I will keep affirming that this person can at some point come to grips with the reality that they have developed a particularly complex and rare disorder and it has affected their entire lives. I am trying to explain face on so maybe they will get it someday.
I do care very much about them. But this denial thing is extremely self and OTHER-destructive of theirs. I could have ended up a victim in a dangerous way if I didn't keep working on distancing myself from them frequently.
