(19M) (19F) My girlfriend has an eating disorder and I don’t know what to do

Me and my gf have been together for just over 2 years now and the whole time her eating disorder has been getting worse to the point of hospitalisation. The whole time we’ve been making it work and we’ve both been very patient with each other.

Recently, however, when she comes visit me at university and when we do anything together I feel that I get more agitated and bummed out when I’m around her. I think this is because she is always in a low mood/energy state because of her eating disorder, but I also counter argue in my own head that it’s just the result of me not being patient or compassionate enough to handle it. Also the fact that eating disorders often take years to beat worries me that this is going to be an issue for years to come.

I have gone over various routes and plans in my head of whether to break up or try and become someone that can handle an issue like this but I honestly have no clue on what to do. I don’t know what is best for me or for her at this point. I don’t want to spend years with a person that “drains” me when I see her but I also don’t want to give up on a person that I love so much.

I would love to hear and outside perspective on this situation and on both what type of partner I should aspire to be and also what I should look in a partner. I don’t know what a healthy relationship properly looks like as this is my first serious relationship and I’m afraid that if I break up with her that I’ll be losing something really precious over a reason that might be under my control.
