My peace lily has been riding the line between barely alive and thriving for two years now

My peace lily has been riding the line between barely alive and thriving for two years now. Finally figured out it hates my hard water—switched to letting tap water sit overnight and the leaf browning basically stopped. It's still not flowering, which I read means it wants more humidity, but honestly I'm just happy it stopped looking angry at me. Anyone else have one that's stubborn about blooming in a dry climate?
