That's horrible, what your parents are doing. No one should have to choose between love and an education. Unfortunately, there doesn't seem to be an easy way out of this. Perhaps you could "break-up" and carry on with your relationship discreetly? If push comes to shove, though, you do what your heart tells you. No one can tell you what to do or how to feel. Your love together is just as valid as the love between a guy and a girl, and if you two make each other better people, then I see no reason to actually comply with your parents. Lots of hugs, and
PM if you need to talk.
