That is a tough position you are in. Personally I think termination is the wrong choice unless there is something wrong with the child that could keep it from living anyway. I don't think it to be wise or nice if you kept it from your parents just because of the JW thing. Basically if your father turns you in then he turns you in. You have been out technically for 3 years anyway and have no aspirations to return so being df'd or whatever officially wouldn't have much impact on you personally I gather. I'm not sure what it would do though to the relationship with your family if anything at all. I would hope they still would have a relationship with you but unfortunately when it comes to these situations there is so little that we can control
