Oh boy....where to start?
If he is disfellowshipped, he may or may not want to get reinstated. That means he will have to go to meetings for months without anyone even looking at him, total ignoring. Ask him if he plans of being reinstated if he is df'ed and what it will mean.
If he is disfellowshipped and chooses NOT to get reinstated, you or your child may never ever meet his parents let alone be accepted by them, you will not be accepted by his other children nor will your child. He will lose all friends and family. Many of us on this site are victims of this family shunning. My own mother will not talk to me and has met my husband only once.
He seems older, like around 40, so why is he not willing to face up to his decisions and accept responsibility for them, why is he trying to pin it on his wife? It would scare the crap outta me to have a guy jump from such a long term relationship (16 years you say?) over to me. WOW. I applaud the other suggestion here to put some distance between you and him. Let him figure out his shit first.
Tell him you are on this site. See what he says. Tell him you don't ever want to be a JW. See what he says. Tell him you don't want him to go back to the JW's. See what he says. You will soon figure out his priorities if you ask questions like this.
You have put yourself into this tangled web of lies and deceit. It is too bad, but nothing is free and clear yet, so wait a bit until it is. Then see what happens. Go home to your parents or whereever you said you could go.
Love Jez
