Stand your ground and tell her that you will not finance an immoral lifestyle. If she wants the tuition money it's simple, she needs to send her boyfriend packing. Stress to her that he is using her and she should look for a man who would cherish her enough to propose marriage.
Make sure she knows it's not about the money, it's about her future and her soul, that you're standing up for principles out of your love for her.

Thank you for your kind words and understanding. I feel kind of sappy saying it, but I guess it's what I wanted to hear.
