Processing some stuff, and have a question.

My Mom passed back in 2021. She was Jewish, I’m Jewish. Her brother, who due to unfortunate circumstances is a catholic. I won’t get into that, but he had her cremated. Apparently it was her wish to be cremated, so I respect that. But like.. do I still bury her? Do I scatter her ashes? Because like from a Halacha perspective she shouldn’t have been cremated. I only signed off on it because that’s what she wanted, but now I’m not sure what would be best.
