Hi TW, your english is great, no problems understanding you at all, and like everyone said.... take.... your.... time...
It is quite difficult at first, a flood of emotions go through you, you don't want to 'be the bad guy' and call anyone mean, call anyone a liar, or "assume" anything....
Just let yourself do research (this is a great place because EVERYONE on this site has done the same as you.... wondered, searched, been confused, been mad, been hurt) and DON'T TELL EVERYONE what you have done.
Give yourseslf time... If you want to help your family out... be very careful..... go slow.... it is difficult.
Ever wonder why they same the same things every meeting? Every week? Propaganda... they know they have to repeat, repeat.... So, why not create a circumstance where your family is NOT at every meeting?
Join a class? a club? take trips? Move? Start getting "Worldly friends" so that when you DO decide to leave.... if you do, you will have friends...
Good "luck" ....& hugs cha ching
