You don't have to be a doctor to recognize the basic visible symptoms of a mental disorder. Her lower jaw and cheeks are still a bit pudgy while her body is very thin, this could very well be bulimia.
Even if it was just anorexia she's still unhealthy and needs to quit.

If you want her to get worse in the future by all means be my guest, some people just don't like seeing others suffer. She may think she isn't suffering now, but she is mentally ill. His shit can spiral fast without you realizing this, anon. She's young so she can recover easily without worrying about damage.
