<human>: Can you provide a brief overview of the text?

Hey friends

to put this as short as possible: I have been with my GF for a few months now. She is recovering from anorexia and has been hospitalized in the past. She is currently still underweight and developed bulimia. She is binge eating and purging on a regular basis atm. She is in therapy.

I am more and more having trouble dealing with her ED because, despite her numerous efforts to keep it out of our relationship, it is a very far-reaching issue which affects many aspects of our relationship.

The most urgent problem:
Right now she wants to sign up at the gym where I am training. In the past, she was pretty enthusiastic about fitness and bodyshaping. She subscribed to fitness bloggers and clean-eating youtubers and whatever. However, she was doing mostly home exercises. Doing sports was never about gaining weight or muscle but more about shaping her body and having an excuse for eating. I thought of it as a rather unhealthy way of practicing fitness.

Her purging has gotten worse over the past few weeks. Right now she tells me almost daily that she had to eat and purge. I am thinking that this might not be the right time to subscribe to a gym membership.

So this is where I have no clue what I should do in this situation: I don't want her to stop doing sports since that is not a bad thing per se. But I am afraid that fitness will rather serve as kind of a "justification" for eating and that it will worsen her ED. And I am afraid that she will not raise her caloric intake to a level where she will be gaining weight, which would result in a weight loss and, despite not being anorexic any more, she is still very thin.

So redditors who might have experience in dealing with a partner who suffers from ED - what is a correct way of handling such a situation?
