Dear Sweetface,
WELCOME to the forum!!
I am so sorry about your sister!! (((HUGS))) She is angry and frusterated at your decision and your lack of loyalty to God and what she believes is God's only channel. Hang in there. We all say things when we are mad that we don't really mean. The best thing you can do is to pray that her heart open for truth, and don't give up on her. Prove her wrong, be happy, and be the same moral person you always were. JWs have been brainwashed to believe that all who leave the "truth" are miserable and are wollowing in depatchery.
My father in law, when frusterated that he couldn't keep us (his son and I ) from leaving the organization said to me " You do know that if you go down this road you will end up divorced, and _____ (our daughter) will end up with no morals.. (blah blah blah)" I just looked at him and asked what in the world would make that happen? We still love Jehovah, and are still moral people still study the Bible, and are still instilling morals in our daughter. Why would we abandon Jehovah and Jesus? He just looked at me in that silly dumb confused look! To him it didn't compute!! Jehovah=The Organization.
I hope you stick around, as many if not most of us have gone through simular experiences with our loved ones. My own brother will have NOTHING to do with me, his parents or the rest of his siblings who have all left either. He has never even given me or any of us for that matter, the opportunity to explain anything to him. He just believed all the gossip and lies and is assuming they are true. Real loving hugh? We understand your pain. Keep your chin up. You never know what may make her stop and wake up one day.
Sincerely,
Lady Liberty
