Belated welcome and thanks for sharing your story. You were treated very horribly by those elders, they were totally in the wrong. What is incredible is that had you been an elder and it was found out by the elder body that you had done something similar, you would have been allowed to continue as an elder with no one in the congregation the wiser. They reason that the fact an elder wasn't found out for a number of years and he continued his elder duties was proof God had forgiven him and he was repentant. Total double standard. By all biblical rules you showed repentance by changing your conduct.
But no matter, their harsh, unloving and unchristian attitude woke you up, so it was all for the best. The Watchtower is its own worst enemy, they are diving people away and hooray for that.
