Sorry that things are as they are for you right now.....
You are caught between a rock and a hardplace right now with no real easy answers; you have competing affections and love for your parents as well as your boyfriend and that is perfectly natural given your situation.
You have to consider what is right for you and your own...your dad will still have your mum regardless of this situation and you will have nobody or the prospects of reconcilliation with an abusive husband if you go along with their wishes. Perhaps things will work out with your boyfriend...perhaps they wont...nobody can tell but either way you deserve to have the freedom to live your life the way you want to...and to make decisions for yourself...to learn by your own mistakes (or someone elses if you are clever about it).
This is classic emotional blackmail and perhaps in your Dads defense he doesnt actually realise it but it is and you cannot allow yourself to be swayed by it...if you do you will resent your parents for a long time afterwards and surely they dont want that. You have made your decision and now the decision is with your Dad as to whether he accepts it, if he or you suffer as a result of his decision then that is not your fault...its his!
In my view your boyfriend is a side issue and one your Dad is playing on because of the rumours flying round but the real issue is...you dont wish to be a Jehovahs Witness anymore and you and your parents must find some way in which to deal with this fact and accept each other for your choices.
I do hope it goes well and that your parents listen to their paternal/maternal instincts as opposed to their indoctrinated ones.
Be strong...
