My dad lost his first wife 20+ years ago. My half siblings (late 20s to early 30s) are his kids from that marriage. He met my mom three years after his first wife died and they got married and had me (17f). They were expecting my little brother when I was 2 but he was stillborn.

My half siblings never seemed that okay that dad remarried. But it wasn't so dramatic until the last couple of months. Basically it started with a confrontation about how dad better not try to bury my mom with their mom or plan for all three of them to be together and how gross that was. Then it turned into a fight over dad wanting to be buried with my mom and not theirs if he couldn't be buried with both. That continued for weeks and then they showed up to our house with some of their mom's siblings and it became this huge fight about how dad better give up his rights to the grave and never visit again and how he betrayed their mom and didn't deserve to play the grieving widow when he replaced her and even dared to have kids with his new whore.

His first wife's siblings were disgusted that he bought the grave with my half siblings mom and wanted to abandon her like he abandoned their vows when he remarried. They said he was disrespecting their sister.

It got really intense and heated and my dad was upset. He told them he didn't want to be away from either wife in death but if nobody wanted my mom with them then he couldn't abandon her either. That made it worse and they called my mom all kinds of names and said she should never have been his priority and their mom gave him four kids while mine only gave him one. That started a whole new thing off. It upset both my parents a lot.

I ended up asking my half siblings and their aunts and uncles to leave. They yelled at me for interrupting their talk with THEIR dad and I said they were bad people for treating OUR dad like that. It set them off even worse and dad made them leave himself.

They're more pissed at him now because of what I said.

AITA?
