?
I guess I just want to know if it does sound like she's a narcissist and how we can deal with her. A friend who knows about the situation said 'I bet you can't wait for her to get some comeuppance' but I don't want that.
I'd just love to be able to maintain a decent, polite relationship with her but that means she has to change which I doubt will ever happen!
So whats the next best thing?
