Fiance who had a nervous breakdown, DA'd himself ... but I did not give up, I hung in there and ignored the elders and everyone else. After around a year of being his emotional support, it got to be to much and the day it was over was the day he said to me "I am frightened that in 10 years you will look back on your life and regret that it was spent with me and my heart would break if that ever happened" because I realized that he was absolutely correct and it was time to move on. We are still really good friends now, but it took a long time for me to be able to date again because that who thing totally screwed with my mind.
Oh and BTW, that was caused me to seriously look at the inner working of the religion. The guy got reinstated so his family would stop shunning him, but he immediately stopped going to the hall or being a JW.
