I think what upsets and annoys many people who left this organization is how insincere and
hypocritical most JWS are as well as their potent arrogance about themselves.
This so called "brother" who was wanting to dissolve your marriage to create something new
with you and himself just reeks of disingenuous personal hypocritical self concern for him and only him.
This religion as you found for yourself is pretentious and corrupt and not surprising so are the people inside of it.
The best way I found and its at times a hard thing to do, is stay clear of any JWS all together, they will only degrade you,
malign your character and show copious amounts of disrespect. Trust me I've tried and yes I was a born-in as well.
Take care.
