"You were my best friend for years. And I miss you everyday. But if this is some attempt to incriminate me or just saying hi, then please remember what is going on with this world, and that you still know 'the truth' and what you should do to come back"
Your response was great but what if you said:
"I will come back to meeting, (preferably a Watchtower study) if you promise that while I'm there you will raise your hand and tell the audience about your experience at a recent Rap concert where you and the other JW's saw me, a former JW and suddenly had a guilty conscience and ran away. Tell them about how I called you out on it and you tried to flip the situation around and make yourself sound like a spiritually strong JW by ignoring the fact that you a JW were in a Club dancing to Rap music when you know better. Tell them how instead of explaining your own "untheocratic" actions, you had the gall to lecture me about the closeness of the end and the wickedness of this world.
Until you are willing to do that or something similar, save your preaching about world conditions and the importance of my returning to "the truth" until you actually believe it yourself and are acting in accordance to your beliefs.
(Don't be surprised if she is pretending that she wasn't at the club, you are mistaking her for someone else and are using this as an excuse to contact her.)
