Hahah, I’ve killed two rufibarbas. My first one was due to a draft in the windows and the other one came with mites, and it was so bad I didn’t want to f with it. I’m on my third and it’s been a good relationship for about a year now :) they like humidity and their soil to stay very slightly damp-ish. I’ve noticed they don’t do well in an area on their own…grouping plants helps here with the humidity, and calatheas are little drama queens so if you get another one, good luck!
