Welcome to dating women! :D
Seriously, though, fat women go through a lot because of their size. There is so much hatred thrown their way because they are fat, and someone who is supersized even more so. When they hear the message ever since they were a kid - not talking parents, though they can help screw things up to, but their peers at and outside school, as well as in social media - that fat is bad and they are ugly because they are fat, that it is hard for that message not to become ingrained with them.
Did you get ever get the impression from her that she liked being fat and getting fatter? From what I could gather from what you said, it sounds more like she likes eating a lot and enjoyed you helping to finance that. Again, from what I am reading here - and I know that we don't see the full picture - she probably doesn't like being fat but doesn't care enough to do anything about it, but there still is an underlying desire to cave to society's pressure to lose weight. And if there is always that voice inside her head, there is nothing you can do about it, and you're going to have to deal with that as her real desire. You may luck out and she yo-yo diets her way to even bigger than she is now before she just gives up, or more likely, once she can afford it, she is going to go on semaglutide or do WLS because she feels too fat. Her doctor will frankly play a big part in this too: if she keeps getting the same message about how better she will feel and how much her health will improve if she just loses 50 lbs, then your voice will ultimately mean nothing and she'll decide to lose.
Unless she is kinda slow and eager to please/afraid to lose you so that she is more inclined to be fat and happy with you than risk your relationship on getting thinner as she thinks she wants to be, her weight loss is always going to be out there somewhere. (And by "slow", I am not talking like this moron who keeps saying we want to fatten retards; I just mean someone who doesn't think too much about the consequences about what they are doing to their bodies long-term.) She may keep it buried deep inside and not talk about it, but at some point it will bubble up to the surface and become an issue. And honestly, someone that big at some point will have to face losing weight for medical reasons, whether it be joint pain or mobility issues or diabetes or high blood pressure or whatever. Humans just aren't made to be that big long-term. (I am not one who thinks that anyone 500 lbs is going to be dead within 2-3 years, and I am one who really loves USSBBWs, but I am also realistic enough that someone who reaches 500 lbs in their 20s and then never gets smaller is not going to have a really long life.)
Now, one thing you have to weigh against this slow-burning desire to lose weight - and I am surprised nobody has raised the issue yet - is the probability of finding someone her size again. Unlike what some of the idiots here will say about how easy it is cause they could do it no problem, it is VERY difficult to find a woman who is in the 500 lb range. (Even more so at your age.) And don't expect to find a 300 lb woman who is going to be fine gaining up to that size or that this will happen "naturally". There just are not very many of them out there. And to find one with the self-confidence to not care about her size (as opposed to one, like your gf, who seems to have been beaten-down by all the negativity and bought into it) or who actually loves it/loves gaining? That is like expecting to find a unicorn. So pretty much any 500 lb woman is going to be like this woman you are dating, and it's going to be a crapshoot whether/when they will start losing. (And unlike say someone in the 300s, they really will need to do so at some point for their health/mobility.)
You really should give this more time and try to make it work, or at least see if it will. You may find she gives up on trying to lose and accepts who she is and enjoys eating, and you'll enjoy some great times together until she decides to start losing. Or you may find that not too long it becomes a deal-breaker and you can no longer stand the self-pity and drama (or possibly she is a very weak personality, since she seems to want you to help get her to lose cause she cannot do it by herself, which can be a turn-off).
I just hope we'll get to continue to hear your story and maybe at some point get a pic of you two.
