PLZ HELP WITH THIS FRIEND PROBLEM AND IDK WHAT TO DO!?

You should get a new friend. Yor friend is ungrateful and if she doesnt know how to treat you you sholdnt takeher. You paying for her is a privelege not a right so she either learn how to treat you or stays home. You get back what you put out and if she puts no effort into being a good friend to you , you shouldnt waste your time doing it for her.
