Oh, there are many good responses here, but please PLEASE listen to Hortensia!!
"...but I've been around a long time and I've seen a lot of relationships. You have a responsibility to your child now. I grew up JW and it is not a good religion for children. My personal opinion is that you would be better off not getting married. You made one mistake by getting pregnant so soon, before you really knew this man. Now, don't make it worse by marrying him and his religion. ..."
The more responses I've read, the more I agree with Hortensia - Moshe, and others...
Do NOT marry this man!! Walk away - get decent child support, and then WALK AWAY.
He is ALREADY setting 'conditions' in your relationship WITHOUT getting your input - did you FREELY AGREE to the "No sex for a year" rule??? Or was pressure applied to 'assist' you in your decision...??
And that is ONLY the tip of the iceberg...
What will happen if he's NOT "reinstated" after a year?? No marriage??? NO SEX???
Some people go for YEARS - even DECADES - before the Watchtower Society's 'elders' allow them back in!!!
Do you really want your SON raised like this? With this sort of "rigid-obedience-to-rules-controlling-EVERY-aspect-of-your-life" mentality???
Let me put it another way...
The bible was basically written by Bronze-Age Middle-Eastern nomadic MALES. Would you want the likes of the Ayatollah Khomeni, the Taliban, the Al Quaida, Osama bin Laden, dictating how you are to live your life, what sort of sex you're allowed to have, what you can wear, what is deemed "modest" or "immodest", what sorts of music you can listen to, what sort of parties you're allowed to have - and how LARGE they can be, and so on????
Run now, while you still can.
If for SOME reason, you decide to STAY with this flip-flopper, MAKE SURE THAT THERE ARE NO MORE CHILDREN IN THIS RELATIONSHIP.
I was battered and bullied into the JWs by my parents, and I married a JW because that was supposedly my ONLY option.
But I knew that I'd need to move fast, some day, and I MADE SURE THAT THERE WERE NO CHILDREN. Dragging a child along in my escape would have made it a THOUSAND times more difficult.
I used birth control EVERY day of my JW life. Leaving with one child is hard; leaving with two - or more - could be disastrous.
Best of luck to you - keep your head clear and make those hard decisions that will benefit you and your child in future - not just the 'easy' route for the moment...
