Hi Sanchy,
I can feel very much for you as I was in a similar situation. I was also about your age when I resigned as elder.
The advice Tim Drake and freddo gave is really good.
In my situation it ended sadly in divorce and me df'd for apostasy (a long and painful journey). I must say though my ex wife is and was a hardcore JW. I am happy though to be able to live according to my conscience and to give all my love to my little son without faking a jw life.
My advice is to give all your love to your children and wife but to be authentic and act according to your conscience but always respectful.
You did already a huge step. To resign.
If you need to talk you can also pm me.
