@Steph it is likely the recent district convention has caused this change in attitude.
Don't remember why you were DF'd but you can petition her emotional side. If you are not practicing what she considers sin ask why she would abandon you. Use the word abandon. Ask her to explain how 1 Corinthians 5 applies to those who are no longer practicing sin?
Ask her if she considers you the AntiChrist. 2 John 10 when it speaks of not greeting a person it is speaking of the AntiChrist. in other words a person who doesn't believe Jesus came in the flesh.
Tell her you want to assure her you would never forsake the sacrifice of Jesus.
These are perplexing things for JW's because if you read the scriptures carefully there honestly isn't a basis for shunning you to a degree WORSE than a tax collector.
