Hi I'm sorry about your situation.
Here is what I would do. Talk calmly to your family and see why they are against the relationship. Consider their thoughts and feelings. If they are being unrealistic and controlling, then I would make plans to move out. You could would work multiple jobs. This would allow you to be away from home more often and away from their controlling tendencies. Save, Save, Save money until you can afford to find a place (room or apt) to live on your own. Maybe you have to move away from your family to avoid the higher cost of living. Once you have living arrangement, you will be totally free from your family's controlling ways. Keep working hard until you have your basic necessities met. Then, you can save for some form of transportation (car/motorcycle/bike).
I agree with @Daphne .comments. I would think of this as adventure with a great reward at the end. You get to be with your fiance/wife and you'll be so busy working, you won't notice the long wait.
A lot of information is left out in your post. How old are you? What country you're from? Do you have public transportation? Feel free to share if you feel comfortable.
