@SECRET_ASIAN_MAN Way back in the 1970s, a girl in our college dorm was diagnosed with anorexia, also exacerbated by a boyfriend who made her dread gaining an ounce. Her weight loss was so drastic that her parents brought her home for treatment. Back then, very little was understood about eating disorders. Hopefully you have access to much better medical and psychological resources now. Good luck.
@cassandra17lina We are TOLD the boyfriend has been trying to help her gain weight.
The real problem is he hides from us, therefore isn't communicating anything about her.
He was a professional couch surfer before they met.
