My sister had planned to get married in the summer of 2020, but since everything shut down and was canceled, she and her husband ended up getting married early… on her driveway, on my birthday.

My sister admittedly has been jealous of me since the day I was born. She was traumatized by my being here because she felt the shift of attention being fully on her to being mainly on me, the newborn, while she was a curious and energetic 2 years old. We never got along growing up. I always wanted to be her friend, but she always hated me.

Fast forward to when I turned 18, she was 20. We both broke up with our boyfriends and we decided to make a pact that we’d be best friends, all of a sudden. After 18 years of us battling, we were putting everything behind us, and starting fresh. Or so I thought. Until I found out she started a rumor about me that I had an incurable STD, which isn’t true.

Then when I met had another best friend and when I met my now ex-husband, she became very jealous of me spending time with them, and sabotaged those relationships and even at times completely withdrew from my life.

Fast forward to many years later while I’m going through my divorce, she decides to change her impromptu covid wedding ceremony on her driveway to a much earlier date which happens to be my birthday.

She said she chose this day because my grandparents on our dad’s side got married on this date (my birthday) so she wanted to have the same anniversary as my grandparents. We were not close to our grandparents, and we didn’t like our grandma at all. We did love our grandpa though. My grandpa also told me that I’m his favorite grandchild out of all his grandchildren, and he told me not to tell anyone else, but I told my sisters that.

I feel like she chose to get married on my birthday just to make the day less about me and more about her, like she wants more attention.

Do you think her choosing to get married on my birthday is an act of spite or AITAH for thinking that?
