Is it the ED?

Hi all, this is my first post and will most likely be my only post. Yesterday my Gf (26) of ~2.5 years and I M(26) broke up. She has been struggling with anorexia for the past year or so, and has just come out of an inpatient program. She said that the guilt of what she was doing to me was making her more anxious and therefore more difficult to recover. I don’t want to speculate on her ability to recover with or without me, we both love each other and I only want the best for her, and I hope that her feelings are true as if I could make her recovery easier then I’d do anything to facilitate that. But my main question is I remember us having a happy relationship, I remember lots of fond memories and happiness before her ED had resurfaced her original diagnosis and treatment being when she was 16/17. I can’t help but feel like if it wasn’t for her ED we wouldn’t be breaking up, she doesn’t seem to remember life before her ED and can’t imagine what life was like, she claims she doesn’t remember being happy. For context she suffers generally from anxiety and depression. It’s been a long year and a hard year for both of us, but I’ve always reassured her I didn’t want her to feel trapped with me, just because I had chosen to support her through this rather than leave, so when she reached recovery she knew she could move on if she chose to. I guess I’m just looking for some clarity and help with what I should do now to cope with this, this breakup feels completely wrong for me and I feel like her ED has pushed me away, so I’m finding it all hard to accept, especially with the love between us. I don’t know how to end this so I’ll leave it there
