SIL and I don't have a particularly warm relationship. Over the years she has made me feel unwelcome when we visit the in-laws, has said a number of inappropriate things and at every opportunity will try her hardest to get a cheap dig in - if not about me, then my family.
I've had no contact with SIL since Christmas when I told DH that I was going no contact as I was fed up of her comments. He got it as she was also inappropriate to him, but given that she is his sister he won't go no contact.
I've always had the impression that feels that I have taken her brother away from her - she seems to think she knows him pretty well by commenting previously and inappropriately on her perceived perception of our married life and his evident bedroom frustrations. She oversteps the mark, crosses boundaries I have put in place and basically any opportunity will say something to belittle me or have a dig.
We have a family WhatsApp chat - I get on with the rest of DHs family, but I have muted the group as I can't really leave the group.
Yesterday DH posted a jokey thing up about a husband and wife. SIL is straight on it and in caps is writing LOVE IT LITTLE BRO and then fills the rest of the message with hearts, kisses and other emojis. She then has evidently misconstrued the joke and thinks it is a dig at me and then (I won't say what the joke was as it will be outing), and then posts a close up photo of just her and DH with a strength arm emoji with lots more kisses and hearts.
I think she's batshi* anyway, but feel like she is now having a dig at me by positing comments and photos of just her and DH and telling DH not to forget his roots and who is BLOOD family are - for context we live a good 5 hours away.
DH thinks I am overreacting - I probably am, but AIBU to think this woman is just as mad as a box of frogs? I dread having to spend any time with her as feel she doesn't make it easy for me - last time we visited she screamed at me in her own home, throwing open doors and asking if I wanted to see inside her cupboards etc.
