My bf and I are living in his parents home. We want to get the hell out and move to MB, SC. Any ideas?

My bf and I live with his parents and lil bro and sis. Its a hell house. We live in New York. I'm from North Carolina. We hate it here! His mother hates me! We want to move to Myrtle Beach. Compared to New York anyplace is cheaper to live but especially places in South Carolina. I've looked up apartments there with rent as low as $350 a month. I need to some feed back on a good plan to get the hell outta here! Things just get worse and worse everyday. Me and him are unbelievably happy together so the relationship is fine its just where we are that is causing the problems. He is thinking about going starting school in Sept. to be a pharmicist and I want to be a lifeguard. But we are worried about him doing that because you have to go to school for 6 years, it can be exspensive, he could be away all the time what with work AND school... Its just all so complicated and we can't get a moments peace with the 2 spoiled rotten devils... Any suggestions guys? Any at all :)?
