My sil is a complete narcissist who takes no responsibility or accountability for her behaviour. She’s constantly looking to be offended and play the victim and she extends this victim hood onto the kids. I have 2 other SILs(there’s 4 bros) one lives out the country. Me and my 2 sil used to hang around with each other when kids were young out of being pleasant and the kids were all close. Over the years her behaviour has been Terrible and she is total hard work. It came to a head 3 years ago and she accused the family of causing her sons mh problems as they felt ignored and said we’d be responsible if he took his own life etc, really crazy stuff. We all including in laws cut her off. I’m that time I have became best friends with my other sil and our kids get on, it’s just east and nice. In the past month th narcissist sil has started speaking to in laws and they have asked us to all forgive and forgery. I have stated that I am happy to move on as a family and be in her company at family event’s however I’m no longer wanting to be friends as it’s so negative and she has no boundaries. My partner understands this. My nice sil has been answering texts from her and it’s clear to see she’s not changed, still wanting to play victim and still wanting to bitch about family members. So this past week her husband had been texting family chats(we all know it’s her) and my partner complaining that his kids are continuing to be hurt etc as my child was out with her cousin and I was seen out a walk with my nice sil. Basically she’s not happy with just getting together for family events and wants things to be how they were and feels it’s unfair for me and my nice sil to meet up with kids and hers aren’t invited( even though we all like the kids, it’s her we don’t like). My mil is now pissed off saying we are not nice to leave her out and all the wives are causing her precious sons problems. I can see how it’s not nice but 3 years have passed and my life is so much better without her(she makes me anxious) and I don’t think I should’ve be allowed to meet up with my other sil. I’m 44 and our kids are all adults! I know it may seem like an obvious answer but my partners brother, mother and sil are making out Luke I’m continuing bad feelings and being mean!
