My girlfriends parents can't afford her anymore so now I'm the one paying for her expenses

I'm 24 and my girlfriend is 21. She's never had any real job and her parents have provided her everything but now they told her they can't afford her anymore, and that it's time for her to take responsibility for herself. Now I don't know what to say. I love her to death, and I want to do everything for her. I pay for her, I buy her new clothes, I took her to Europe last year and I took her out to good restaurants. I wanna give her the world but I don't know what to say to her parents. They keep texted me everyday that their daughter is now my responsibility to provide for her. <br><br>I feel like I'm now her provider and her parents wants me to provide for her because she's of marrying age for them. She told me if I really love her I'll provide for her and buy her everything she needs. I'm starting to feel like I'm being used for money and I don't know what to do anymore.
