I've had my Spathiphyllum wallisii for three years now, and it's finally stopped being dramatic about humidity

I've had my Spathiphyllum wallisii for three years now, and it's finally stopped being dramatic about humidity! I moved it away from the radiator last winter and started grouping it with my other tropicals, and honestly, the shift in air moisture made all the difference. Has anyone else found that these guys are less fussy once they're not isolated? I was convinced mine was just a diva, but I think I was setting it up to fail.
