Sister in law cold shoulder

[Bruce123]

my sister in law completely cold shouldered me at a family Christmas do. (Avoided eye contact, moved to a different room when I entered, and refused to talk to me, got her two adult daughters to change the seating plan 3 times). All of this because I refused to apologise to her when tried to enforce a boundaries around her telling me how to parent my adult kids. Apparently I was a “terrible mother” not to support my daughter in getting a boob job- my daughter thanks me for it now btw. And for not telling my 20 year old that drugs were a bad idea- (like I hadn’t enforced that message already since she was about 6 years old!).

I’m unsure what the AIBU? You obviously have different parenting styles. Do you need to see her often and socialise with her? If not, just mention to your partner/husband what’s happened and excuse yourself from those social engagements. If you still want to attend the same social event, just avoid her. It sounds a little school playground to me (but I’m not close to my SIL- we have little in common but can chat superficially for an evening do!

so probably not the best advice! )

It sounds like the two of you have fallen out. So it doesn’t seem particularly weird that she would avoid you.
