You need to understand that it sucks. Parents interfering is ridiculous. But that sort of thing always happens. But you also need to see, that you're still young. You may suspect she's the one now, but you still have so much time to go out and meet people. To grow as a person. Everyone changes. You'll change, take on different life paths. Things will fall into place.
Everything happens for a reason. Good things fall apart for one reason or another, so that perhaps something better can come along. Good luck.
