My sister and her partner are malicious people; most of my family feels betrayed and distances themselves. I’m not going to get into a back story because me cutting ties with her is not my focus. It’s her daughters, my nieces, AITA for not wanting to know them?

I don’t like my sister we haven’t spoken in years so my thinking is why would I have to like and acknowledge  her kids. I’ve met the kids which makes it harder but, I believe relationships are not by blood but by how people treat you. I think my decision to not talk to her or her kids is best. 

If you don’t like someone why would you have to like their kids, family or not. My sister is well off not struggling. I wish them the best. I just don’t want nothing to do with them.

My family is guilting tripping me. Saying I’m messed up. My sister uses her kids to get our family to engage with her. My family feels obligation to her kids so they reach out send gifts etc. AITA?
