Hi Danni,
Welcome back! Just don't be harsh on yourself. Your children have a great parent, smart and caring. Mistakes, especially those made when we are most vulnerable, are forgivable. You joined the JW's because you thought they were a good place for you children. You acted out of love and concern for them.
My wife also married a non-believer and was marked for it. Before the wedding she got a talk especially intended for her; I know it because I was there. She was called a STAIN. Nice! I was the one who stained her. But stupid me, I failed to see the obvious until I joined this forum five years ago (18 years after our wedding). I was blinded by the love bombing, well behaving, well intended rank and file, but remained ignorant of the leadership, thinking that the humble brothers and sisters were a mirror image of it.
Even though I have been an atheist my whole adult life, I was nonetheless fooled by the neat veil of the JW's. So much that I bought into their BS and accepted the possibility, even with pride, that my two children would become two shining Bethelites.
The benefit from joining this forum is that I saw through the Watchtower BS and was able to rescue my youngest. I don't lose hope that one day my wife and daughter will give the finger to the Watchtower. If it ever happens, the process will be painful; all their friends and family are in. But knowing what I know from people like you, I will make my best effort to fill with love the void left by a deceiving cult.
