Conan you were so courageous!! I hope you are OK too. It must have hurt a little to bring these truths to your friends and have this confrontation with them. It sounds like it ended much better than it could have, with you offering support to them if they need it and hugs all around. I am very glad your mother went with you, and it would have gotten much uglier. Witnesses are very reticent for outsiders to see any of the ugliness, so she was a very good protection.
In your religious search be very careful to avoid high control groups, this has been a good education for you.
