One of my sisters and I have no relationship and we decided to stop talking to each other because the relationship was toxic. None the less, she got married nearly a few years ago and everyone in my family but me was invited to both the wedding and the anniversary party. It really breaks my heart too along with feeling angry with her.
If that's not enough, she has me blocked on social media so I can't contact her and even when I wished her congrats after hearing that she and my brother-in-law finally tied the knot.
I am sorry but I am both very sad and angry with her.
