So I (F 26) was talking to my dad on the phone. For context, he remarried when I was in my early 20s to someone who was really an extramarital partner. Anyways I've let that go but have had issues with her overall entitled nature (along with that said nature in her children as well). My dad seems to see it mostly only in my technical older stepsister. He talked to me about how he spoke with his wife about issues (basically stood up for me and my brother). We also talked about the older stepsister and I having a recent message exchange about Thanksgiving, where we were cordial with each other. He said it's good I don't get too close but also am cordial. I've come to accept he's a "keep the peace" type

Anyways when he mentions something about them still being family. I immediately said they aren't. He said something like don't stoop to their level and antagonize, what about when us kids have weddings and such occasions-it won't look nice, etc. I immediately said people do when they're old enough (as I am and have been the only financially independent one thus far too). Am I right about that-that people don't owe time or invites to even supposed family members they no longer want contact with? He said okay in our native language in a semi convinced way.

But yea-AITA for saying that ? Also relevant is I did tell him before that going forward I want family time I'm involved in to be me, him and my brother only. Hard to say how serious he realizes I am about pretty much wanting no or low contact with technical stepfamily.
