Backstory - my sister has various mental Heath issues, manic depressive and anxiety.
We hadn't spoken since we were teenagers apart from at big family events where we were always civil.
She is so the most negative and judgemental person I have ever come across. She acts like we are in competition so anything I do in my life that I'm proud of she instantly knocks down or finds fault in, it's exhausting.
Every time I tried to confront her I was apparently being insensitive to her MH problems (this coming from our mother).
E.g When we were at school and I achieved reliably good A level results and came home to be told not to 'rub it in her face'.
She has always had a terrible relationship with our Dad and Step mother (step mother has her own set of MH issue by more OCD related that depression).
When we were teenagers I lived with Dad and half siblings, whilst she stayed with Mum. I couldn't bear to be around her at that point.
Roll forwards now both on our 30s and I had my first DC last year.
She reached out an olive branch wanting to be an auntie and I welcomed her.
Every time my mum comes to see us she comes too (she can't drive or get public transport alone because of the anxiety)
At first (with a lot of tongue biting on my part) all was well, we were getting on, she is great with the baby. Happy families.
The last couple of times I have seen her she has just started to wind me up again.
Unsolicited parenting advice (she has no children, but because all her friends have she seems to know an awful lot about it)
She told me I was selfish for not wanting to move to a cheaper area so that I didn't have to go back to work etc etc just little digs nothing major.
Also it's really starting to get to me that I havent actually seen my mum alone since I've had the baby. Sister is always there. They come over or we meet up about once a week.
Me and mum never had the best relationship anyway because of the time I spent away from her since being a teenager but still would be nice for my DC to spend time with grandmother.
The real thing that gets to me most though is the way she lays into my Dad.
They clearly have a bad relationship but I have a great one with him and his family. (Step mother and 2 half siblings) we meet up for family meals often and is always fun and everyone gets on.
My sister now has decided that because we meet up without her she is being ostracised and throws a massive hissy fit (via Facebook) the past couple of times we have all met up.
The problem is when she is there the atmosphere is awful and she makes everyone uncomfortable.
It's got to the point where I don't want to meet up with my family for fear she will find out again. I never outright tell her but my mum always asks if I've seen dad (annoyingly in front of sister) and I can't lie.
I guess I know I am BU because she is a family member and it's not her fault she has MH problems and I know they are ultimately the route of her behaviour but I just don't want to spend time with her but I don't want her to feel pushed out either.
Also to add I can't stand her conversation. She has zero culture and has hardly ever left the town we grew up in. We have nothing in common and she just talks and talks about the most mundane stuff at me and I just sit there and listen wondering what else I could be doing with my afternoons whenever I see her.
The question is.. AIBU to ask my mum to come alone without her and to try and phase out the amount of time to have to spend with her?
