Im also going to add that, and I hate to go on a soap note here, but at times of challenges like this, the best of relationships are tested. If you can make it through then yes, they are the ones to keep around, if not, then there you go.
I will give you a personal example. My ex fiance, was all happy go lucky when I got into med school. Its was awesome, white coat ceremony and all. I got sick, so sick that I required surgery. Before my surgery, she had gone vacationing and I asked her to call me as I was down, her response "No I cant call you, not even for 5 min, you have too many issues, first medical school and now health issues". She told me this when I had to take a medical leave, and needed surgery about 3 weeks prior to. My point is, when you go through life changing things such as medical school, whoever sticks by you is worth to keep around. In return you have to promise her youll be there for her as well.
But for most medical students, its us who will need the sacrificing first. Just my 2 cents.
I get it you obviously love her, and want to be with her. Its not fair to her she has to move everything for you, and its not fair to you, you have to switch schools. This is where the "testing" part is and will likely define your relationship.
