How to nicely tell my brother I don't want to talk about him molesting me anymore

I was molested by my brother when he was 10 and I was 5. It's an extremely complicated situation that I already forgave him for. Our old priest and his wife fostered us. My brother was an altar boy for this priest and sadly became another priest altar boy statistic. That priest was disgusting and my brother mainly touched me. He was raped by priest several times and caught STDs before he was even 11. We worked through this in therapy. I forgave him. He will randomly apologize for it again every few months and call me tears to apologize and I honestly don't like being reminded of it. I know he holds a lot of guilt but I really just want him to stop bringing it up. I don't want anymore apologies. How do I tell him that?
