If this is unacceptable, why should we be girlfriends? Friends just want you to get better, not hold you back. She likes eating and being fat, and no one will hold you back. This is not a friend's performance. If you want to make progress, you can enter a higher circle and see a better world. If she doesn't want to, I don't think there is anything wrong with staying away. Some people are destined to be passers-by. Of course, as a friend, you can also try to help her. Ingratitude is her business.
