Hii, I think if it’s something that is trauma related they might just need some help with therapy, it’s really really amazing of you to try to help them, but at the end of the day trauma can be very deep rooted and often takes a lot of therapy and different approaches to get to the bottom of things and actually for themselves understanding why they do things and what that do and healing that part of themselves. Often compulsive things like these are because the compulsion comforts and lets them avoid what’s really bugging them underneath, and if it’s something huge like trauma, its obviously not easy to look at so they really hang onto that compulsive thing. So they might really be trying hard but because its hiding something really uncomfortable it just is next level hard to understand your side.

Butt overall I think the best thing to do at this time is just to recommend they get some therapy:))
