My sister got married a year ago. Her husband has a daughter who is 8 years old. I actually never met her or my new BIL. My sister and I live states away and we’re not close, neither is she and the rest of our siblings. We talk a few times a year over the phone but we’ve never made it a priority to hang out. My son turned 9 recently and for his birthday, my husband and I took him and his three best friends to a water park and we stayed in a nearby Airbnb. Of course we had to confirm with the parents of the other kids and all that. But we thought it would be nice for our son since he wanted to do a water park. The kids all had a great time.

My sister heard about the party through our mom and she asked why her stepdaughter had not been invited. She told me it would have made more sense for her as my son’s cousin to be taken on a weekend trip than simple friends. She said her stepdaughter never gets invited to any of the kids birthday parties (I only have one, other siblings have kids though). I told her this was about who my son wanted there and he’s never met her stepdaughter. I don’t even think he’d remember my sister honestly. She told me nobody will get to meet her if we don’t make the effort to include her. I told my sister it’s difficult to meet someone who lives on the other side of the country and a weekend away together with strangers would not have been a good way for her to be introduced to us.

My sister said I was still an asshole for not inviting her stepdaughter.

AITA?
