<human>: So when I first met my girlfriend she was at a healthy weight. However as I soon found out this wasn't always the case. Just months prior to me meeting her, she was very underweight due to anorexia; she showed me pictures and it was bad, she didn't even look like herself. As we began dating this was something she was still recovering from. She was eating, but had great difficulty doing so around other people, especially when in public. Over time she got used to eating around me, and though she still gets a little uncomfortable, she has a better time eating around others now.

The problem is as we have been dating, she has been steadily gaining weight. I initially thought that this was temporary due to her finally eating at a healthy rate and that she would see that she needed to get control of her eating habits and her weight gain would stop. This however, did not happen. I didn't want to say anything because I believed this to be a sensitive issue, and something that she needed to deal with on her own. I was also cautious about her anorexia as she was finally coming into a position where she was comfortable about how she looked and I didn't want to upset that.

Now however, to be frank, I'm losing my attraction to her. I feel bad, because the relationship has been great and I really enjoy being with her. Despite this, I don't find the weight she has put on as attractive. I recognize the shallowness of such a statement, but its how I feel, and I can't really stop it. In addition I don't like watching someone allow themselves to become unhealthy. I want to do something to help her, but I'm paralyzed. I'm terrified that she might slip back into anorexia.

I don't know what to do. How do I bring such a subject up to her? She is a really sensitive person and when she receives any kind of criticism she just folds up. How can I talk about this with her without hurting her? Should I even bring it up?
