Only thing you can do is be there for her, she has to make her own decisions. Running back to the JW's won't solve anything, it will only confuse things further. If you are a JW.. you are no longer a safe harbor, you are a "brother" It puts you into an entirely different catagory.
Be her friend and a shoulder to cry on.. nothing more. I married the shoulder that carried me out of my abusive relationship, so I should know.
You made positive changes in your life, you can maintain them.. you don't need a committee of elders to keep you in line.
