The following advise was well received on a previous thread -
you have constitutional rights to freedom of religion, expression, belief and association,
I have advocated at various times on this site, that those wishing freedom from this or any cult should simply exercise their rights by making a written, dated, declaration of their personal religious freedom to a trusted friend or counselor/lawyer. Do this while you are still in "good standing".
It is you alone that decides what faith if any that you chose to practice and you are free to abandon any faith at any time, for any reason, without interference.
You have already ceased presenting yourself as a JW by fading from the cults meetings, commenting to espouse their propaganda and sharing in their public displays of activity - DO NOT be drawn back under the ecclesiastic authority of the congregation by allowing them to meet with you! ( the elders manual states that agreeing to meet with them affirms your acceptance of the congregations authority) DON'T DO IT!
Let them be the last to know that you have already acted in accordance with your legal rights and that any actions then taken after that fact (ie.against a non-member) will be to invite prosecution.
The link above discusses how Norman Hancock sued the Mormons for similar interference of his rights - enjoy
