<human>: This is a girl I've been dating for 10 months now. She was hospitalized for an eating disorder several years ago, but has since recovered and reached a healthy weight. 

Apparently, though, since we've been dating she's gained about ten pounds and for the last couple months is constantly talking about how she's fat and she wishes she was "small and cute." She'll look at pictures on Instagram and points out girls who have her "ideal body type." She makes these sort of comments just about every day, and it really concerns me and I don't know how to respond. She also says that her goal is to be at the minimum weight where her psychiatrist "doesn't get mad at her," because she feels like that's a "healthy compromise" where she can feel comfortable with her weight and not have it affect her self esteem. 

I've told her it makes me worried for her to be so concerned with her weight given her past struggles with an eating disorder, and I've emphasized that I don't think it's healthy to have your self esteem rely on your weight. She looks beautiful and healthy at her current weight, and if she has gained weight since we've been dating I haven't noticed it. I'm worried that having that kind of attitude could lead to her slipping straight back into her eating disorder if she experiences a period of stress or something. I also find it sort of off-putting that she's always putting herself down and making comments about her weight. When I've brought up these concerns with her she's gotten upset with me and said she feels like I'm "judging her" and that her ideal weight is where she feels comfortable or she closes up and doesn't discuss much. Is there anything else I can try to say to her? Or am I just being judgmental and irrational like she says?

Give me the gist of the text in a nutshell
<bot>: My girlfriend used to have an eating disorder. Lately she's been worried about having gained a few pounds and is constantly putting herself down about it. Is this something I should be concerned about?
