My sister is toxic. She is a first class narcissist and despite being 3 years younger has made my life hell for years.
She has spent years telling me off for how I parent my dd, we have very different styles. I have strict boundaries and expectations of behaviour where dd is concerned, she knows these and we very rarely have any issues other than the usual cheek or inappropriate sarcasm. My sister chooses a far more laid back approach, her way of dealing with poor behaviour is to delay with it in a "that behaviour makes mummy sad" way. Each to their own. She has her way and i have mine.
She constantly used to belittle me and undermine me where dd was concerned. It came to a head in 2019 and I had a go at her about it. Told her it was unacceptable to undermine me and whether she agreed with my rules or not is irrelevant. She can talk to me privately but she doesn't get to tell my dd to ignore my instructions because "mummy is being mean".
She basically told me I was a shit parent and she had every right to "protect" my dd.
I told her she could either keep her opinions to herself or stay out of my life. I have made no contact since. Every so often she will pull emotional blackmail out the bag and send messages about her kids missing my dd. Normally I ignore it but Xmas 2022 I pushed back and told her to keep her blackmail to herself. It went down like the proverbial fecal sandwich.
Dd sees her during school holidays, my parents take her to my sisters or she goes to them when my sister comes to my parents. I have never stopped them having a relationship with dd and I wouldn't. She will make her own choice when she is older. She adores her cousins so I am happy for my parents to facilitate the relationship. So her claim that they never see her is absolute BS.
I got engaged earlier this year and the wedding is booked for summer 2024. My parents are demanding I invite my sister and her family.
I don't want them there. I have no relationship with her or her family and honestly I don't want one.
There is a huge back story that includes being forced to have my BIL as dd's godfather because my sister kicked off, but when I mentioned that my then partner would drop me off at a family party she threw a hissy fit about it being her party and I was out of line demanding someone else was invited. I never even mentioned him coming, I just mentioned that we would be staying at a hotel locally and he would be dropping g me and dd off at the party. She assumed the rest and through a wobbly.
My mum is adamant I have to set things right because I am the eldest and my wedding needs to be some sort of family reunification.
I don't want the stress or agro.
Help me with advice on how to tackle this with mum because there is no way I am.inviting my sister but I don't want it to wind up as a row with mum!!
