Hey stuck...
Not sure of your exact situation but my opinion is to make a clean break. Just DA and get out of dodge. No relationship is worth losing your personal freedom over. When I woke up I told my mother I would stay in for her sake but I was not going to hide anything. That lasted for about 6 months until I got a knock on the door from two caring elders. I had it out w/ them and formally notified them of my intention to leave.
If you formally leave you dont have to hide your personal beliefs and you dont have to play any fucked up games w/ people who will ditch you in a moments notice. Personal freedom over ALL else.
good luck
