I was born and raised a jw...until I was 18. I left when I turned 18, for many reasons but especially because my parents drilled it into my head that everything I did as a child would reflect back onto them in Jehovah's eyes.
They would sit with us (my two sisters and me) and have these "family meetings" and tell us how they were scared sometimes because of some of the things we did (stupid things like accidentially swear or say something mean or rude to someone...little things...) and they would tell us, If armageddon came tomorrow they didn't know if they would get to live in the "new system" based upon the things WE had done. Since we were little kids everything that we did NOW would effect THEM in the END. Now, that is a terrible, awful way to grow up!
My point is this...BE CAREFUL! Witnesses are VERY tricky. I would hate for you to get "sucked" in and then have to raise your children the JW way. I think you already can sense that they have their "ways" to get someone involved. I think it's wonderful that you are putting your children first in your life...Don't compromise them, stay strong.
TRUST ME when I say...It's a horrible way to be raised.
