I'm going to try to condense this as much as I can.
Prior to marrying my husband, him and his sister (let's call her kylie) went NC, despite living in the same house, sil still lives with the in-laws so we have seen each other every week for 5 years now. I have tried being friendly but she didn't want to know
(Can't blame her as she doesn't speak to her brother so why would she speak to me?)
After marriage etc same thing I got used to her being sort of invisible and we just wouldn't acknowledge each other
(I have tried saying hello etc when she comes in the kitchen but been ignored) so my mother in law told me to just leave her alone.
Anyways I now have a 2.5 year old. When my little one turned 18 months, my estranged sil randomly started talking to me when visiting the in-laws and asked if I wanted to start hanging out with her to get to know each other? So I thought great,
(She still don't speak to her brother (dh) ) she invited me to a party too which she and my dd started to create a bond.
Then my other sil (who I have always had a close relationship with) moved back to the area and out of nowhere Kylie stopped talking to me again with no explanation? She followed me on social media and I asked her and she ignored me? I asked her mother who just said "oh she's childish leave her alone" (I'm 27 and she's 28)
But she refuses to acknowledge dd when we come around, she tends to stay in her bedroom but if she comes down and dd says hello she will just say "hi" and walk off, so now I tell dd to come back etc because she looks visibly upset!
Fast forward last night, I receive a WhatsApp message that was clearly sent in error (purpose maybe?) from kylie with pictures of other sil kids quoting "my most beautiful nieces and favourites" she then said "oops sorry was meant to send to sis" and then on Instagram just posting pics of sils kids saying "my only nieces and nephews, my beautiful set. Etc etc" then after I view the story she deletes it?
I'm like wtf? I don't even know what's going on, dh said "there's a reason I don't talk to her, just block Her, dd doesn't need a auntie like that anywhere near her mother"
Am I being unreasonable to be a little confused and hurt at this?
