Don't know what to do and I don't want to lose him

Soooo my parent want to move, I really really do not want to move away but I don't know how to tell them. I am willing to stay with my grandma and to look after her until I can stand on my own feet because I am done with school... My parents are very strict and I am afraid they will make me move with them but I really don't want to yes I am 18 but yes I will provide for myself and get a job and everything... My bf and I both don't believe in long distance and I also don't want to lose him because of my parents making me move... I actually though of getting him a job where we move, if we move... But then he will have to stay with us for a while and again I don't know if my parents will allow that ... I really don't want to go... Any ideas from you guys that can help me ? Please
