Namechanged for this. Apologies for a long one.
I’m gonna start by saying that our relationship with DS has always been complicated. I have two sisters that are close in age and I am 9 and 10 years younger than them. I’ve always gotten very well with my eldest sister, never had any issues despite the age gap, she’s been always friendly and supportive of me. Middle sister (DSis for this thread) on the other hand has always been on and off with me. As an armchair psychologist I would say maybe she resented me being born and “stealing” her youngest child status? But who knows.
As a child I remember she never really liked me. Was always strict with me, yelling at me to clean up my toys, she hated most of my friends, I remember she once kicked my friend out of our house when we were about 5 who came for a playdate. As I was a teenager at secondary school and uni she resented my parents giving me money (even though they supported her through school too) and only ever started somewhat accepting me once I started working, built a successful career and became independent. Our relationship improved then but still goes through waves of issues and periods of us not talking (initiated by her for any random reason).
My parents never took anyone’s side, just left us to it, partially because whenever she would get mad at them for any “injustice”, she would easily not talk to them for 6 months (so they never want to rock the boat with her). One highlight of her not talking to them included her not inviting them to her graduation. Another one when we went for a family ski trip for 5 days, she got in a mood at the end of it for no reason (literally no reason that we could understand, she just wasn’t in a good mood that day) and stopped talking to any of us for something like 4 months. Nowadays she’s mostly fine with my parents (well my dad died recently so fine with my mum) and us and it’s her DP who’s on the receiving end of her silent treatment usually.
I live abroad with my family (pregnant with DC #2 now) and visit my hometown once or twice a year for extended period to get together with everyone. She’s gone quiet on me in our WhatsApp recently because I think she was mad I planned the visit for when she was away with her family and so we only overlap for 3 days. After she blanked me on WhatsApp a few times, I stopped sending her pictures that I normally send to my mum and other sister too. This apparently made her more mad (I assume, she never tells what’s wrong). Anyway here I am, hoping to celebrate my daughter’s birthday and to enjoy the last few days of my stay with family here (I won’t come for another year at least due to pregnancy and then having a newborn) and she got here. Completely ignoring me, blanking me, chatting cheerfully to everyone else (including my DD and DH), making me feel completely awkward to even be here.
AIBU to feel like what the actual fuck? Is this in any way normal for anyone over the age of 15? What do I do? I’m sick of always approaching first, apologizing when I haven’t done anything wrong (I was sick in my first trimester so couldn’t come at different days and she knows), and I’m pissed off that she ruined my last few days of the visit.
She’s not like this to my other sister who often excludes her from their invitations etc. (and she probably would be like that to my mum but my mum knows to thread carefully around her)
