AITA for excluding pregnant sister from my promotion celebration party?

Some people throw a promotion party like it is a victory lap. This one started like a family drama with a pregnancy subplot and a whole lot of old resentment.

A 31-year-old woman just landed a high-level job, so she invited close friends and family over for a small celebration at her house. Her 29-year-old sister, eight months pregnant, was not on the list, mostly because their relationship has always been competitive, with snide comments about OP’s success and constant downplaying. On party day, the sister called in tears, claiming she was being excluded because she is pregnant.

Now the family is split, and OP is stuck defending a “small and intimate” night that turned into a full-blown argument.

Original Post

I (31F) recently got promoted to a high-level position at work after years of hard work and dedication. To celebrate, I decided to throw a small party at my house with close friends and family.

My sister (29F), who is currently eight months pregnant, was not on the guest list. For background, my sister and I have always had a competitive relationship.

She has often downplayed my achievements and made snide remarks about my career success. Despite this, I've always tried to include her in important events in my life.

On the day of the party, my sister called me in tears, asking why she wasn't invited. She accused me of excluding her because of her pregnancy, which wasn't the case.

I explained that the party was small and intimate, and I wanted to keep it that way. She became even more emotional, stating that this was a significant moment for me and she should have been there to support me.

I stood my ground and told her that her pregnancy wasn't the reason for her exclusion, but rather our strained relationship and her lack of genuine support in the past. She hung up on me, and now our entire family is divided, with some siding with her and others supporting my decision.
