Your dad is supposed to tell everything about your family to the elders. That's his duty.
If you don't go, they will be putting him in the hot seat looking for answers and he doesn't like it. People notice when you're not there-he gets the flack.
Just be patient. Are you a student? If not, do you feel that you have enough education to support yourself if you leave your parent's home? If they will help with school, you need to take advantage of it
These are tough things to think about. Especially given the fact that if you leave as an "apostate" you may be leaving your relationship with the folks behind as well.
Patience. Everything comes to he who waits.
